线程中断:

/**

*/
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。

线程优先级:

/**

*/
public class Test4Thread3 { public static void main(String[] args) {
MyT1 myT1 = new MyT1();
Thread t2_1 = new Thread(myT1,"myT1_1");
Thread t2_2 = new Thread(myT1,"myT1_2");
Thread t2_3 = new Thread(myT1,"myT1_3");
t2_1.setPriority(1);
t2_2.setPriority(10);
t2_3.setPriority(1);
t2_1.start();
t2_2.start();
t2_3.start();
} } class MyT1 implements Runnable {
int tickets = 10; public void run() {
for (; tickets > 0; ) {
System.out.println(Thread.currentThread().getName() + ":" + tickets--);
}
}
}

结果:

myT1_2:10

myT1_1:7
myT1_2:8
myT1_2:4
myT1_2:3
myT1_2:2
