Demo for break, continue, label.

So java keywords break and continue have default value, it's the "Nearest Loop", Toady a few years after use Java, I just got it  !

Demo for break, continue, and label:

Java keywords break and continue have a default value. It's the "nearest loop", and today, after a few years of using Java, I just got it!

Demo for break, continue, label, so java keywords "break, continue" have default value,it's the "Nearest Loop"  ,Toady a few years after use Java  ,i just got it !

it's seem used rare,but useful
