Calculator in Java



Use JBuilder9 GUI facilities to develop a dialogue based application: a four function calculator plus backspace, and clear buttons to perform simple arithmetic. Use edit box(es), buttons, static text and other controls and any controls that you think necessary. **Also add your group member's student ID’s in the window bar of your calculator.


**w03134132, w03163958, w0308186 ( THESE ARE THE ID NUMBERS)**

Your calculator must be able to add, subtract, multiply and divide any given number. Any additional functionality will be a bonus.

**Mark Allocation:**

Program & Object Design 10

Algorithm Design Documentation (for each calculator function) 10

Functionality 40

Robustness 20

User Interface 10

Overall Presentation of work including user guide 10

**Marking Criteria**

**Program & Object Design**

*The appropriate use of Classes, Objects, Constructors, Methods, Variables, Constants and* *your overall structure will be looked at.*

**Algorithm Design Documentation (for each calculator function)**

*Every key used in your calculator must have certain functionality.


*In this* *documentation the algorithm (pseudocode) used to implement each function should be* *provided together with details of which group member implemented the function. This part* *of the assignment is an individual mark according to group member contribution.*


*Your calculator should run properly and conform to the specification.*


*How complete are the checks to ensure that only valid data are accepted.*


*A user friendly, attractive and colourful interface would be and advantage*


*Overall presentation of the completed work, including how well your files are organised*

*on the disk and the quality of the user guide produced.*

**What you need to hand in**

• A virus check dist containing your program which is written in JBuilder9 (*I will not accept* *any other compilers or any other versions preceding JBuilder9)


## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables):

a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.

b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.

3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
