about garbage collector when deleting a node from LinkedList

this is a sample code from delete function in my LinkedList class which deletes a node from middle.

        temp.getPrev().setNext(temp.getNext());
        temp.getNext().setPrev(temp.getPrev());
        temp.setNext(null);
        temp.setPrev(null);

my question is do i have to set temps next and prev references to null or does garbage collector handle with this automatically_?. i will appreciated very much if you can help me. and thanks anyway.

Solution

  • Garbage Collector analyze if there is any reference to an object. Since there is no reference to temp after your method is finished, GC should remove this object.
