从Runnable内部访问线程

Question

How can I access Thread object that is executing given Runnable ? What I'd like to do is to call sleep() from within run() method.

Answer 1

If you need to sleep within a Runnable , you can simply call Thread.sleep(); inside the run method.

To access the thread that is running the Runnable , you can call Thread.currentThread() , but that is not necessary to call the sleep method, which is static.

Answer 2

you can always get the current Thread that your code is executing within by calling the static method Thread.currentThread() .

But in your case, you don't need the thread itself because sleeping is controlled with the following static method:

Thread.sleep(1000L);
