Is there a destructor for Java?

Question

Is there a destructor for Java? I don\'t seem to be able to find any documentation on this. If there isn\'t, how can I achieve the same effect?

To make my question m

Answer 1

No Java doesn't have any destructors .The main reason behind it in Java is the Garbage Collectors that passively works in the background always and all the objects are made in the heap memory , that is the place where GC works .In c++ there we have to explicitly call the delete function since there is no Garbage collector like thing.

Answer 2

If it's just memory you are worried about, don't. Just trust the GC it does a decent job. I actually saw something about it being so efficient that it could be better for performance to create heaps of tiny objects than to utilize large arrays in some instances.

Answer 3

There is no exactly destructor class in Java, class destroyed in java automatically by garbage collector . but you could do that using below one but it's not exact same thing :

finalize()

There was a question that spawned in-depth discussion of finalize , so that you should get more depth if required...

Answer 4

In Java, the garbage collector automatically deletes the unused objects to free up the memory. So it’s sensible Java has no destructors available.
