Destructor in C++,.Net but not in Java

Destructors

A destructor is a special method typically used to perform cleanup after an object is no longer needed by the program. C++ supports destructs, but JAVA does not support destructors.

It make destroy of objects to make memory free to get feature use of memory of ram .

There memory of heap and stack both will make free because objects get memory if heap and stack full then there will be an error. After destructor called…

1:- first of all stack memory will full because of thread store directly in to stack and object also but thread can store only in stack not store in heap

Exception will generate if memory will full

Stack out of memory exception will generate.

First of all stack will full then heap will not make continue to assignee or running application if stack overflow then heap will not work.

If stack give exception then heap will not work

Heap is depended on stack;

Syntax:-

Class Name()

Garbage Collection

The garbage collector is a part of the runtime system that runs in a low-priority thread reclaiming memory that is no longer needed by objects used by the program. An object becomes eligible for garbage collection in JAVA when there are no longer any reference variables that reference the object.

Syntax:-

System.gc();
