Assignment Task specification

CQPC has decided to increase the charges for General pest control, Termite Inspection and Termite control fill jobs by charging additional charges depending on the number of rooms and halls in the customer's premises. The following table provides the details relating to the additional charges:

In order to include these additional charges in the Java GUIapplication, you may needto do any or all of the following:
- develop additional Java classes
- extend the existing Java classes that you have developed for your assignment1
- implement newly created interface(s)

CQPCalso wants to view the income generated by different contractors. Hence, you need to store the details of all the contract works performed in a file and also to provide appropriate searchingfacilities to display the details of contract work(s)that have beenperformed by the selected (searched) contractor. You can assume that CQPC gives contract works only to three or four pre-listed contractors whose details are already available (names of the contractors are left to your choice).

Hence the software application that you will develop in assignment should perform the following:

1. When the application is started,it should read all the completed contract works' details from the existing text file ("pest.txt") and display the latest-completed-contract work.

2. The application should provide necessary controls to search and display the details of contract worksperformedby a given/selected contractor (details to be obtained/selected from/by the user). If the search criterion is not met then an appropriate message has to be displayed.

3. The application should provide appropriate controls on the screen to obtain the data for a new contract work; perform error checking and display the details of new contract work. You are allowed to copy the relevant codes from your assignment 1 and use them for this purpose.

4. The application should have the facility to append/save the details of newly performed contract work in the same text file ("pest.text").

You are allowed to have additional controls that are required and to develop yourown layout for the assignment.

For your help in developing the Java application, a java file will be available later (around week 7) in your course web-page. It is not mandatory but the source codes from that java file can be used by you as part of your assignment 2 development.

Please note that you may need to add/delete/modifythe existing codes, methods, etc. in that java file so that your application performs appropriately including meaningful error/exit messages required if any.

Please note that you also need a text file "pest.txt" with appropriate contents for running the GUI application initially.

This is my assignment which is a programming one.

I have attached the assignment file, additional information file and another application called java application 8 zip (this is the first part of the assignment which i have done earlier and the second part you have to add to this programme( simply is a continuation of the first part.

Please note that i need you to follow the exact instructions and requirement that they ask in the assignment.

Make sure you use Netbeans platform to create this programme, it is a requirement
