What is wait () in Java?
Simply put, wait() is an instance method that’s used for thread synchronization. It can be called on any object, as it’s defined right on java. lang. Object, but it can only be called from a synchronized block. It releases the lock on the object so that another thread can jump in and acquire a lock.

ScheduledThreadPoolExecutor class in Java is a subclass of ThreadPoolExecutor class defined in java. util. concurrent package.

What is notify () in Java?
notify() wakes up a single thread that is waiting on this object’s monitor. By executing a synchronized instance method of that object. By executing the body of a synchronized statement that synchronizes on the object. For objects of type Class, by executing a synchronized static method of that class.
Can we override static method?
Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism.
