Assignment 1

Due Date : 1/30 @ 11:59pm

Instructions

Each of you should have a repository in CCIS's GitHub with the name assignment1-ccisLogin. Use this repository and add all your work there. In order to clone the repositories from CCIS GitHub to your machine (or watch this video video instructions):

1. Sign in to GitHub.

2. On your CCIS GitHub home page your Github Handle should appear on the left as a button/drop down menu. Click that button and from the drop down menu select cs8674sp15-seattle. The CCIS GitHub page will then navigate to the class' web page and to the contents that is available to you.

3. On the right you should be able to see all repositories to which you have been given access. Find the repository whose name matches the pattern assignment1-ccisLogin, where ccisLogin is your CCIS login name, e.g,assignment1-john123, and click on it.

4. On the repositories home page look at the bottom right hand corner for a button with the text Clone in Desktop. By clicking on this button your browser will launch the GitHub client that we installed in Lab1 and ask for a location on your drive to store the repository.

   If you are not using the GitHub client the clone URL is located above the Clone in Desktop button. Copy the URL and issue the following command on your shell git clone URL.

5. Create a file and save it under the folder on your drive that you selected in the preceding step.

Remember to push your changes to the CCIS GitHub repository often.

Assignment Rules

1. You are not allowed to use any JDK APIs other than java.lang.
2. For any Java class that contains methods you are expected to provide tests using JUnit.
3. For any Java class you are expected to provide valid Javadoc documentation. This means that running Javadoc on your your source code should successfully compile and generate documentation in HTML.
4. For any images, e.g., for Class Diagrams, you are expected to provide a PDF version of the image.

Problem 1

All Java source code that is part of your solution to this problem must reside inside a java package with the name edu.neu.ccs.cs8674.sp15.seattle.assignment1.problem1

A friend is trying to create a program to keep track of their library of books. He has started designing the program and after a first iteration your friend has create the following UML class diagram.

Your friend asked you to create the code based on his Class Diagram. Also your friend has asked to implement the following

• Book
  1. implement the toString() method for Book and provided the following as an example: for the book "The Unbearable Lightness of Being", written by Milan Kundera published in 1984 with ISBN 9780061148521, it should output "The Unbearable Lightness of Being", Milan Kundera (1984), ISBN:978-0061148521
  2. implement the equals() and hashCode() methods such that two Books are considered the same if and only if they have the same title, author, year and ISBN. Ensure that your implementation satisfies the contracts for both methods equals(Object): boolean and hashCode(): int
• Author
  1. implement the toString() method for Author so that it returns in order the first, middle and second name separated by spaces. In the case that an author does not have a middle name return a string composed of the first and second name separated by one space.
  2. implement the equals() and hashCode() methods such that two Authors are considered the same if and only if they have the same first, middle and second names. Ensure that your implementation satisfies the contracts for both methods equals(Object): boolean and hashCode(): int
• Isbn
  1. implement the toString() method for Isbn so that it returns in order the prefix followed by a hyphen, followed by group, publicationElement, registrationElement and checkDigit.
  2. implement the equals() and hashCode() methods such that two Isbns are considered the same if and only if they have the same prefix, group, publicationElement, registrationElement, and checkDigit. Ensure that your implementation satisfies the contracts for both methods equals(Object): boolean and hashCode(): int
• Year
  1. implement the toString() method for Year so that it returns a string representation of the value val inside Year.
  2. implement the equals() and hashCode() methods such that two Years are considered the same if and only if they have the same Integer value. Ensure that your implementation satisfies the contracts for both methods equals(Object): boolean and hashCode(): int
• Title
  1. implement the toString() method for Title so that it returns a string representation of the value val inside Title.
  2. implement the equals() and hashCode() methods such that two Titles are considered the same if and only if they have the same Integer value. Ensure that your implementation satisfies the contracts for both methods equals(Object): boolean and hashCode(): int

Problem 2

All Java source code that is part of your solution to this problem must reside inside a java package with the name edu.neu.ccs.cs8674.sp15.seattle.assignment1.problem2

You have been tasked to create the program to print boarding passes at airports. The boarding pass contains the following information

• The passenger's name. A boarding pass has one and only one passenger. The passenger has a first and last name and some might also have a middle name.
• The name of your destination. This is typically the name of a city.
• The name of your departure. This is typically the name of the city.
• The time of departure. Time is hours and minutes only. The hours are in 24 hour format; 0 to 23 where 0 is midnight and 23 is 11pm. Time should be displayed with hours first, then a colon : and then minutes
• The date of departure. This is the day, month and year, e.g., 01/22/2015. The example is also the way that the date appears on the boarding pass
• The gate from which you are departing. Gates have a composite name made up of a capital letter and a number, e.g., A87
• The passenger's boarding group. The boarding group is typically a number, e.g., 4.
• The airline with which the passenger is travelling, e.g., British Airways
• The flight number. The flight number is also a composed from two pieces of information, the airlines acronym and a number, e.g., BA8787

1. Provide a UML Class Diagram of all classes that are part of your design. (For diagramming tools see UML Resources)
2. Provide Java code for your design. For each class that you create ensure that you have appropriate implementation of toString(), equals() and hashCode()
