为什么Thread.sleep(50)休眠的就是舞台线程而不是其他的？
public void run(){
ArmyRunnable armySuiDynasty = new ArmyRunnable();
ArmyRunnable armyRevolt = new ArmyRunnable();
//使用Runnable接口创建线程
Thread armyOfSuiDynasty = new Thread(armySuiDynasty,"隋军");
Thread armyOfRevolt = new Thread(armyRevolt,"隋军");
//启动线程，让军队开始作战
armyOfSuiDynasty.start();
armyOfRevolt.start();
//舞台线程休眠，大家专心观看军队的弑杀
try {
Thread.sleep(50);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
