BodyPart.java

Creature.java

package javaapplication2;

import java.util.HashMap;

    public HashMap<String, BodyPart> bodyparts = new HashMap<String, BodyPart>();
    // The hashmap is for quickly retrieve bodypart that the user wants
    
    public Creature() {
    }
    
    public void addBodyPart(BodyPart bodyPart) {
        bodyparts.put(bodyPart.getBodyPartName(), bodyPart);
    }

        BodyPart bp = bodyparts.get(bodyPartName);
        int newHealth = bp.getHealth() - decrement;
        bp.setHealth(newHealth);
    }

CreatureBuilder.java

package javaapplication2;

    }
}

        c.hit("head", 25);
        
        System.out.println("------------------");
        listCreatureBodyParts(c);
