关于一个多线程的码表问题

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

class MyThread extends Thread {
	private JLabel label;
	private long time;
	private long endtime;

	public MyThread(JLabel label, long time) {
		this.label = label;
		this.time = time;
	}

	public void init() {
		endtime = System.currentTimeMillis() + time;
	}

	@Override
	public void run() {		
		init();
		while (true) {
			long runtime = endtime - System.currentTimeMillis();
			time = runtime;
			if(runtime > 0){
				label.setText(formatTime(runtime));
			}else{
				label.setText("GAME OVER");
			}

			try {
				Thread.sleep(10);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}

	private String formatTime(long runtime) {
		int m = (int) (runtime / 1000 / 60);
		int s = (int) (runtime / 1000 % 60);
		int ss = (int) (runtime % 1000);
		return check(m) + ":" + check(s) + "." + check(ss);
	}

	private String check(int number) {
		return number > 9 ? "" + number : "0" + number;
	}
}

class ClockFrame extends JFrame {
	private JLabel label;
	private JButton button;
	private MyThread mt;
	private boolean bFlag = true;// 控制按钮的显示及线程的挂起恢复

	public ClockFrame() {
		label = new JLabel();
		label.setHorizontalAlignment(JLabel.CENTER);
		add(label, BorderLayout.CENTER);

		button = new JButton("暂停");
		add(button, BorderLayout.NORTH);
		setBounds(222, 222, 222, 222);
		setVisible(true);

		mt = new MyThread(label, 10000L);
		mt.start();

		button.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				if (bFlag) {
					button.setText("继续");
					mt.suspend();
				} else {
					button.setText("暂停");
					mt.init();
					mt.resume();
				}
				bFlag = !bFlag;
			}
		});

	}
}

public class ClockTest {
	public static void main(String[] args) {
		new ClockFrame();
	}
}

以上是一个多线程的码表程序,运行起来没有问题,但是用到了两个过时的方法,suspend,suspend,想请问如果用wait, notify这两个方法,应该怎么改这个程序,谢谢
