Objectives

- Develop a Java GUI application using layout managers
- Develop an application that uses two or more classes
- Read and/or write from/to text files
- Use search algorithms and/or sort algorithms
- Use ArrayList or LinkedList or any other data structure

General

In your assignment 2, you can continue to developtheJava GUI application that you have created in your assignment 1. If you would like to modify the codes that you have submitted in your assignment 1, you are free to do so. You can adopt any layout pattern as suitable to the requirements of the application in your assignment 2.

Assignment Task specification

CQC has decided to increase the charges for Stencil work to $30/ square meter of surface area. They have also decided to undertake concrete cylindrical foundation work too. For a cylindrical column foundation, the diameter and depth measurement are required for calculating the volume of the concrete required. In order to include these additional changes 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 assignment 1
- implement newly created interface(s)
- implement generic methods and or generic classes

CQC also wants to view the income generated by different employees. Hence, you need to store the details of all the concrete works performed in a file and also to provide appropriate searchingfacilities to display the details of concrete work(s)that have beenperformed by the selected (searched) employee.

Hence the software application that you will develop in assignment 2 should perform the following:

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

2. The application should provide necessary controls to search and display the details of concrete worksperformedby a given/selectedemployee (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 to obtain the data for a new concrete work; perform error checking and display the details of new concrete 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 concrete work in the same text file ("concrete.txt").

You need additional controls that are required and to develop your own layout for the assignment 2. Please note that you can create the above mentioned text file through your application program for storing the concrete work data and then that file can be used by your application to read its contents during its subsequent run.

Note: If you need to make suitable assumptions for the development of the above Java application, please provide them in the form of comments in the test driver file.
