COMP553 PRACTICAL EXERCISE 2 - TRIANGLE RECOGNITION

1. REQUIREMENTS

Produce a Java program which, given three sides of a triangle, determines whether the triangle is:

1. Equilateral - all sides the same length,
2. Isosceles - two sides the same length or
3. Scalene - no sides the same length

Assume that any individual side must be a positive number not greater than 100.0.

Note: You might find it useful to look at the notes on choice points and the Java "if-else" statement.

2. REPORT

You should hand in a report comprising the following sections:

1. Requirements: (outline of the above requirements)
2. Analysis and Design: A short description of your analysis of the problem including a Class Diagram outlining the class structure for your proposed solution. Detailed descriptions for the methods you intend to include. A Control Flow Diagram for you design.
3. Implementation: A computer print out of your implementation.
4. Testing: A set of appropriate test cases with the output from your program as a result of running these test cases.

Marks will be distributed evenly over: analysis and design; implementation; and testing. Refer to guidance notes on the presentation of work if necessary.

3. MARK SCHEME

Marks will be awarded for:

1. Analysis and Design (25%)
2. Implementation (50%)
3. Testing (25%)
