# Arithmetic, Smallest And Largest Program In Java

The program below is the answer to Deitel's Java How to Program (9th Edition) Chapter 2 Exercise 2.17.

Question: Write an application that inputs three integers from the user and displays the sum, average, product, smallest and largest of the numbers. Use the techniques shown in Fig. 2.15. [Note: The calculation of the average in this exercise should result in an integer representation of the average. So, if the sum of the values is 7, the average should be 2, not 2.3333….]

if (num3 < smallest)

1. Thanks for the answers, but you forgot to set int largest; in your answer

1. Thanks for pointing that out. I've corrected it.
