Multiplication Table in Java

In this short article I would like to share with you a program that I wrote using Java as my programming language I called this program multiplication table. What the program does is that it will display a multiplication table on the screen very similar that is being used in elementary mathematics.  

I hope you will find my work useful in learning how to program in Java. If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.

Thank you very much and Happy Programming.

Reverse a Number in Java Version 2

A simple program that will ask the user to enter a number and then it will reverse the arrangement of number given by the user.The code is very simple but it uses already the concepts of object oriented programming.

I hope you will find my work  useful in a sense the logic of programming is also applied in this simple program.

Addition of Three Numbers in Turbo Pascal

In this article I would like to share with you the first programming language that I have learned in college where I understand what is programming is all about. I'm using Pascal in my simple program Addition of Three Numbers using Turbo Pascal.  Pascal is one of the most programmer friendly programming language it a sense it uses common English statement and it is not case sensitive compared with C,C++ and Java.

However in today's standard Pascal is no longer being used in development primary reason majority of our software that is being developed is written in C,C++,C# or Java and other programming languages that has similar to C or C++.

What does our program will do is to ask the user to enter three numbers and then our program will compute and find the some of the three numbers given by our user.

I hope you will find my work  useful in a sense the logic of programming is also applied in this simple program.

If you have some questions please send me an email at jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
