Trying to create a package for my java application - linux

Question

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 PlayerCharacter()
{
level = 1;
xp = 0;
levelXp = 1000;
setAbility("Strength", 8);
setAbility("Dexterity", 10);
setAbility("Constitution", 10);
setAbility("Intelligence", 10);

setAbility("Charisma", 10);
} //public PlayerSheet()

break;
}
}
return val;
}
//retrieve an ability value by index number

}
}
return val;
}
public int getSkill(int i)
{
return skillsValues[i];
}
public String getName()
{
return name;
}
public String getRace()
{
return race;
}
public String getPlrClass()
{
return plrClass;
}
public int getLevel()
{
return level;
}
public int getXP()
{
return xp;
}
public int getLevelXP()
{
return levelXp;
}
} //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?

Answer 1

Two things.
1) You might not have compiled Inventory
2) PlayerCharacter and Inventory are in same package. So there is no need to import.
You should be compiling them as
javac adventure/engine/Inventory.java
javac adventure/engine/PlayerCharacter.java
