Question

Part1) Simple Calculator Programusing Scanners
Write a Java application that inputsthree integers from the user and displays the sum, average,product, smallest, and largest of the numbers. Use a Scanner objectto get the input from the user. Use System.out to output theresults. The average should be a floating point result, and shouldbe displayed with 2 digits after the decimal point.

Part2) Simple Calculator Program usingJOptionPanes
Student will modify the Java application fromprogram 1. The new version of the program will use JOptionPanes forinput and output. Use String.format("%.2f", doubleVariable) tocreate a string representation with 2 digits following the decimalpoint.

This is what I have for part 1 so far:
I haven started on part2 yet. Can someone please help me getthis program going? In part1 the sum, product and averagevalues has been executed but I can't seen to figure out the codesto get the smallest and largest value. And also I need helpto determine how to write a program for the second part(part2). Thanks
