Java对象文件sleep线程动态演示

如果您想动态演示Java对象文件加密过程，可以使用Java Swing提供的GUI组件。以下是一个简单的例子：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.io.*;
import java.util.ArrayList;
import java.util.List;

public class FileEncryptorGUI extends JFrame {

    private final JTextField inputField;
    private final JTextField outputField;
    private final JPasswordField passwordField;
    private final JButton encryptButton;
    private final JTextArea logArea;

    public FileEncryptorGUI() {
        super("File Encryptor");

        // Initialize components
        inputField = new JTextField(20);
        outputField = new JTextField(20);
        passwordField = new JPasswordField(20);
        encryptButton = new JButton("Encrypt");
        logArea = new JTextArea(10, 30);

        // Add components to content pane
        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());
        contentPane.add(createInputPanel(), BorderLayout.NORTH);
        contentPane.add(new JScrollPane(logArea), BorderLayout.CENTER);

        // Set window properties
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    private JPanel createInputPanel() {
        JPanel inputPanel = new JPanel(new GridBagLayout());

        GridBagConstraints gbc = new GridBagConstraints();
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.anchor = GridBagConstraints.WEST;
        gbc.insets = new Insets(5, 5, 5, 5);
        inputPanel.add(new JLabel("Input file:"), gbc);

        gbc.gridx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        inputPanel.add(inputField, gbc);

        gbc.gridx = 0;
        gbc.gridy = 1;
        gbc.fill = GridBagConstraints.NONE;
        inputPanel.add(new JLabel("Output file:"), gbc);

        gbc.gridx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        inputPanel.add(outputField, gbc);

        gbc.gridx = 0;
        gbc.gridy = 2;
        gbc.fill = GridBagConstraints.NONE;
        inputPanel.add(new JLabel("Password:"), gbc);

        gbc.gridx = 1;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        inputPanel.add(passwordField, gbc);

        gbc.gridx = 0;
        gbc.gridy = 3;
        gbc.gridwidth = 2;
        gbc.fill = GridBagConstraints.NONE;
        gbc.anchor = GridBagConstraints.CENTER;
        inputPanel.add(encryptButton, gbc);

        // Add action listener to encrypt button
        encryptButton.addActionListener(this::encryptFile);

        return inputPanel;
    }

    private void encryptFile(ActionEvent event) {
        // Disable encrypt button
        encryptButton.setEnabled(false);

        // Clear log area
        logArea.setText("");

        // Get input file path, output file path, and password from input fields
        String inputFilePath = inputField.getText();
        String outputFilePath = outputField.getText();
        String password = new String(passwordField.getPassword());

        // Perform file encryption in separate thread
        Thread encryptThread = new Thread(() -> {
            // Read input file
            List<Byte> inputFileBytes = new ArrayList<>();
            try (FileInputStream inputStream = new FileInputStream(inputFilePath)) {
                int byteValue;
                while ((byteValue = inputStream.read()) != -1) {
                    inputFileBytes.add((byte) byteValue);
                }
            } catch (IOException e) {
                logError("Error reading input file: " + e.getMessage());
                return;
            }

            // Encrypt file
            List<Byte> outputFileBytes = new ArrayList<>();
            for (int i = 0; i < inputFileBytes.size(); i++) {

                logMessage(String.format("Encrypted byte %d/%d", i + 1, inputFileBytes.size()));

                // Sleep for 1 second
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    logError("Encryption interrupted: " + e.getMessage());
                    return;
                }
            }

            // Write output file
            try (FileOutputStream outputStream = new FileOutputStream(outputFilePath)) {
                for (Byte outputByte : outputFileBytes) {
                    outputStream.write(outputByte);
                }
                logMessage("Encryption complete!");
            } catch (IOException e) {
                logError("Error writing output file: " + e.getMessage());
                return;
            }

            // Re-enable encrypt button
            encryptButton.setEnabled(true);
        });
        encryptThread.start();
    }

    private void logMessage(String message) {
        logArea.append(message + "\n");
    }

    private void logError(String error) {
        logMessage("Error: " + error);
    }

    public static void main(String[] args) {
        new FileEncryptorGUI();
    }
}

这个程序会创建一个GUI窗口，用户可以在窗口中输入要加密的文件路径、加密后文件的路径和密码。当用户点击“Encrypt”按钮时，程序会在新线程中对文件进行加密，并在GUI窗口中展示加密过程的日志信息，包括每个字节的加密进度和加密完成的消息。在加密过程中，程序会每隔1秒钟暂停一次，以模拟加密过程的延迟。
