1. Write a program using BlueJ to compute the average of three numbers, we will assume these numbers are test scores, so the range the numbers can be are 0-100.

2. The three numbers you will use will be user input.

3. The average is calculated by adding the three numbers and dividing the sum by three.

4. Your output should look similar to this: Your test score average is: xx

//with xx being the calculated average of the numbers
