Difference Between Sleep And Wait In Java
In Java, the main difference between sleep() and wait() methods lies in their purpose and usage. The sleep() method is used to pause the execution of the current thread for a specified amount of time, without releasing any locks held by the thread. On the other hand, the wait() method is used for communication between threads and is called on an object's monitor. When a thread invokes wait(), it releases the lock it holds, allowing other threads to execute, and waits until another thread calls notify() or notifyAll() on the same object to resume its execution. Overall, sleep() is used for delaying execution for a specified time while wait() is used for thread synchronization and inter-thread communication.

1 - In Java, one key difference between sleep and wait is the context in which they are used.
2) The sleep method belongs to the Thread class and is used to pause the execution of a particular thread for a specified amount of time.
3) On the other hand, the wait method is called on an object and is used for inter thread communication in a multi threaded environment.
4) When a thread calls sleep, it is simply put on hold for the specified time duration without releasing any locks it may hold.
5) In contrast, when a thread invokes wait on an object, it releases the lock associated with that object and enters a waiting state until another thread notifies or interrupts it.
6) The sleep method is generally used for introducing delays or when a thread needs to pause for a specific period of time.
7) The wait method, however, is used in scenarios where threads need to coordinate with each other and synchronize their actions.
8) Another difference is that sleep is a static method in the Thread class, while wait is an instance method that is called on an object.
9) Sleep is straightforward to use as it simply takes a time parameter, whereas wait must be enclosed within a synchronized block and is always used in conjunction with notify/notifyAll methods for proper synchronization.
10) It's important to note that while sleep is a method provided by the language itself, wait is a concept of thread synchronization supported by Java.
