线程中断:
/** * Created by root on 17-9-30. */ public class Test4Thread2 { public static void main(String[] args) { Thread t=new Thread(()->{try { System.out.println(Thread.currentThread().getName()+"start"); Thread.sleep(10000); System.out.println(Thread.currentThread().getName()+"end"); } catch (InterruptedException e) { e.printStackTrace(); }}); t.start(); Thread t2=new Thread(()->{try { for (int i=0;i<10;i++){ Thread.sleep(1000); System.out.println(Thread.currentThread().getName()+">>>"+i); if (i==3){ t.interrupt(); } } } catch (InterruptedException e) { e.printStackTrace(); }}); t2.start(); } }
输出:
Thread-0start Thread-1>>>0 Thread-1>>>1 Thread-1>>>2 Thread-1>>>3 java.lang.InterruptedException: sleep interrupted at java.lang.Thread.sleep(Native Method) at com.xh.alibaba.Test4Thread2.lambda$main$0(Test4Thread2.java:11) at java.lang.Thread.run(Thread.java:745) Thread-1>>>4 Thread-1>>>5 Thread-1>>>6 Thread-1>>>7 Thread-1>>>8 Thread-1>>>9 Process finished with exit code 0
当线程0在休眠时,线程1打断他,就会报异常。
