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
M257_TMA_Spring16_ID_Name. Then you are required to do the following:
• Copy and paste the codes of each part and the answers of the
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
be considered as plagiarism.
• Use your own words to answer essay questions.
• Read carefully the second page of the TMA for important
instructions.
After you finish solving the TMA, You have 2 submission links:
1- The Regular Submission Link: you need to submit to the regular
submission link a compressed file (e.g. zip file) which includes the
following: your NetBeans project folder (in Windows 7, you can find
this under Documents/NetBeansProjects),
2- The Turnitin submission Link: You need to submit a document
Word file including your answers to all questions according to the
guidelines on the cover page of the TMA.
Your TMA will not be marked if all the required files are not submitted on the
2 submissions’ links.

Part 1.2 [10 marks]
Develop a public class MyDate to the following specifications:
• The class 3 private integer instance variables day, month, year
• The class has a multi-argument constructor that sets the value of its
instance variables to given values.
• The class has a zero-argument constructor that sets the value of its
instance variables to their default values. It should invoke its multi -
argument constructor in the same class.
• The class has the setter method setMyDate for its instance variables.
• The class has the getter method getMyDate for its instance variables in
order to return a string representation of the MyDate instance variables.
Part 1.3 [15 marks]

• The class has 2 private string instance variables flightNo, bookingRef.
• The class has 1 private instance variable of the class MyDate.
• The class has a multi-argument constructor that sets the value of its
instance variables to given values. It should create the object of MyDate
and set the values of day, month, and year using appropriate method.
• The class has a zero-argument constructor that sets the value of its
instance variables to their default values. It should invoke its multi -
argument constructor in the same class.

Part 1.5 [20 marks]
Develop a public class Journey to the following specifications:
• The class has a private instance variable HashMap , which
represents a collection of Tickets of class Ticket.

of objects that will be added to the collection. You need to decide the correct
place to be able to increment it once an instance object is added into the
collection.

HashMap , instance object.
• The class has a public method void addTicket (Object) which adds an
instance object of ticket of TicketID class into the collection.
• The class has the method displayAll (). It returns either a string
representation of the HashMap collection with all its different types of tickets
or a string message that “NO tickets are available”.
• The class has a method void saveIntoFile(String). It saves the contents
of the HashMap collection of tickets into a file. The file name is the argument
