In Java, both the `wait()` and `sleep()` methods are used in multithreading, but they serve different purposes and behave differently:

1. *wait():*
`wait()` is a method defined in the `Object` class and is used for inter-thread communication and synchronization.
When a thread calls `wait()` on an object, it releases the lock on that object and enters into a waiting state until another thread invokes the `notify()` or `notifyAll()` method on the same object.
`wait()` must be called from within a synchronized block or method.

2. *sleep():*
`sleep()` is a static method defined in the `Thread` class and is used to pause the execution of a thread for a specified amount of time.
When a thread calls `sleep()`, it does not release any locks it might have acquired.
Unlike `wait()`, `sleep()` does not require synchronization.

*Key Differences:*
Purpose: `wait()` is used for thread synchronization and inter-thread communication, while `sleep()` is used for pausing the execution of a thread.
Lock Release: `wait()` releases the lock on the object it is called on, while `sleep()` does not release any locks.
Invocation: `wait()` must be called from within a synchronized block or method, while `sleep()` can be called from anywhere in the code.
