java.lang.Thread.isInterrupted() 方法测试该线程是否已被中断。线程的中断状态不受该方法影响。

因为一个线程不是活在中断的时间线中断将被忽略，通过此方法来返回false。

声明

以下是java.lang.Thread.isInterrupted()方法的声明

public boolean isInterrupted()

参数

• NA

返回值

如果该线程已经中断此方法返回true;否则为false。

异常

• NA

例子

下面的例子显示java.lang.Thread.isInterrupted()方法的使用。

package com.yiibai;

import java.lang.*;

public class ThreadDemo implements Runnable {

   Thread t;

   ThreadDemo() {

      t = new Thread(this);
      System.out.println("Executing " + t.getName());
      // this will call run() fucntion
      t.start();
        
      // tests whether this thread has been interrupted
      if (!t.isInterrupted()) {
         t.interrupt();
      }
      // block until other threads finish
      try {  
         t.join();
      } catch(InterruptedException e) {}
   }

   public void run() {
      try {       
         while (true) {
            Thread.sleep(1000);
         }
      } catch (InterruptedException e) {
           System.out.print(t.getName() + " interrupted:");
           System.out.println(e.toString());
        }
   }

   public static void main(String args[]) {
     new ThreadDemo();
     new ThreadDemo();
   }
} 

让我们来编译和运行上面的程序，这将产生以下结果：

Executing Thread-0
Thread-0 interrupted:java.lang.InterruptedException: sleep interrupted
Executing Thread-1
Thread-1 interrupted:java.lang.InterruptedException: sleep interrupted
