What is the purpose of sleep () and join () methods in Java?

To pause the current executing thread for giving the chance of remaining threads of same priority. If a thread wants to wait until completing thread some other threads, then we should go for join. If a thread doesn’t want to perform any operation for a particular amount of time, then we should go for sleep() method.

What is difference between join and wait in Java?

Differences between wait() and join() methods in Java The wait() and join() methods are used to pause the current thread. The wait() is used in with notify() and notifyAll() methods, but join() is used in Java to wait until one thread finishes its execution. On the other hand join() is used for waiting a thread to die.

What is difference between wait () and sleep () method?

What is join method in Java?

Thread class provides the join() method which allows one thread to wait until another thread completes its execution. If t is a Thread object whose thread is currently executing, then t. join() will make sure that t is terminated before the next instruction is executed by the program.

Why sleep method is static?

The code would only execute when someXThread was executing, in which case telling someYThread to yield would be pointless. So since the only thread worth calling yield on is the current thread, they make the method static so you won’t waste time trying to call yield on some other thread.
