separate methods and method invocations (calling a method) in the main method

Note that average is now a double variable.

Separate methods to perform arithmetic operations of sum, average, product, max and min of three integer numbers. Five (5) methods are needed.

In the main method, prompt and accept user inputs for three integer numbers, and invoke (call) the above methods to display results.

should be done in java.
