I am in the process of putting together a simple RPG game engine in java. At this point everything works fine while all my classes are in one directory. Basically, I know I am going to end up with a heap of files and wish to organise them into a package structure. I followed the directions at http://www.jarticles.com/package/package_eng.html but can't seem to make the magic happen. The two classes posted are the least dependent of the lot and I figure if I can get these working then the rest shouldn't be a drama. For the record I am using openJDK in Leeenux (remix of Ubuntu netbook Remix)
First class
package adventure.engine;
import java.util.*;
public class Inventory
{
ArrayList itemList = new ArrayList();
public Inventory()
{
}
public void addItem()
{
}
public void removeItem()
{
}
}
And the second:
package adventure.engine;
import adventure.engine.*;
public class PlayerCharacter
{
private String name = "Player";
private String race;
private String plrClass;
private int level;
private int xp;
private int levelXp;
private Inventory inventory = new Inventory();
//---------
//Abilities
//---------
private static final String[] abilitiesList = {"Strength",
"Dexterity",
"Constitution",
"Intelligence",
"Wisdom",
"Charisma"};
private int[] abilitiesValues = new int[abilitiesList.length];
//------
//Skills
//------
private static final String[] skillsList = {"Acrobatics" , "Insight",
"Arcana" , "Intimidate",
"Athletics" , "Nature",
"Bluff" , "Perception",
"Diplomacy" , "Religion",
"Dungeoneering" , "Stealth",
"Endurance" , "Streetwise",
"Heal" , "Thievery",
"History"};
private int[] skillsValues = new int[skillsList.length];
//***********

public int getLevelXP()

}
} //public class PlayerCharacter
Classes reside in /home/user/Java/adventure/engine
Output from echo $classpath is /home/james/Java:/.:
when I attempt to compile the second class I get the following error:
PlayerCharacter.java:18: cannot find symbol
symbol : class Inventory
location: class adventure.engine.PlayerCharacter
private Inventory inventory = new Inventory();
^
PlayerCharacter.java:18: cannot find symbol
symbol : class Inventory
location: class adventure.engine.PlayerCharacter
private Inventory inventory = new Inventory();
Any feedback on this would be greatly appreciated.How to solve this?
