The Problem

Suppose you are a software engineer working for a small software consulting company called J Software. A high school has contracted your company to computerize their tests. Your company would provide software for the client to create tests that students can take on computers. Your project lead has analyzed the requirements and came up with some Java interfaces for type of questions the program must support and has assigned to you to implement the solution. The implementation of the interfaces will also be used to created the two programs that will be used by the school. The first program is for creating questions for tests and the second program is for administering the tests to students.

The Interfaces

The interface code is posted on blackboard. Download them and add them to your NetBeans project. Below are the interfaces provided for you:

• Type of questions interfaces

o IMultipleChoiceQuestion

o ITrueFalseQuestion

o IFillInBlanksQuestion

o IShortAnswerQuestion

o IQuestion

• Question set and question factory interfaces

o IQuestionSet (a collection of questions)

o IQuestionFactory (a factory to creating questions)
