編寫程式碼 TestActionEvent測試類

package com.xiang.lesson02;

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestActionEvent {
    public static void main(String[] args) {
        Frame frame = new Frame();
        Button button = new Button("btn1");

//        因為addActionListener 需要一個  ActionListener ，所以就構造了一個ActionListener
        MyActionListener listener = new MyActionListener();
        button.addActionListener(listener);

        frame.add(button, BorderLayout.CENTER);

        frame.setVisible(true);
        frame.setBounds(400, 400, 400, 400);
        frame.setBackground(Color.yellow);
        WindowClose(frame);
    }

    //關閉窗體事件
    private static void WindowClose(Frame frame) {
        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }
}

// ActionListener 事件監聽
class MyActionListener implements ActionListener {

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("MyActionListener");
    }
};
