(Java)使用ActionListeners创建多(26)个按钮，无需重复代码

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

public class MultipleButtonsExample extends JFrame {
    public MultipleButtonsExample() {
        setTitle("Multiple Buttons Example");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new FlowLayout());

        // 创建26个按钮
        for (char c = 'A'; c <= 'Z'; c++) {
            JButton button = new JButton(String.valueOf(c));
            button.addActionListener(new ButtonClickListener());
            add(button);
        }

        pack();
        setVisible(true);
    }

    private class ButtonClickListener implements ActionListener {
        @Override
        public void actionPerformed(ActionEvent e) {
            JButton source = (JButton) e.getSource();
            String buttonText = source.getText();
            System.out.println("Button " + buttonText + " clicked.");
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> new MultipleButtonsExample());
    }
}
