Is it possible to make equipment of items(weapon/armor) through Hasmap(key is part of body and value is armor or weapon if it is hand)

MonkeyDjack :

I have a task to make a project in java with the usage of ArrayList, hashmap, abstract classes, and interface. I decided to develop a text-based RPG in java. I want to use abstract classes for monsters, ArrayList for inventory and hashmap for equipping armors and weapons, however, I don't really figure out if it is possible to make equip function with hashmap. I was thinking to make something like this

public HashMap<PartOfBody , Weapon/Armor> equipment;

I would love to hear from you about any ideas about how to do it.

You could implement something along the lines of this:

public Abstract class Equipment {}

public class Weapon extends Equipment {}

public class Armor extends Equipment {}

public class BodyPart {
    String part;
    public BodyPart(String part) {
        this.part = part;
    }
}

public class RPG {
  public static void main(String args[]) {
      HashMap<BodyPart, Equipment> equipment = new HashMap<BodyPart, Equipment>();
      equipment.put(new BodyPart("Arm"), new Weapon());
      equipment.put(new BodyPart("Head"), new Armor());
      equipment.put(new BodyPart("Arm"), new Armor());
  }
}
