Hello,
I would like to know how to explicitly destroy objects in Java.
In university projects I found that we override the function selfDestroy:
@Override
public void selfDestroy() {
current = null;
}
However, I can't find this anywhere on the internet.
P.S.: I know that Java is a language with GC.

There's autocloseable interface you could implement
This is done by IO stuff to close the underlying resources
But as long as it's standard java objects, you can just ignore it, the gc will take care of it
wide olive
Yeah but that's IO, in this case we're trying to implement a composition as described in UML

You can set any property to null, as long as it's not final
But I might be misunderstanding the question. Do you have a practical example?

It's as concret as this :p

Yeah, but in which function do I inject this line ? Like, is there a function that gets called before the destruction of an object, where I can remove the references (and potentially do other stuff) ?
The teacher's answer is to put, in this case, B as a inner class for A
rose lynx
No, those were finalizers and those are deprecated
In Java you don't have to remove references
Just don't reference the object anymore
The garbage collector will take care of the rest
