The choice between for or while is pretty much a matter of readability and personal preference. I personally tend to use for loops only for dealing with situations where a numerical index is important (arrays and sometimes lists). For iterators, I tend to use while() loops, because it looks more natural to me.

I don't think there's any difference in performance pers? but you always need to be aware of when and how many times your condition gets evaluated.

Performance is VERY unlikely to be an issue.My only suggestion is don't have too many nested loops.

Even though it is a personal choice, I would have made the decision based on the following:

I would have used 'for' loop if i know exactly how much times i need to loop, say i need loop 30 times.

But if i don't know when a condition would be met, I would prefer to use a 'while' loop.

Before making the .class file of your .java file, the java compiler does a code optimization. In this step, all the loops are treated in a similar manner. It uses jumps to implement them.So, performance is not at all an issue.
