Q2: 写一个计时器 JAVA代码是什么？
应该用线程里面的Timer来控制package com.sy.game.test;
import java.util.Timer;
import java.util.TimerTask;
public class TimeTask {
public static void main(String[] args) {
TimeTask tTask=new TimeTask();
tTask.timeVoid();
}
public void timeVoid(){
final Timer timer = new Timer();
TimerTask tt=new TimerTask() {
@Override
public void run() {
System.out.println("到点啦!");
timer.cancel();
}
};
timer.schedule(tt, 3000);
}
}
整合的：

Q4: 怎么编写一个倒计时的java的程序？求具体步骤！
基于控制台java分秒倒计时代码的话很简单的java分秒倒计时代码，java分秒倒计时代码我跟java分秒倒计时代码你说一下大体思路吧，二话不说先来个for循环，然后输出倒计时的数字，程序睡一秒，在输出倒计时数字，如此循环，简单吧，下面看程序：
public static void main(String[] args) {
for(int i=10;i0;i--){
System.out.print(i+" ");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.err.print("爆炸");
}
其他基于网页的还是基于用户界面都可以使用这个思路的
