如何遍历按钮并在Java中禁用它们？

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

public class DisableButtonsExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Disable Buttons Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        // 创建一个面板并添加按钮
        JPanel panel = new JPanel();
        panel.setLayout(new FlowLayout());
        panel.add(new JButton("Button 1"));
        panel.add(new JButton("Button 2"));
        panel.add(new JButton("Button 3"));
        
        // 遍历面板中的组件并禁用按钮
        Component[] components = panel.getComponents();
        for (Component component : components) {
            if (component instanceof JButton) {
                JButton button = (JButton) component;
                button.setEnabled(false);
            }
        }
        
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }
}
