There has to be only one Destructor in a class . A Destructor has no return type and no parameters. If we do specify a destructor in class then, the compiler creates a default destructor.
Read moreDo you need a destructor in Java?
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 .
Read moreWhat is destructor example?
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() .

Trivial destructor The destructor for class T is trivial if all of the following is true: The destructor is not user-provided (meaning, it is either implicitly declared, or explicitly defined as defaulted on its first declaration) The destructor is not virtual (that is, the base class destructor is not virtual)
Read moreWhy is there no destructor in Java?
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.
Read moreWhy do we need pure virtual destructor in C++?
It is must to provide a function body for pure virtual destructor as derived class’s destructor is called first before the base class destructor, so if we do not provide a function body, it will find out nothing to be called during object destruction and error will occur.

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.
