java swing 冒泡排序 实时 显示 演示

好的，我可以为您演示一个 Java Swing 冒泡排序实时显示的程序。以下是程序的代码：

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

public class BubbleSortVisualizer extends JFrame {
    private static final long serialVersionUID = 1L;
    private JPanel panel;
    private JButton button;
    private JTextField textField;
    private int[] array = { 5, 3, 1, 2, 4 };
    private int delay = 500;

    public BubbleSortVisualizer() {
        setTitle("Bubble Sort Visualizer");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 200);
        setLocationRelativeTo(null);
        setResizable(false);

        panel = new JPanel();
        panel.setLayout(new BorderLayout());
        add(panel);

        JPanel topPanel = new JPanel();
        topPanel.setLayout(new FlowLayout());
        panel.add(topPanel, BorderLayout.NORTH);

        JLabel label = new JLabel("Array: ");
        topPanel.add(label);

        textField = new JTextField(20);
        textField.setEditable(false);
        topPanel.add(textField);

        JPanel bottomPanel = new JPanel();
        bottomPanel.setLayout(new FlowLayout());
        panel.add(bottomPanel, BorderLayout.SOUTH);

        button = new JButton("Sort");
        bottomPanel.add(button);

        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                Thread thread = new Thread(new Runnable() {
                    public void run() {
                        bubbleSort();
                    }
                });
                thread.start();
            }
        });

        setVisible(true);
    }

    private void bubbleSort() {
        for (int i = 0; i < array.length - 1; i++) {
            for (int j = 0; j < array.length - i - 1; j++) {
                if (array[j] > array[j + 1]) {
                    int temp = array[j];
                    array[j] = array[j + 1];
                    array[j + 1] = temp;
                    updateTextField();
                    sleep();
                }
            }
        }
    }

    private void updateTextField() {
        StringBuilder stringBuilder = new StringBuilder();
        for (int i = 0; i < array.length; i++) {
            stringBuilder.append(array[i]);
            if (i != array.length - 1) {
                stringBuilder.append(", ");
            }
        }
        textField.setText(stringBuilder.toString());
    }

    private void sleep() {
        try {
            Thread.sleep(delay);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

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

运行程序后，您可以在窗口中看到一个文本框和一个“Sort”按钮。文本框显示了初始数组的值（即 `5, 3, 1, 2, 4`）。当您点击“Sort”按钮时，程序将开始使用冒泡排序对数组进行排序，并在每次交换时更新文本框中的值，以实现实时演示。程序默认的延迟时间为 500 毫秒，您可以根据需要更改此值。
