1、使用Interrupt來通知
while (!Thread.currentThread().isInterrupted() && more work to do) { do more work }先透過 Thread.currentThread().isInterrupt() 判斷執行緒是否被中斷，然後檢查是否還有工作要做。
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標誌一個字段，透過判斷這個字段true/false退出線程
/**
* 描述： 演示用volatile的局限：part1 看似可行
*/
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;
}
}以上是java怎麼停止線程的詳細內容。更多資訊請關注PHP中文網其他相關文章！
