在Thread类中重写Interrupt&isInterrupted

Question

public class MyThread extends Thread {

    private boolean isInterrupted = false;

    @Override 
    public void interrupt() {
        isInterrupted = true;
        super.interrupt();
    }

    @Override
    public boolean isInterrupted() {
        return isInterrupted;
    }

    public void run() {
        .........
        .........

        try {
            object1.wait();
        } catch (InterruptedException e) {
            /* if interrput() is not overrided, the interrupted flag 
            would be reset */
        }

        if(Thread.currentThread().isInterrupted()) {
            /* if interrupt is not overrided, isInterrupted would return
            false and the thread would continue to run. */
            return;
        }

        object2.method1(); // method1() can also wait on another object
        /* In method1() also we would need to check isInterrupted and get out
        quickly as soon as possible. This method1() will also be used by
        other threads which will not be interrupted. */

        if(Thread.currentThread().isInterrupted()) {
            return;
        }
        .........
        .........
    }
}

首先，重写这些方法是一个非常糟糕的主意。

第二，我不明白你为什么让你的生活如此艰难：

try {
  doSomethingThatCanBlock();// e.g. wait()
}
catch(InterruptedException ex) {
  Thread.currentThread().interrupt(); // restore interrupt state
}

现在，下次检查线程的中断状态时，它将告诉您适当的状态。就是这样。
