[解决办法]
Thread.sleep(3000);
[解决办法]
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run()
{
MainProcess();
}
},0,1*3000);
這個可以!
[解决办法]
Timer timer = new Timer();
timer.scheduleAtFixedRate(notetimer, 1000, 1000 * 3);
[解决办法]
一楼
Thread.sleep(3000);
[解决办法]
java.util.Timer tmr = new java.util.Timer();
java.util.GregorianCalendar now = null;
tmr.schedule(new java.util.TimerTask(){
public void run(){
now = new GregorianCalendar();
//do something
}
},now.getTime(),3000);

怎么来求人帮忙还这么多牢骚 现在的人都怎么了
[解决办法]
这么长的代码谁看呀
[解决办法]
写的乱点，上面好多正解，楼主不采用，那也没法啊！！！
[解决办法]
就是,代码又长,又乱,你叫你怎么帮你看啊,写代码,一定要规范.要不我找几千行代码,叫你先帮我看看,看你会有什么感受,整个上下,注释都没有.一楼的叫你用线程,那是一种不错的解决方法.
还在那说没人看你代码.郁闷......
[解决办法]
没看代码，你的那个this是什么？如果不四、是TimerTask就是不行的，你查查Timer 的api 构造方法
