Java Example Boot

# Creating a Standalone Java Boot Application (Without JAR)

Here's how to create a Java Swing application that simulates a boot process and can be run directly without needing a JAR file:

## Complete Implementation

```java
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class VirtualBoot {
    public static void main(String[] args) {
        // Create and show the boot screen
        SwingUtilities.invokeLater(() -> {
            BootScreen bootScreen = new BootScreen();
            bootScreen.setVisible(true);
            bootScreen.startBooting();
        });
    }
}

class BootScreen extends JFrame {
    private JLabel bootLabel;
    private JProgressBar progressBar;
    private Timer timer;
    private int progressValue = 0;
    private String[] bootMessages = {
        "Initializing virtual hardware...",
        "Loading virtual BIOS...",
        "Checking virtual memory...",
        "Detecting virtual storage...",
        "Loading virtual OS kernel...",
        "Starting virtual services...",
        "Preparing virtual environment...",
        "Virtual boot complete!"
    };
    private int currentMessageIndex = 0;

    public BootScreen() {
        // Configure the window
        setTitle("Virtual Machine Boot");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setUndecorated(true); // Remove window decorations
        setExtendedState(JFrame.MAXIMIZED_BOTH); // Full screen
        
        // Set black background
        getContentPane().setBackground(Color.BLACK);
        setLayout(new BorderLayout());
        
        // Boot label with green text (classic terminal style)
        bootLabel = new JLabel("", SwingConstants.CENTER);
        bootLabel.setForeground(new Color(0, 255, 0)); // Green text
        bootLabel.setFont(new Font("Courier New", Font.BOLD, 20));
        add(bootLabel, BorderLayout.CENTER);
        
        // Progress bar at bottom
        progressBar = new JProgressBar(0, 100);
        progressBar.setStringPainted(true);
        progressBar.setForeground(new Color(0, 255, 0)); // Green
        progressBar.setBackground(Color.BLACK);
        progressBar.setFont(new Font("Courier New", Font.PLAIN, 12));
        add(progressBar, BorderLayout.SOUTH);
        
        // Create timer for boot animation (1.5 second intervals)
        timer = new Timer(1500, e -> updateBootProgress());
    }
    
    private void updateBootProgress() {
        // Update boot message
        if (currentMessageIndex < bootMessages.length) {
            bootLabel.setText(bootMessages[currentMessageIndex]);
            currentMessageIndex++;
            
            // Play beep sound for certain steps
            if (currentMessageIndex == 1 || currentMessageIndex == 4) {
                Toolkit.getDefaultToolkit().beep();
            }
        }
        
        // Update progress (with some randomness)
        progressValue += 8 + (int)(Math.random() * 8);
        if (progressValue > 100) progressValue = 100;
        progressBar.setValue(progressValue);
        progressBar.setString("BOOT PROGRESS: " + progressValue + "%");
        
        // When boot completes
        if (progressValue >= 100) {
            timer.stop();
            
            // Show completion for 2 seconds then launch virtual desktop
            new Timer(2000, e -> {
                dispose();
                launchVirtualDesktop();
            }).start();
        }
    }
    
    private void launchVirtualDesktop() {
        VirtualDesktop desktop = new VirtualDesktop();
        desktop.setVisible(true);
    }
    
    public void startBooting() {
        timer.start();
    }
}

class VirtualDesktop extends JFrame {
    public VirtualDesktop() {
        setTitle("Virtual Desktop Environment");
        setSize(800, 600);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        // Create a simple desktop UI
        JPanel desktop = new JPanel(new BorderLayout());
        desktop.setBackground(new Color(0, 128, 128)); // Teal background
        
        // Menu bar
        JMenuBar menuBar = new JMenuBar();
        JMenu systemMenu = new JMenu("System");
        JMenuItem exitItem = new JMenuItem("Exit");
        exitItem.addActionListener(e -> System.exit(0));
        systemMenu.add(exitItem);
        menuBar.add(systemMenu);
        setJMenuBar(menuBar);
        
        // Desktop content
        JLabel welcomeLabel = new JLabel("Virtual Machine Ready", SwingConstants.CENTER);
        welcomeLabel.setFont(new Font("Arial", Font.BOLD, 24));
        welcomeLabel.setForeground(Color.WHITE);
        desktop.add(welcomeLabel, BorderLayout.CENTER);
        
        // Status bar
        JPanel statusBar = new JPanel(new FlowLayout(FlowLayout.RIGHT));
        statusBar.add(new JLabel("Virtual CPU: 2 cores | Memory: 4GB | Disk: 50GB"));
        desktop.add(statusBar, BorderLayout.SOUTH);
        
        add(desktop);
    }
}
```

