多线程:线程终止

线程终止

interrupt()设置线程中断标志，默认值为False

（无法打断该线程的执行，但是可以获得该线程被中断的标志,interrupted()得到true, 判断中断）标志决定是否要终止线程。

MyThread.java

package test5;

public class MyThread extends Thread {
	String name;

	public MyThread(String name) {
		super();
		this.name = name;
	}
	public void run() {
		System.out.println("线程"+this.name+"开始执行");
		int i=0;
		while(1==1) {
			if(!Thread.currentThread().isInterrupted()) {
				System.out.println(i);
				i++;
			}else {
				System.out.println("执行结束");
				return;
			}
		}
	}
}

text.java

package test5;

public class test {

	public static void main(String[] args) throws InterruptedException {
		MyThread mt1=new MyThread("123");
		System.out.println("设置终止前:"+mt1.isInterrupted());
		mt1.start();
		//10ms后将线程mt1的执行标准设置为ture
		Thread.sleep(1);
	    mt1.interrupt();
		
		System.out.println("设置终止后:"+mt1.isInterrupted());
	}
}

执行结果:

设置终止前:false
线程123开始执行
0
1

3
..
...
....
218
219
220
执行结束
设置终止后:true
