What is destructor example?

In Java, the garbage collector automatically deletes the unused objects to free up the memory. Developers have no need to mark the objects for deletion, which is error-prone and vulnerable to the memory leak. So it’s sensible Java has no destructors available .

A destructor is a member function that is invoked automatically when the object goes out of scope or is explicitly destroyed by a call to delete . A destructor has the same name as the class, preceded by a tilde ( ~ ). For example, the destructor for class String is declared: ~String() .

No, java does not support destructors . All freeing the memory task is done by GARBAGE COLLECTOR. Java has it’s own memory management feature using garbage collector. When you use finalize() the object becomes available for garbage collection and you don’t need to explicitly call for the destructor.

What is the destructor in Java? It is a special method that automatically gets called when an object is no longer used . When an object completes its life-cycle the garbage collector deletes that object and deallocates or releases the memory occupied by the object.
