Debugging in JBuilder

1. create a directory jdbproject on your floppy disk (or as a subdirectory of a directory in which you want to work)
2. create a subdirectory pastri (pascal's triangle) for the project done in lab 8
3. create subdirectories src and classes of pastri
4. choose Start -> Class -> cs -> JBuilder3.5 -> JBuilder3.5
5. choose File -> New project
enter: A:\jdbproject\pastri\Pastri.jpr
6. choose Project -> Add to project -> Add file
enter: A:\jdbproject\pastri\src\Pastri.java
select "yes", when asked if the file should be created
7. double click on Pastri.java in the left part of the JBuilder window
8. cut and paste code from the lab into main part of window
9. select File -> Save All
10. copy ConsoleReader into A:\jdbproject\pastri\src\
11. select Run -> Run project
click "Set" button next to "Main class"
select Pastri
12. select Run -> Step over to start debugging
• use Help -> Help topics
• select Debugging Java programs
• scroll down until you see a table explaining the "Debugging Toolbar"
• find out how to "Reset Program", "Step over", "Step into", and "Add Watch"
• to inspect a variable, right click with the mouse and select Evaluate/Modify and enter the variable name
• to toggle a breakpoint click on the grey area left of your code
• to look at the variables set by "Add Watch" click the glasses left of the output window above the debugging toolbar at the bottom
13. At the end of the session select File -> Close Project and click to save unsaved files as desired.  This is necessary to ensure that other students won't be held up because JBuilder looks for a floppy disk and doesn't find one!!
