Inventory System

 

Due: February 11

 

Objective

To get experience working on Java programs combining multiple classes, constructors, methods, array lists, enumerations, and static methods.


 

Task

For this assignment, you will write a program which models the inventory system of a role playing game. In these types of games, players can carry around a set of items called their "inventory".

Each item has a descriptive name, a weight, a value and a strength. The value indicates how much the player could sell the item to a merchant for. The strength only applies to some items (like weapons and armor) and indicates how powerful the item is.

The weight comes into play because the player can only carry a fixed upper limit. If picking up a new item would cause the player to go over their weight limit, then they cannot pick it up (at least until they drop something else).

The system will let the player do the following things:


 

Classes and Methods

For this project, I'd suggest making the following set of classes and methods. Of course you can add other methods if you find them helpful.


 

Example Run

Below is an example run to give you an idea of how this can work. Your program doesn't have to work exactly the same way. Also, the items you generate will of course be different.
