Error with inheritance when adding packages

[Zorrent12]

I'm learning java from the tutorial on oracle. As I'm going along, I'm adding what I learn to a game prototype I'm working on. I recently reached the packages section and added the following to each of my files:

package com.haliglond.demo;

After trying to recompile the files, I got several errors suggesting the class I tried to compile doesn't inherit the fields from its series of super classes. I'm sure the name in the package statements is consistent, as I copied and pasted it. Can someone explain what I did wrong?

Here's what the file I tried to compile looks like:

package com.haliglond.demo;
import java.util.Random;
import java.awt.Rectangle;
public class Orc extends NonPlayerCharacter {

     Random hitGenerator = new Random();

     public Orc(String selectedName) {
          name = selectedName;
          id = ++numberofCharacters;
          target = null;
          hitBox = new Rectangle(3, 3);
          attackable = true;
          dead = false;
...

Here's what the NonPlayerCharacter class looks like:

package com.haliglond.demo;
public class NonPlayerCharacter extends Character {
     
}

And here's what the Character class looks like:

package com.haliglond.demo;
import java.awt.Rectangle;
public abstract class Character {

     protected static long numberofCharacters = 0;

//Basic fields
     protected String name;
     protected long id;
     protected Character target;
     protected Rectangle hitBox;
     protected boolean attackable;
     protected boolean dead;
...

Maybe you haven't gotten to this page yet:

Actually, I believe I have. My files are in a series of folders that match the package name (com/haliglond/demo) and my classpath is set to that folder, but I'm still getting errors.

Would you mind posting the rest of your code, or an SSCCE, so I can try to reproduce your issue?

Alright, here's the code. I've cut out some of the methods and a couple fields that I'd like to keep private. However, I've tried compiling files that contain just this code and got the same error.

          target = null;
          hitBox = new Rectangle(3, 3);

EDIT: I just did some testing and found that it's confusing my Character class with a java.lang class. I changed it to GameCharacter, and got the following error when compiling NonPlayerCharacter.java:

NonPlayerCharacter.java:2: cannot find symbol
symbol: class GameCharacter
public class NonPlayerCharacter extends GameCharacter {


1 error

You gave me your Character class twice, and I don't see your Orc class. I also don't see GameCharacter anywhere, which is what your compile error talks about. And it says that's in NonPlayerCharacter.java -- do you have another copy of NonPlayerCharacter.java lying around somewhere? Or maybe there's a NonPlayerCharacter.class file somewhere that needs to be deleted.

Actually, that was just a mistake while posting. I've updated the post. Sorry. Also, I don't have another NonPlayerCharacter class around.

[gcalvin]

Well, now your Orc class just says package demo; rather than package com.haliglond.demo; -- is that how it is on your real code?

-Gary-

[Zorrent12]

At this point it is. I tried removing some of the earlier parts of the package name in my files to see if that would do anything. However, that didn't do much.
If you want, I can upload the files themselves onto a site for you to download.

[gcalvin]

Well, GameCharacter needs to be in a file called GameCharacter.java. With that fix, and with the fix of the package name in Orc.java, it compiles for me without complaint.

Thanks for your help. I'll fix that.