## How to Run Without JAR

1. **Save the code** as `VirtualBoot.java`
2. **Compile** with:
   ```
   javac VirtualBoot.java
   ```
3. **Run** with:
   ```
   java VirtualBoot
   ```

## Key Features

1. **Realistic Boot Sequence**:
   - Simulated hardware initialization
   - Progress percentage with random increments
   - Classic terminal-style green text on black background

2. **Full Boot Process**:
   - BIOS-like startup screen
   - Progress bar showing boot status
   - Automatic transition to virtual desktop

3. **Virtual Desktop**:
   - Simple menu system
   - System information display
   - Clean teal-colored interface

4. **No JAR Required**:
   - Runs directly from compiled class files
   - No need for packaging or special execution

## Customization Options

1. **Change Boot Messages**:
   ```java
   private String[] bootMessages = {
       "Your custom message 1",
       "Your custom message 2",
       // etc...
   };
   ```

2. **Add BIOS Logo**:
   ```java
   // Add to BootScreen constructor
   JLabel logoLabel = new JLabel("VIRTUAL BIOS v1.0", SwingConstants.CENTER);
   logoLabel.setForeground(Color.CYAN);
   logoLabel.setFont(new Font("Courier New", Font.BOLD, 28));
   add(logoLabel, BorderLayout.NORTH);
   ```

3. **Add Sound Effects**:
   ```java
   // Play beep at specific points in updateBootProgress()
   if (currentMessageIndex == 2) {
       Toolkit.getDefaultToolkit().beep();
   }
   ```

4. **Make Boot Faster/Slower**:
   ```java
   // Change the timer interval (milliseconds)
   timer = new Timer(1000, e -> updateBootProgress()); // 1 second intervals
   ```

This implementation provides a complete virtual boot experience that runs as a standard Java application without requiring JAR packaging.

Java example animation Boot


# Java Swing Boot Animation Simulation

Here's a Java Swing application that simulates a computer booting process with a graphical boot screen:

```java
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class BootAnimation extends JFrame {
    private JLabel bootLabel;
    private JProgressBar progressBar;
    private Timer timer;
    private int progressValue = 0;
    private String[] bootMessages = {
        "Initializing hardware...",
        "Loading BIOS...",
        "Checking memory...",
        "Detecting storage devices...",
        "Loading operating system...",
        "Starting services...",
        "Preparing desktop environment...",
        "Boot complete!"
    };
    private int currentMessageIndex = 0;

    public BootAnimation() {
        setTitle("System Boot Simulation");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setUndecorated(true); // Remove window decorations for full-screen effect
        setExtendedState(JFrame.MAXIMIZED_BOTH); // Start maximized
        
        // Set black background
        getContentPane().setBackground(Color.BLACK);
        setLayout(new BorderLayout());
        
        // Boot label with white text
        bootLabel = new JLabel("", SwingConstants.CENTER);
        bootLabel.setForeground(Color.WHITE);
        bootLabel.setFont(new Font("Monospaced", Font.PLAIN, 24));
        add(bootLabel, BorderLayout.CENTER);
        
        // Progress bar at bottom
        progressBar = new JProgressBar(0, 100);
        progressBar.setStringPainted(true);
        progressBar.setForeground(Color.GREEN);
        progressBar.setBackground(Color.BLACK);
        progressBar.setFont(new Font("Monospaced", Font.PLAIN, 14));
        add(progressBar, BorderLayout.SOUTH);
        
        // Create timer for boot animation
        timer = new Timer(1000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                updateBootProgress();
            }
        });
    }
    
    private void updateBootProgress() {
        if (currentMessageIndex < bootMessages.length) {
            bootLabel.setText(bootMessages[currentMessageIndex]);
            currentMessageIndex++;
        }
        
        progressValue += 10 + (int)(Math.random() * 5); // Random increment
        if (progressValue > 100) progressValue = 100;
        progressBar.setValue(progressValue);
        progressBar.setString(progressValue + "%");
        
        if (progressValue >= 100) {
            timer.stop();
            // After boot completes, show desktop or close after delay
            Timer closeTimer = new Timer(2000, new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    dispose();
                    // Here you would launch your main application
                    new DesktopEnvironment().setVisible(true);
                }
            });
            closeTimer.setRepeats(false);
            closeTimer.start();
        }
    }
    
    public void startBooting() {
        timer.start();
        setVisible(true);
    }
    
    // Simple desktop environment that would show after boot
    static class DesktopEnvironment extends JFrame {
        public DesktopEnvironment() {
            setTitle("Desktop Environment");
            setSize(800, 600);
            setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            
            JLabel desktopLabel = new JLabel("Desktop Environment Loaded", SwingConstants.CENTER);
            desktopLabel.setFont(new Font("Arial", Font.BOLD, 24));
            add(desktopLabel);
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new BootAnimation().startBooting();
            }
        });
    }
}
```

