求java的计时器代码，应该比较简单的，来看看吧。

pan.add(btnPouse);

pan.add(new Label());
add(pan);
btnGo.addActionListener(new btnGoListener());
btnReset.addActionListener(new btnResetListener());
btnPouse.addActionListener(new btnPouseListener());
swThread.setDaemon(true);
swThread.start();
}
public static void main(String[] args) {
Test5 applet = new Test5();
Frame aFrame = new Frame("计时器");
aFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
aFrame.add(applet, BorderLayout.CENTER);
aFrame.setSize(400, 200);
applet.init();
applet.start();
aFrame.setVisible(true);
}
}
可以改变有注释的那个if语句里面的值来判断什么时候停止

Q1: Java怎么给方法计时？
你可以在开始和结束的时候，分别记录下当前的时间的这毫秒数。然后再减，以下是一段代码。\x0d\x0a\x0d\x0apublicclassTest{\x0d\x0apublicstaticvoidmain(String[]args){\x0d\x0alongstartMili=System.currentTimeMillis();//当前时间对应的毫秒数\x0d\x0aSystem.out.println("开始"+startMili);\x0d\x0a//执行一段代码,求一百万次随机值\x0d\x0afor(inti=0;i

Q2: java连连看里设置150秒倒计时，重行开始游戏时时间再次从150秒开始倒计时的代码怎么写，急！！！！！！！
参考一下吧。
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;

private TimeThread tt = null;
private boolean ttFlag = false;
private void init() {
final JLabel tip = new JLabel();
final JButton start = new JButton("开始");
final JButton end = new JButton("结束");
JFrame f = new JFrame();
f.setLayout(new FlowLayout(5));
f.add(tip);
f.add(start);
f.add(end);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
f.setSize(300, 150);
f.setLocationRelativeTo(null);
start.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
start.setEnabled(false);
tip.setFont(new Font("宋体",Font.BOLD,27));
ttFlag = true;
tt = new TimeThread(tip);
tt.start();
}
});
end.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
start.setEnabled(true);
tip.setText("");
Program.seconds = 150;
ttFlag = false;
}
});
}
/**

*/
public static void main(String[] args) {
new Program().init();
}
class TimeThread extends Thread {
private JLabel tip;
TimeThread(JLabel tip) {
this.tip = tip;
}
@Override
public void run() {
int seconds = Program.seconds;
tip.setText(seconds+"");
while (seconds-- 0 ttFlag) {
tip.setText(seconds+"");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
};
}
