How do you suspend thread?

Answer 1

Once a thread begins executing its run() method, it continues execution until the run() method completes. If you're familiar with other thread models, you may know of a concept called thread suspension, where a thread is told to pause its execution. Later, the thread is resumed, which is to say that it is told to continue its execution. The Thread class contains suspend() and resume() methods, but they suffer from the same race condition problem as the stop() method, and they, too, are deprecated.

It is possible for a thread to suspend its own execution for a specific period of time by calling the sleep() method. When a thread executes the sleep() method, it pauses for a given number of milliseconds, during which it is said to be asleep. When the pause time has elapsed, the thread wakes up and continues execution with the statements immediately following the sleep() method.
