Question

I’m looking at some lwjgl’s tutorials and occurred to me instead of keeping the class instantiated in a variable, instantiate it and call the method directly without saving the object.

I was wondering if it’s good to do this when you don’t have to reuse the object later, or whether it is best to always keep the object.

I mean this:

(new Lesson02()).run(fullscreen);

instead it:

Lesson02 l2 = new Lesson02();
l2.run(fullscreen);

Thanks.

Answer 1

There is not really any difference if you do not plan to use the object later. So option 1 is fine. If you follow option 2 and end up not using l2 later in the code then it will get garbage collected anyway.
