计时器功能中鼠标点击的问题

[dolaqu]

在设计一个计时器功能控件的时候，鼠标单击一次开始计时，再次单击鼠标一次结束，显示出计时结果。然后再单击鼠标一次，计时重新开始，再次单击第二次计时结束。我使用MOUSE_CLICKED来完成。但是怎么控制 单击鼠标后 是运行计时开始呢，还是运行计时结束呢？这个该怎么控制？我是想用个0 1 循环来控制。可不知道该怎么统计单击鼠标的次数。
JDK中有个这样的方法 public int getClickCount()
但是不知道怎么使用。求大侠们帮忙！

我做了一个，你参考一下。

import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

public class FrameTimer extends JFrame implements MouseListener {
	JPanel contentPane;

	JLabel clockLbl;

	BorderLayout borderLayout1 = new BorderLayout();

	long seconds = 0l;

	java.util.Timer timer = null;

	boolean isRunning = false;

	// Construct the frame
	public FrameTimer() {
		enableEvents(AWTEvent.WINDOW_EVENT_MASK);
		try {
			jbInit();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	// Component initialization
	private void jbInit() throws Exception {
		contentPane = (JPanel) this.getContentPane();
		contentPane.setLayout(borderLayout1);
		this.setSize(new Dimension(100, 100));
		this.setTitle("Frame Timer");
		clockLbl = new JLabel();
		contentPane.add(clockLbl, BorderLayout.CENTER);
		this.addMouseListener(this);
		showClock();
	}

	// Overridden so we can exit when window is closed
	protected void processWindowEvent(WindowEvent e) {
		super.processWindowEvent(e);
		if (e.getID() == WindowEvent.WINDOW_CLOSING) {
			System.exit(0);
		}
	}

	private void showClock() {
		long tHours = seconds / 60 / 60;
		long tMintus = (seconds % (60 * 60)) / 60;
		long tSecons = (seconds % (60 * 60)) % 60;
		String clockText = (tHours > 10 ? "" + tHours : "0" + tHours) + ":"
				+ (tMintus > 10 ? "" + tMintus : "0" + tMintus) + ":"
				+ (tSecons > 10 ? "" + tSecons : "0" + tSecons);
		clockLbl.setText(clockText);
	}

	private void clock() {
		seconds++;
		showClock();
	}

	public static void main(String[] args) {
		(new FrameTimer()).setVisible(true);
	}

	static class Job extends java.util.TimerTask {

		FrameTimer timer;

		public Job(FrameTimer timer) {
			this.timer = timer;
		}

		@Override
		public void run() {
			timer.clock();
		}
	}

	public void mouseClicked(MouseEvent e) {
		if (e.getClickCount() == 1) {
			if (seconds == 0) {
				timer = new java.util.Timer();
				timer.schedule(new Job(this), 0, 1000);
				isRunning = true;
			} else if (isRunning) {
				isRunning = false;
				timer.cancel();
			} else {
				timer = null;
				seconds = 0;
				showClock();
			}
		}
	}

	public void mouseEntered(MouseEvent e) {
	}

	public void mouseExited(MouseEvent e) {
	}

	public void mousePressed(MouseEvent e) {
	}

	public void mouseReleased(MouseEvent e) {
	}
}
