PostHeaderIcon Difference between wait() and sleep() in Java

Today in interview I have also been asked the following question: in Java, what is the difference between the methods wait() and sleep()?

First of all, wait() is a method of Object, meanwhile sleep() is a static method of Thread.

More important: Thread.sleep() freezes the execution of the complete thread for a given time. wait(), on its side, gives a maximum time on which the application is suspended: the waiting period may be interrupted by a call to the method notify() on the same object.
