While out on a standard run we come across a strange planet that has a ship emitting an SOS beacon. We decide to proceed, not to help any survivors but to search for items. After our descent we find a crashed ship with a full cargo hold! We decide to take the time to empty their cargo hold and search through all of the items to determine what to take. We notice that they dont store their items in the same boxes that we do, but rather have a system that creates specific size boxes for each item. This means that they can store 200 items if they are light enough, or 1 large heavy item (Remember, weight matters when trying to leave a planet!).

While you continue doing the grunt work of unloading the ship I head back to our ship to try and update it with the same features as the newly discovered, but wrecked, ship. I get started as you finish unloading and reloading everything, so I head out to search for survivors while you finish the upgrades.

Items now have attributes such as Name, Weight, Value, Durability and ID. (Create an object called Item)

We can carry an unlimited number of items, as long as they dont exceed the maximum weight of the cargo bay, 25 Tons. (Use an ArrayList that checks an items weight before placing it in the cargo hold)

We need to be able to add and remove items by their name.

We need to be able to search for a specific type of item in our cargo bay based on the items name and one of its attributes (Implement 2 searches one on name and another on any attribute you choose).

We need to be able to sort items by their names alphabetically in descending order (A-Z)

We need to know how many of each item we have in our cargo bay and display their attributes.

We must also add a partial search (think of this as a filter option).

Using the same code as assignment 2 you can make your changes. I have included some base code for your convenience (This is 2 classes, Assignment2 and Item.
