I wrote this program to ask the user to give a number and then our program will check if the give number is a prime number or not a prime number using Java as our programming language.
I am currently accepting programming and web development work kindly contact me in the following email address for further details. Thank you.
My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
