Generally speaking, a for loop is used when you know how many iterations you need.

Otherwise a while loop is used and is terminated when a condition is met.

That's not to say that there isn't instances where you could use either. And both can be broken out of prior to the condition that would naturally end them.
Usually i use a while statement when i don't know form start when the loop will end.

If the numbers of cycle are known, i prefer a for loop.
for statements also allow you to keep code less cluttered as well.

for ( int i = 0 ; i < length ; i++ ) {}

it does all the counting up there so you dont have to have it in the block :D
