小问题,要线等.
package   com;
import   java.util.*;

public   class   Alert   {
Timer   timer;
public   Alert(){
timer=new   Timer();
timer.schedule(new   RemindTask(),0,1*1000);
}


public   static   void   main(String[]   args)   {
//   TODO   Auto-generated   method   stub
new   Alert();

}

}
package   com;

import   java.util.TimerTask;


public   class   RemindTask1   extends   TimerTask   {
int   numWarning=5;
public   void   run()   {

if(numWarning==5){
System.out.println( "Alert! ");
numWarning--;
}
else{
System.out.println( "Time 's   up! ");//怎么是执行这行的?
System.exit(0);
}


}

}


运行结果:
Time 's   up!
怎么结果不是这个:
Alert!
Alert!
Alert!
Alert!
Alert!
高手请教,谢谢!
