TMA Instructions
This TMA assesses your work on Units 1-7 of M257. The marks allocated to
each part of a question are indicated in the margin. The total marks for each
question are shown at the beginning of each question.
For TMA questions that require coding, a number of marks may be awarded
for the style of your Java code. This means that we expect you to be
consistent and to follow good practice in the naming of identifiers and
layout.
In this TMA, you should do the following:
1- You should develop the required classes on NetBeans IDE.
2- You are required to create a Word file named

theoretical questions, and add snap-shots for the output as it is
specified under each part.
The TMA for the course has been uploaded to the LMS. You should start
working on it right away. Please note the following when working on the
TMA:
• No group work is allowed for the TMA. Each student must submit
his/her own solution individually.
• Copying the answers from any source other than your own work will
