1、使用Interrupt来通知
1 | while (!Thread.currentThread().isInterrupted() && more work to do ) { do more work }
|
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。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | public class StopThread implements Runnable {
@Override
public void run() {
int count = 0;
while (!Thread.currentThread().isInterrupted() && count < 1000) {
System.out.println( "count = " + count++);
}
}
public static void main(String[] args) throws InterruptedException {
Thread thread = new Thread( new StopThread());
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
public class WrongWayVolatile implements Runnable {
private volatile boolean canceled = false ;
@Override
public void run() {
int num = 0;
try {
while (num <= 100000 && !canceled) {
if (num % 100 == 0) {
System.out.println(num + "是100的倍数。" );
}
num++;
Thread.sleep(1);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws InterruptedException {
WrongWayVolatile r = new WrongWayVolatile();
Thread thread = new Thread(r);
thread.start();
Thread.sleep(5000);
r.canceled = true ;
}
}
