java停止线程的方式

1、使用Interrupt来通知

while(!Thread.currentThread().isInterrupted()&&moreworktodo){domorework}

首先通过 Thread.currentThread().isInterrupt() 判断线程是否被中断，随后检查是否还有工作要做。

publicclassStopThreadimplementsRunnable{

@Override
publicvoidrun(){

intcount=0;

while(!Thread.currentThread().isInterrupted()&&count<1000){

System.out.println("count="+count++);

}

}

publicstaticvoidmain(String[]args)throwsInterruptedException{

Threadthread=newThread(newStopThread());
thread.start();
Thread.sleep(5);
thread.interrupt();
}

}

2、使用volatile标志一个字段，通过判断这个字段true/false退出线程

/**
*描述：演示用volatile的局限：part1看似可行
*/
publicclassWrongWayVolatileimplementsRunnable{

privatevolatilebooleancanceled=false;

@Override
publicvoidrun(){
intnum=0;
try{
while(num<=100000&&!canceled){
if(num%100==0){
System.out.println(num+"是100的倍数。");
}
num++;
Thread.sleep(1);
}
}catch(InterruptedExceptione){
e.printStackTrace();
}
}

publicstaticvoidmain(String[]args)throwsInterruptedException{
WrongWayVolatiler=newWrongWayVolatile();
Threadthread=newThread(r);
thread.start();
Thread.sleep(5000);
r.canceled=true;
}
}

以上就是java停止线程的方式，希望对大家有所帮助。更多Java学习指路：Java基础