## Features of this Boot Animation:

1. **Full-screen boot screen** with black background (like real BIOS screens)
2. **Progressively displayed boot messages** that simulate different boot stages
3. **Animated progress bar** that shows boot completion percentage
4. **Automatic transition** to a "desktop environment" after boot completes
5. **Monospaced font** for authentic computer terminal look

## How to Enhance This Further:

1. **Add BIOS logo** at the beginning:
```java
// Add this to the constructor
JLabel logoLabel = new JLabel(new ImageIcon("bios_logo.png"));
add(logoLabel, BorderLayout.NORTH);
```

2. **Add POST beep sound**:
```java
Toolkit.getDefaultToolkit().beep(); // Add this at appropriate places
```

3. **More realistic timing** with varying delays between steps:
```java
// Replace the timer with variable delays
Timer messageTimer = new Timer(0, new ActionListener() {
    private int[] delays = {1500, 1200, 800, 2000, 2500, 1800, 1200, 1000};
    // ...
});
```

4. **Add hardware detection details**:
```java
String[][] detailedMessages = {
    {"CPU: Intel Core i7-9700K @ 3.60GHz", "Memory: 32768MB OK"},
    // ... more hardware info
};
```

5. **Make it interactive** (press ESC to enter BIOS setup):
```java
getRootPane().getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW).put(
    KeyStroke.getKeyStroke(KeyEvent.VK_ESCAPE, 0), "enterBIOS");
getRootPane().getActionMap().put("enterBIOS", new AbstractAction() {
    public void actionPerformed(ActionEvent e) {
        showBiosSetup();
    }
});
```

Would you like me to explain any part in more detail or add any specific features to this boot animation?

Java Camera

        public void stopRecording() {

                if (dos != null) {

                    dos.close();
                }
                if (fos != null) {
                    fos.close();
                }
            } catch (IOException e) {
                JOptionPane.showMessageDialog(CameraCaptureApp.this, 
                    "Error stopping recording: " + e.getMessage());
            } finally {
                dos = null;
                fos = null;
            }
        }
    }
}
```

## Key Features:

1. **Image Loading**: Load images from file system (can be extended for camera/Android)
2. **Image Capture**: Simulates camera capture (replace with real camera API)
3. **Video Recording**:
   - Start/Stop recording
   - Pause/Resume functionality
   - Save to user-specified location
4. **Image Saving**: Save captured images to file

## For Real Camera/Android Integration:

To make this work with actual cameras or Android devices, you would need:

1. **For Webcam/Monitor Capture**:
```java
// Using JavaCV (OpenCV wrapper)
OpenCVFrameGrabber grabber = new OpenCVFrameGrabber(0); // 0 for default camera
grabber.start();
Frame frame = grabber.grab();
// Convert Frame to BufferedImage
```

2. **For Android Device Camera**:
   - Set up an Android app that streams camera to a server
   - Connect your Java Swing app to that server
   - Or use Android Debug Bridge (ADB) to capture screens

3. **Proper Video Encoding**:
```java
// Using JavaCV
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("output.mp4", width, height);
recorder.setFormat("mp4");
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
recorder.start();

