I noticed something regarding the java command that I wanted to ask about. I created a temp folder on the root of C:\ then I created two more folders called packagea and packageb. In those folders were java files called ClassA and ClassB respectively. I compiled them by running javac packagea/ClassA.java packageb/ClassB.java
So then I tested to make sure it worked by running java packageb.Classb - which is where I coded the main method - and it worked. OK, good so far.
I changed my working directory to C:\temp\packageb and then attempted to run java ClassB and that does not work. I get:
Error: Could not find or load main class ClassB
Could anyone explain what is happening here?

So you need to launch the program from a folder that can see both packageA and pacakgeB, or you need to have a classpath entry to each folder.
