SQUARE AND CUBE A NUMBER USING EXCEPTION IN JAVA

In this article I would like to share with you a program that I wrote in Java that will ask the user to give a number and then our program will compute the square and cube of the given number I added exception handling routine to check for invalid entries.

I am currently accepting programming and web development work kindly contact me in the following email address for further details. Thank you.
