使用java编写一个有界面的进制互相转换应用程序在windows上使用

以下是使用Java Swing编写的一个简单的进制转换应用程序。该应用程序可以将二进制、八进制、十进制和十六进制之间进行转换，并提供了一个简单的用户界面。

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

public class NumberConverter extends JFrame implements ActionListener {
    private JTextField inputField, outputField;
    private JButton binButton, octButton, decButton, hexButton;

    public NumberConverter() {
        super("Number Converter");

        // Create input field
        inputField = new JTextField();
        inputField.addActionListener(this);

        // Create output field
        outputField = new JTextField();
        outputField.setEditable(false);

        // Create buttons
        binButton = new JButton("Bin");
        binButton.addActionListener(this);
        octButton = new JButton("Oct");
        octButton.addActionListener(this);
        decButton = new JButton("Dec");
        decButton.addActionListener(this);
        hexButton = new JButton("Hex");
        hexButton.addActionListener(this);

        // Create layout
        JPanel contentPane = new JPanel(new BorderLayout());
        JPanel inputPanel = new JPanel(new BorderLayout());
        inputPanel.add(new JLabel("Enter number: "), BorderLayout.WEST);
        inputPanel.add(inputField, BorderLayout.CENTER);
        contentPane.add(inputPanel, BorderLayout.NORTH);
        JPanel buttonPanel = new JPanel(new GridLayout(1, 4));
        buttonPanel.add(binButton);
        buttonPanel.add(octButton);
        buttonPanel.add(decButton);
        buttonPanel.add(hexButton);
        contentPane.add(buttonPanel, BorderLayout.CENTER);
        JPanel outputPanel = new JPanel(new BorderLayout());
        outputPanel.add(new JLabel("Result: "), BorderLayout.WEST);
        outputPanel.add(outputField, BorderLayout.CENTER);
        contentPane.add(outputPanel, BorderLayout.SOUTH);
        setContentPane(contentPane);

        // Set window properties
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 100);
        setResizable(false);
        setLocationRelativeTo(null);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        try {
            String input = inputField.getText();
            if (e.getSource() == binButton) {
                outputField.setText(Integer.parseInt(input, 2) + "");
            } else if (e.getSource() == octButton) {
                outputField.setText(Integer.parseInt(input, 8) + "");
            } else if (e.getSource() == decButton) {
                outputField.setText(Integer.parseInt(input, 10) + "");
            } else if (e.getSource() == hexButton) {
                outputField.setText(Integer.parseInt(input, 16) + "");
            } else {
                outputField.setText("");
            }
        } catch (NumberFormatException ex) {
            outputField.setText("Invalid input");
        }
    }

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

运行该程序后，将会看到一个简单的窗口，用户可以在其中输入数字并将其转换为二进制、八进制、十进制或十六进制。例如，输入十进制数字“42”，按下“Hex”按钮，将会显示十六进制数字“2A”。
