Exits from the current method, and control flow returns to where the method was invoked.
Has two forms: one that returns a value, and one that doesn't. To return a value, simply put the value (or an expression that calculates the value) after the return keyword.
The data type of the returned value must match the type of the method's declared return value. When a method is declared void, use the form of return that doesn't return a value.
