阻止其他线程运行一段代码
我想阻止其他线程（非法线程）运行run()。解决方案是：
public class MyThread extends Thread {
public void run() {
if (currentThread() != this)
throw new IllegalStateException("Exception occurred by: " + currentThread().toString());
/* Here goes the main logic of thread */
}
}
当MyThread类直接实现Runnable时，我们如何做同样的事情？
I want to prevent to other threads(illegal threads) from running run(). the solution is:
public class MyThread extends Thread {
public void run() {
if (currentThread() != this)
throw new IllegalStateException("Exception occurred by: " + currentThread().toString());
/* Here goes the main logic of thread */
}
}
How could we do the same thing when MyThread class is directly implementing Runnable?

只需存储对
Thread的引用，该线程允许作为Runnable类中的成员运行代码。在比较中使用它。Simply store a reference to the
Threadthat is allowed to run the code as a member in yourRunnableclass. Use that in the comparison.
