ription Three Numbers (Required Exercise) In this exercise we'll be using a slightly different combination of things we've worked on before, starting from scratch again. No individual element here is new, so read the instructions carefully and break the task down into steps. In the skeleton you are given a class ThreeNumbers which starts with an array called num, and little else. Below the indicated comment you need to do the following (you may want to think about the order): • Create a standard main method. In the main method you need to: o Create a scanner object to be used to read things in o Print a prompt to "Enter the first number: ", without a new line after it. Read an int in from the user and store it as the first element of num. o Print a prompt to "Enter the second number: ", without a new line after it. Read an int in from the user and store it as the second element of num. • Print a prompt to "Enter the third number: ", without a new line after it. o Read an int in from the user and store it as the third element of num. Print "The sum of the three numbers is <sum>.", with a new line after it, where <sum> is replaced by the actual sum of the elements of num. o Print "The average of the three numbers is <avg>.", with a new line after it, where <avg> is replaced by the actual average (rounded down, so you can use integer division) of the the elements of num. Remember that computers aren't clever, so note the formatting and punctuation, especially in the feedback of the tests. Note also that part of the task is to use the array num. Although you can print out the correct things without it, you cannot pass the task.
