From different classes, sleep and yield come from Thread class, and wait and notify come from Object class.

Whether or not to release the lock, sleep does not release the lock, and wait releases the lock so that other threads can execute synchronous blocks or methods. Sleep does not transfer system resources, wait enters the thread waiting pool to wait, and transfers resources.

Scope of use, wait, notify can only be used in synchronization control methods or synchronization control blocks, while sleep can be used anywhere.
