B.A.M.F Challenge:
B.A.M.F Challenges & why you want to always at leas try them explained Here:
Difficulty: 1/3
Create a console program with a method that finds the average of a unknown amount of numbers(aka accepts a variable length argument in its parameters)Then test it in you're main method.

(Before starting any of the challenges always declare a class and a main method unless told otherwise)
1.Create a method that will return a int and name it "average".It should accept a variable length argument, name the variable length argument "numbers"

Inside the "average" method:

2.Declare a int variable, name it total and set it to 0.

3.Create a enhanced for loop that loops through the "numbers" parameter being passed in.

Inside the enhanced for loop:
4.set total+=x;

5.return total divided by the amount of numbers you passed in(hint: numbers.length)

Back in the main method:

6.Create a print line statement that calls the "average" method and place 8 values in its parameters.
