Sum and Average of Five Numbers Using Two Dimensional Array in Java

Two dimensional array is also known as matrix in Java in this article I would like to share with you a sample program that I wrote that demonstrate how to declare and use two dimensional array in Java programming language I called this program Sum and Average of Five Numbers Using Two Dimensional Array in Java.

What does the program will do is to ask the user to enter five numbers and then the program will compute the sum and average of the five numbers given by the user.

If you have some questions about programming, about my work please send mu an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com. People here in the Philippines can contact me at  my mobile number 09173084360.

Thank you very much and Happy Programming.

Problem No. 1:

  

Write a program that will ask the user to give five numbers 

and then our program will find the total sum and average of

five numbers using two dimensional array.
