CSSE 220 – Homework

Homework 1b

Objectives

Practice with primitive types, objects, and methods in Java.

Tasks

Programming: We started these in class. Please finish them and commit your answers to your SVN repository.

In Eclipse, checkout the ObjectsAndMethods project.
- Use the SVN Repositories view to check out this project.
Edit the file SomeTypes.java, completing each of the TODO items listed in the main() method.
Edit the file FourRectanglePrinter.java as follows:
1. Construct a Rectangle object using the four random values generated for you. Store the object in a new variable named box.
2. Print the location of the rectangle by calling System.out.println(box).
3. Translate and print the rectangle three times, so that, if the rectangles were drawn, they would form one large rectangle:
From BigJava, Exercise P2.3
Edit the file StringPractice.java, completing each of the TODO items in the file.
- The UML class diagram for String in the session 2 slides gives all the String methods that you will need.

Remember, in all your code:

Write appropriate comments:
- Javadoc comments for public fields and methods.
- Explanations of anything else that is not obvious.
Give self-documenting variable and method names:
- Use name completion in Eclipse, Ctrl-Space, to keep typing cost low and readability high.
Use Ctrl-Shift-F in Eclipse to format your code.
Take care of all auto-generated TODO’s.
- Then delete the TODO comment.
Correct ALL compiler warnings.
- Quick Fix is your friend! But make sure you know what it’s doing for you. Sometimes it’s fickle.

Here is the grading rubric for the ObjectsAndMethods project.
