Hi Han

While is used to create a loop based on the outcome of a calculation. For example in english you could say while the car is dirty keep washing, the same is true in programming, while a condition is true the block of code will continue to literate over and over again until the condition is met and the code can break out of the loop.

There are numerous loop types in java and some suit situations better than others, while loops can be dangerous as if the condition is never met you can end in an unintentional infinite loop but are great if you handle the condition correctly

Hope this helps Daniel