Java Screen Recorder

# Java Swing Desktop Screen Recorder with Network Streaming

I'll help you create a Java Swing application that can:
1. Display the desktop screen in real-time
2. Record the desktop screen with pause/resume functionality
3. Save the recording to a file
4. Stream the video over a network

```

## Important Notes About This Implementation:

1. **Video Encoding**: This example doesn't include proper video encoding. In a real application, you would use a library like:
   - Xuggler
   - JavaCV (OpenCV wrapper)
   - JCodec

2. **Performance**: Screen recording is resource-intensive. The current implementation captures at ~30 FPS but may need optimization for different systems.

3. **Network Streaming**: The streaming implementation is basic. For a production app, consider:
   - Using proper video compression
   - Implementing a protocol like RTMP
   - Adding authentication

4. **Pause Functionality**: The pause button stops frames from being saved/streamed but continues screen capture.

## To Improve This Application:

1. Add proper video encoding using a library like JavaCV:
```java
// Example with JavaCV
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("output.mp4", screenWidth, screenHeight);
recorder.setFormat("mp4");
recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
recorder.start();
```

2. Add file chooser dialog to select output location:
```java
JFileChooser fileChooser = new JFileChooser();
if (fileChooser.showSaveDialog(this) == JFileChooser.APPROVE_OPTION) {
    outputFile = fileChooser.getSelectedFile();
}
```

3. Add quality settings (resolution, FPS, compression)

Java Splash Flash Screen Loading Load

# Java Swing Splash Screen with Progress Bar and Time Limit

Here's a complete implementation of a splash screen with a progress bar that loads within a specified time limit:

```java
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class TimedSplashScreen extends JWindow {
    private JProgressBar progressBar;
    private Timer progressTimer;
    private Timer countdownTimer;
    private int timeLimitSeconds = 5; // 5 seconds time limit
    private int progress = 0;
    private JLabel timeLabel;

    public TimedSplashScreen(int displayTimeSeconds) {
        this.timeLimitSeconds = displayTimeSeconds;
        
        // Set up splash screen
        setSize(400, 300);
        setLocationRelativeTo(null); // Center on screen
        
        // Create content panel with gradient background
        JPanel content = new JPanel(new BorderLayout()) {
            @Override
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);
                Graphics2D g2d = (Graphics2D) g;
                GradientPaint gradient = new GradientPaint(
                    0, 0, new Color(70, 130, 180), 
                    getWidth(), getHeight(), new Color(135, 206, 250));
                g2d.setPaint(gradient);
                g2d.fillRect(0, 0, getWidth(), getHeight());
            }
        };
        content.setBorder(BorderFactory.createLineBorder(Color.DARK_GRAY, 2));
        
        // Add application logo/text
        JLabel logo = new JLabel("My Application", JLabel.CENTER);
        logo.setFont(new Font("SansSerif", Font.BOLD, 24));
        logo.setForeground(Color.WHITE);
        content.add(logo, BorderLayout.CENTER);
        
        // Create progress bar
        progressBar = new JProgressBar(0, 100);
        progressBar.setStringPainted(true);
        progressBar.setForeground(new Color(34, 139, 34));
        progressBar.setBorder(BorderFactory.createEmptyBorder(5, 10, 5, 10));
        
        // Create time remaining label
        timeLabel = new JLabel("Loading...", JLabel.CENTER);
        timeLabel.setForeground(Color.WHITE);
        timeLabel.setFont(new Font("SansSerif", Font.PLAIN, 12));
        
        // Add components to panel
        JPanel bottomPanel = new JPanel(new BorderLayout());
        bottomPanel.setOpaque(false);
        bottomPanel.add(progressBar, BorderLayout.CENTER);
        bottomPanel.add(timeLabel, BorderLayout.SOUTH);
        content.add(bottomPanel, BorderLayout.SOUTH);
        
        setContentPane(content);
        
        // Set up progress timer
        progressTimer = new Timer(50, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                progress++;
                progressBar.setValue(progress);
                progressBar.setString("Loading " + progress + "%");
                
                if (progress >= 100) {
                    progressTimer.stop();
                    dispose();
                    showMainApplication();
                }
            }
        });
        
        // Set up countdown timer
        countdownTimer = new Timer(1000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                timeLimitSeconds--;
                timeLabel.setText("Time remaining: " + timeLimitSeconds + " seconds");
                
                if (timeLimitSeconds <= 0) {
                    countdownTimer.stop();
                    progressTimer.stop();
                    dispose();
                    showMainApplication();
                }
            }
        });
    }
    
    public void showSplash() {
        setVisible(true);
        progressTimer.start();
        countdownTimer.start();
    }
    
    private void showMainApplication() {
        // Create and show your main application window here
        JFrame mainFrame = new JFrame("Main Application");
        mainFrame.setSize(800, 600);
        mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        mainFrame.setLocationRelativeTo(null);
        
