The "prevalent awareness" of programming is that x += y is an equal shorthand notation of x = x + y. As long as x and y are of exactly the same type (for example, each are ints), you might look at the two statements equivalent.

A different stage worthy of thing to consider is numbers within the variety of 'byte' knowledge form are cached in java and thus numbers -128 to 127 are of sort byte in java and so this code doesn't have any compile glitches:
I also use this class to save consumer Choices, Home windows and whatnot to get reloaded at runtime. It's very user friendly and productive.
