I'm going through the first chapter of the OCA SE 8 book by Boyarsky and Selikoff. It suggests that I create 2 files in terminal and then compile and run the result.

ClassA.java:


ClassB.java:


The files are in /Users/me/tmp/packagea and /Users/me/tmp/packageb.
From the /Users/me/tmp directory I use
javac packagea/ClassA.java packageb/ClassB.java
to compile the code, and then
java packageb.ClassB
to run it.

All works well until I try to run the code, at which point I get:

Error: Could not find or load main class packageb.ClassB


Any ideas would be welcome. If I can't get through the first chapter I'm doomed!

Welcome to the Ranch

Have you copied the code and instructions exactly? It says packageab in one place and packageb in the other.

Campbell - thank you!

You have good eyes, while I, apparently, don't.


At least I know my system is working....

Everybody makes that sort of mistake every now and again, and . . .

It is sorta covered in the JavaRanch Style Guide.
