Initialising

[thatos]

I have some variables which I just need for a certain loop, so I would like to ask is it better to initialise them inside a loop or before you enter a loop. I would like my algorithm to run faster.

Initializing them inside the loop means the initialization is done as many times as the loop is run.

Initializing them inside the loop means the initialization is done as many times as the loop is run.

So it will be better to initialize them outside a loop?

[r035198x]

How about some more info?
What kind of loop are you using? for, while e.t.c
Are the initial values of the variables known before the loop is run?

Also javap, the disassembler can give valuable information about the generated
code; it is part of Sun's jdk.
