CIS 260 Computer Programming I

Getting Started with BlueJ

Make sure BlueJ is properly installed and has been configured to find the correct JDK.

Working in BlueJ: modify class GradeBook following the directions in Exercise 3.11 on page 125

Instead of writing a 'Test' class, use the BlueJ Object Bench to thoroughly test your modified GradeBook:

• Call all of the methods
• Inspect the Instance Variables
• Try 'stepping' through your methods using the debugger.

Hand In:

1. A printout of GradeBook (from BlueJ of course) with line numbers if possible
2. A Screen Print showing that the displayMessage method works correctly.
3. A two to three paragraph write up comparing BlueJ to the 'old school' notepad + command line procedure we used for the first couple weeks.
