You create a variable to store a value that you can refer to that variable in the future. I've heard that you must set a variable to 'null' once you're done using it so the garbage collector can get to it (if it's a field var).
If I were to have a variable that I won't be referring to agaon, would removing the reference/value vars I'm using (and just using the numbers when needed) save memory? For example:
int number = 5;
public void method() {
System.out.println(number);
}
Would that take more space than just plugging '5' into the println method?
I have a few integers that I don't refer to in my code ever again (game loop), but I've seen others use reference vars on things that really didn't need them. Been looking into memory management, so please let me know, along with any other advice you have to offer about managing memory
