编写代码 TestActionEvent测试类
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");
// 因为addActionListener 需要一个 ActionListener ,所以就构造了一个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);
}
//关闭窗体事件
private static void WindowClose(Frame frame) {
frame.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
// ActionListener 事件监听
class MyActionListener implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
System.out.println("MyActionListener");
}
};
运行结果
