Variable declaration/memory use

Question

Do you use more memory if you do
int q = stringBuffer.indexOf("cat");
stringBuffer.insert(q, "your ");
than
stringBuffer.insert(stringBuffer.indexOf("cat"), "your ");
I would think no...

Answer 1

So you should
go with the second version!How do you come to that conclusion? This kind of
thinking just leads to to code cramming andultimately
hard to maintain code. AND all stack allocationsare
released when the method finishes.Title: "variable declaration/memory use"
That's why I came to this conclusion! Let's say that
in this method you have a for(;;) that never breaks
(like a daemon), this memory is never released, is
it?
Well, to be picky, the question was which uses more memory, not which is better.
In any case, the answer "A uses more memory than B" does not automatically imply "Therefore B is better." This kind of microoptimization is rarely useful. If you're so tight on stack that coding like that makes a difference between your program running or breaking, then you probably either need more memory, or, more likely, a better design.