        // Add your actual application content here
        JLabel welcomeLabel = new JLabel("Welcome to the Application!", JLabel.CENTER);
        welcomeLabel.setFont(new Font("SansSerif", Font.PLAIN, 24));
        mainFrame.add(welcomeLabel);
        
        mainFrame.setVisible(true);
    }
    
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                // Show splash screen for 5 seconds
                TimedSplashScreen splash = new TimedSplashScreen(5);
                splash.showSplash();
            }
        });
    }
}
```

## Key Features:

1. **Time-Limited Display**:
   - The splash screen automatically closes after the specified time (5 seconds by default)
   - Countdown timer shows remaining time

2. **Animated Progress Bar**:
   - Smooth progress animation from 0% to 100%
   - Percentage display on the progress bar
   - Custom color scheme

3. **Visual Design**:
   - Gradient background
   - Centered application title/logo
   - Clean border around the splash screen

4. **Automatic Transition**:
   - When time expires or progress completes, the main application launches
   - Proper disposal of splash screen resources

## Customization Options:

1. **Change Display Time**:
   ```java
   // In main method:
   TimedSplashScreen splash = new TimedSplashScreen(10); // 10 seconds
   ```

2. **Add Your Logo**:
   ```java
   // Replace the JLabel with an ImageIcon:
   ImageIcon logoIcon = new ImageIcon("path/to/logo.png");
   JLabel logo = new JLabel(logoIcon, JLabel.CENTER);
   ```

3. **Change Colors**:
   ```java
   // Modify the GradientPaint colors:
   new GradientPaint(0, 0, new Color(31, 58, 147), 
                    getWidth(), getHeight(), new Color(69, 162, 152));
   ```

4. **Add Loading Messages**:
   ```java
   // Add to progress timer action listener:
   String[] messages = {"Loading modules...", "Initializing data...", "Almost done..."};
   if (progress % 25 == 0) {
       timeLabel.setText(messages[progress/25]);
   }
   ```

5. **Make Progress Match Actual Loading**:
   Replace the simulated progress with actual loading tasks:
   ```java
   // Instead of the timer, update progress during actual loading:
   public void updateProgress(int value) {
       progressBar.setValue(value);
       progressBar.setString("Loading " + value + "%");
   }
   ```

This implementation provides a professional-looking splash screen that can be easily customized to match your application's branding while enforcing a time limit for the display.

   // Add to download loop
   long speed = (downloadedBytes.get() * 1000) / (elapsedTime + 1); // bytes/sec
   statusLabel.setText(String.format("%.1f KB/s", speed/1024.0));
   ```

3. **Add File Save Dialog**:
   ```java
   JFileChooser fileChooser = new JFileChooser();
   if (fileChooser.showSaveDialog(this) == JFileChooser.APPROVE_OPTION) {
       File outputFile = fileChooser.getSelectedFile();
       // Use this file in your FileOutputStream
   }
   ```

4. **Add Multiple Downloads**:
   You could extend this to handle a download queue with multiple files

Would you like me to explain any specific part in more detail or add additional features to this implementation?

Java Video Player

# Java Swing Video Player with File and Network Support

I'll create a comprehensive video player application using Java Swing that can play videos from both local files and network streams. The player will include play/pause/stop controls, a seek bar (JSlider), time display, and a JTable to select videos.

```

## Features Implemented

1. **Video Playback**:
   - Play, pause, stop functionality
   - Support for both local files and network streams
   - Uses VLCJ library for robust media playback

2. **Progress Tracking**:
   - JSlider for seeking through video
   - Time labels showing current time and total duration
   - Automatic progress updates

3. **Video Selection**:
   - JTable listing available videos
   - Differentiates between local and network videos
   - Click to play selected video

4. **Network Support**:
   - Can play HTTP, RTSP, and other network streams
   - Handles both progressive download and streaming protocols

## Requirements

1. **VLC Media Player** must be installed on the system
2. **VLCJ** library (add to your project):
   ```xml
   <dependency>
       <groupId>uk.co.caprica</groupId>
       <artifactId>vlcj</artifactId>
       <version>4.7.3</version>
   </dependency>
   ```

## How to Use

1. Add the VLCJ dependency to your project
2. Install VLC Media Player on your system
3. Update the sample video paths in `loadSampleVideos()` to point to your actual video files or streams
4. Run the application

## Key Components Explained

1. **EmbeddedMediaPlayerComponent**: The core VLCJ component that handles video playback
2. **MediaPlayer Controls**: Provides play, pause, stop functionality
3. **Progress Timer**: Updates the slider and time labels periodically
4. **VideoTableModel**: Custom table model to display video information
5. **Network Support**: The player automatically handles network streams via standard URLs

## Possible Enhancements

1. Add volume control
2. Implement playlist functionality
3. Add fullscreen mode
4. Support for subtitles
5. Video quality selection for network streams
6. Buffering indicators for network playback
