Thread.interrupted & Thread.curr

源码：

Thread.interrupted

public static boolean interrupted() {

return currentThread().isInterrupted(true);

}

Thread.currentThread().isInterrupted()：

public boolean isInterrupted() {

return isInterrupted(false);

}

最后调用底层，从参数名可以看出，interrupted静态方法会擦出线程的中断标志，而Thread.currentThread().isInterrupted()不会执行擦除。

private native boolean isInterrupted(boolean ClearInterrupted);

代码验证：

//输出当前线程的中断标志

System.out.println(Thread.currentThread().isInterrupted());

//标记中断

Thread.currentThread().interrupt();

//输出当前线程的中断标志

System.out.println(Thread.currentThread().isInterrupted());

//输出当前线程中断标志并擦除

System.out.println(Thread.interrupted());

//再次输出当前线程的中断标志

System.out.println(Thread.currentThread().isInterrupted());

结果输出：

false

true

true

false
