To clarify, this is specifically for Java.

Write a program that asks the user to enter the length of sides for one or more squares. The user indicates the end of the input by entering a negative sentinel value that is not use in finding the average values. The average should be a value of type double so that it is computed with fractional part.

Input: (Your input must match the following below):

Given a list of squares, provide a list of their sides in inches. Use a negative number to indicate the end of the list. I will then tell you the average square area (in inches^2) of all the squares 3 4 -1 

Output: (Your output must match the following below): (Average data type should be double)

Average square area of all squares: 12.5in^2
