Compiling in Terminal on MacOS High Sierra

[Charles Cavin]

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:

package packagea;

public class ClassA {
}

ClassB.java:

package packageab;
import packagea.ClassA;

public class ClassB {
	public static void main(String[] args) {
		ClassA a;
		System.out.println("Got it");
	}
}

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....
