A simple Calculator.

This is a fun little program I made to help my brother with his homework.

The Homework Assignment
Find ten words that add up to 100 when a = 1, b = 2, c = 3, etc...

The Java Assignment
Take a text file that is a list of words in the english language (sorry I can't remember where I found it, but look for something that would help with scrabble), and write a program that checks each word and outputs it if it adds up to 100.

This is a webpage, aimed to teach beginner programmers to program using either C# or Java, Note it is not a TUTORIAL, those are mathematical exercises and expressions. Dependent on how good is your code's performance you get a score(stars up to 3). I find it very entertaining, hope you do too

We set up a program to output correct/incorrect leap year no matter what year entered and set up a program to output the chinese zodiac symbol based on the year you enter. Those were interesting starter Java programs.

I gave some suggestions for java bus ticket reservation system.

Heres a good one that I made..
Java IDE that compile the Java program and show the output

Features :

1. Compile (Only Java Program
2. Interpret / Run (Java Program)
3. Decompile (class files)

I've created this project in java and the project is platform independent
