A sleeping thread passes time doing nothing and without using the CPU.
sleep(), like yield(), is static. Both methods operate on the currently executing thread.
public class MainClass{
public static void main(String[] argv) throws Exception{
Thread.sleep(1000);
}
}
When a thread goes to sleep, its locks will be unavailable to other threads.
Sleeping is used to delay execution for a period of time.
No locks are released when a thread goes to sleep.
A sleeping thread is guaranteed to sleep for at least the time specified
There is no guarantee when the awakened thread will return to running.
The sleep() method is a static method that sleeps the currently executing thread's state.
One thread cannot tell another thread to sleep.
