Program 1: Writing Your Own Class

Purpose

The purpose of this assignment is to write a custom class that integrates with an existing test program.

Partners

You may (and are encouraged to) work with at most one other partner on this assignment. You and your partner must be in the same lab section. If you work with a partner, submit one solution with both of your names on it.

Assignment

Create a BlueJ project named Program1 and place this TestProgram.java file in it. Your task is to add the missing GringottsAccount.java file to the project such that when the TestDriver is run, it produces exactly this output.

Grading (30 points possible)

• 18 points - the GringottsAccount class contains the appropriate 9 methods and these methods are correct (2 points each).
• 2 points - the GringottsAccount class contains the appropriate 4 instance variables.
• 2 points - the GringottsAccount class contains the appropriate 2 class constants.
• 1 point - the GringottsAccount class contains an appropriate javadoc class comment.
• 2 points - the GringottsAccount class contains appropriate javadoc comments for each method (including parameters and return types).
• 1 point - the GringottsAccount class contains appropriate comments for each instance variable and class constant.
• 4 points - when your program is run with TestProgram.java, it produces exactly the desired format of output.

Helpful Hints

• The Course.java file covered in lecture on Wednesday, September 17th shows a class that is appropriately commented.
• The TestProgram.java file above contains comments that should help you create the GringottsAccount class.

Submission

E-mail the GringottsAccount.java file as an attachment to your lab TA no later than the start of your lab on Tuesday, September 30th. Late submissions receive no credit, but partial credit can be earned by making an ontime submission. The subject of the e-mail should be CS 160, Program 1, your name, your partner's name.
