第一次写java的小游戏

想实现点击右下角的暂停 实现游戏的暂停和继续 不知道该怎么加，自己找了线程的内容但试了还是成功不了，求大佬们帮一下小白。代码有点乱，大佬们见谅。，，

TypingGame文件：

import javax.swing.JFrame;public class TypingGame {

public static void main(String[] args) {

JFrame frame = new JFrame();

TypingGamePanel panel = new TypingGamePanel();

frame.add(panel);

Thread t = new Thread(panel);

t.start();

panel.addKeyListener(panel);

panel.setFocusable(true);

panel.addMouseListener(panel);

frame.setSize(1500, 900);

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );

frame.setVisible(true);

}}
