Background - your role
As a lead systems developer for iDev3, you have been assigned as a consultant to work with Wrigley Inc (the gum company).
Your project consists of developing a prototype applet for web-based inventory management.
To do this, you are going to develop a simple model of an object-oriented system. This model should be able to provide all the working examples of inheritance, encapsulation, and polymorphism through the use of a class, methods, and objects.
Your challenge - Building a comprehensive example
Begin by creating a simple class structure that contains:
- Proper User Interface objects
- Method(s) for the click of 2 buttons, a calculation that uses dollars and cents.
- Allows for user data input and conversion
Your interface might look something like this...

Considerations - What to include and how to improve your grade
- Remark EVERYTHING - use remarks in your code to tell me things like "This is encapsulation of a class", "This is creating the Parent class", "This is attached so the code listens for a click" - do this with everything in your code so I know that you know what the parts are and what they do. Also use remarks in your code to explain the "business process" of what needs to be done for the user to do his/her job and why.
- Create multiple methods - You should try to create multiple methods - one for each task.
