Intro to Java 10/17/20 Homework

For your homework today, write a program that calculates and prints out the average of three numbers. It should declare and initialize four double variables, one for each number and one for the average. Challenge: use a Scanner to read in the three numbers from the user. (You do not have to use any functions to solve this homework assignment.)
