While true is true. While just looks for a true/false value. Saying while(true) just skips the evaluation and will always loop, until you use a break. It's just a way to generate an infinite loop.

All a while statement does is look to see if a value is true or false. So if you put while(true), you can assume true is always going to equal true, and your loop won't stop unless you stop it.
