My First Applet!!!

This is my first applet!

This is my first Java applet. Although it's a simple stack Calculator, it took me kinda long to write it. So, I hope you like it.

Directions: This is a Stack Calculator, which means that when you want to perform an operation on two numbers, you enter the two numbers first, then press the key for the operation.
Example: Adding 1 and 2.
Press '1' then 'Enter' then '2' then 'Enter' then '+'
