java.lang.Thread.isInterrupted() 方法測試該線程是否已被中斷。線程的中斷狀態不受該方法影響。

因為一個線程不是活在中斷的時間線中斷將被忽略，通過此方法來返回false。

聲明

以下是java.lang.Thread.isInterrupted()方法的聲明

public boolean isInterrupted()

參數

• NA

返回值

如果該線程已經中斷此方法返回true;否則為false。

異常

• NA

例子

下麵的例子顯示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();
   }
} 

讓我們來編譯和運行上麵的程序，這將產生以下結果：

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