Hey All,

Today's my first day learning Java. I've started taking an old Stanford Engineering Everywhere course (Standford SSE CS106A/172). I attempted to install the version of Eclipse found in their course documents (Release 3.2.1) but I was unable to install it. Instead I downloaded the most recent version straight from Eclipse.org. Then I downloaded their "Starter Code" found in Assignments.

I imported "Assignment 1" and now when I try to run the code I get an error:

Exception in thread "main" java.lang.NullPointerException
at acm.program.Program.main(Program.java:917)
at stanford.karel.Karel.main(Karel.java:202)



I'm wondering if there could be compatibility issues with the code provided by the course and the version of Eclipse I'm using, and that this could be my problem? Or, is there a simple configuration setting I need to set?

Any help would be much appreciated!

-Phil

Not having the source in question, I'd suggest you set a Java Exception Breakpoint (https://www.vogella.com/tutorials/EclipseDebugging/article.html#exception-breakpoints) for NullPointerExceptions and figure out which part of the statement on line 917 is null when it's not expected to be.
