Hi sharpers
This is Mahesh again after some break. In this article I am going to show how to call java program using C#.  

According Microsoft definition of C#: -
揅# is a simple, Modern. Object Oriented language and combine the high productivity of VB and the raw power of C++?/font>

According Mahesh definition of C#: -
揅# is Simple, Modern, Object Oriented beautiful language and daughter (SHE-SHARP) of Java and Microsoft ?/font>

What I want to say SUN (sun) and MS (moon) both are very Important to IT WORLD (world) but both are now enemies now a days they are making languages to dominate each other.  This is sure without sun and moon there is no world like that with out SUN and MS there is no IT WORLD. I pry to god to make both are good friends they should work for IT PEOPLE.   

This application has 4 files

shesharp.cs
javasharp.java
comp.bat  //for compel
j.bat  
In this application I used Inner class for developing panel.

using System.Windows.Forms;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Diagnostics;
using System;
