JAVA test_windowClosing

一个可以点击右上角“X"可以关闭的界面。写的时候因为windowClosing写成了windouClosing一直出问题。

import java.awt.*;import java.awt.event.WindowAdapter;import java.awt.event.WindowEvent;public class Main {public static void main(String[] args) {new MyFrame("test_windowClosing");}}class MyFrame extends Frame {MyFrame(String s) {super(s);setBounds(100, 100, 300, 300);setBackground(Color.BLUE);setVisible(true);this.addWindowListener(new WindowAdapter() {public void windowClosing(WindowEvent e) {setVisible(false);System.exit(0);}});}}
