Sleep is method from Thread class. This can be called without object and will act on current running thread.
Calling sleep on current thread will throw InterruptedException that you need to handle in your code.
When a thread goes to sleep, it does not release it's resources then and there because after certain time it will awake and need those resources.

public void run() {
System.out.println("Thread going to sleep :- " + Thread.currentThread().getName());
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Thread wakenup is :- " + Thread.currentThread().getName());
}
}
public class SleepExample {
public static void main(String[] args) {
Thread t1 = new Thread(new MyRunnable(),"Bruno");
Thread t2 = new Thread(new MyRunnable(),"Adam");
t1.start();
t2.start();
}
}
Output will be :-
Thread going to sleep :- Bruno Thread going to sleep :- Adam Thread wakenup is :- Adam Thread wakenup is :- Bruno
