1、说明
isInterrupted()可以判断当前线程是否被中断，仅仅是对interrupt()标识的一个判断，并不会影响标识发生任何改变（因为调用interrupt()的时候会设置内部的一个叫interrupt flag的标识）。
2、实例
public static void main(String[] args) throws InterruptedException{
Thread thread = new Thread(()->{
while (true){}
});
thread.start();
TimeUnit.SECONDS.sleep(1);
System.out.println("Thread is interrupted :"+thread.isInterrupted());
thread.interrupt();
System.out.println("Thread is interrupted :"+thread.isInterrupted());
}实例扩展补充：
ublic class t12 {
public static void main(String[] args) {
try {
MyThread12 thread = new MyThread12();
thread.start();
Thread.sleep(500);
thread.interrupt();
System.out.println("是否终止1？ =" + thread.interrupted());
System.out.println("是否终止2？ =" + thread.interrupted());
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("-------------end-------------");
}
}
class MyThread12 extends Thread {
public void run() {
for (int i = 0; i < 50000; i++) {
System.out.println("i = " + i);
}
}
