Hi, the problem below is primarily complete. I just need assistance with the portion highlighted in bold. I'm not sure how to code for a method that accepts a list of items and automatically maximizes the items based on weight (25 tons or less).

Below I have list the assignment instructions in italics, primary base code, Item class, Equipable subclass, Consumable subclass, and Weapon subclass.

ASSIGNMENT INSTRUCTIONS

While out on a standard run we stop in at our local fence and try to sell some of our items. When we board his ship we notice that we are the only people on board, so we instantly start grabbing things and loading them on our ship and get ready to run. While grabbing things we realize that we are going to run out of space extremely quickly and we should prioritize what we grab to maximize our financial gain while staying under our weight limit.

We dont have time to figure this out now as Gweedar might come back at any moment and catch us stealing from him which would result in our instant death.

Create an algorithm that maximizes the amount of money we will get if we ever come across this situation again. We will call this method ransack and it should accept a large list of items and return the optimal list of items we should grab based on our weight limit.

We must now store our items in a file and read from the file if prompted by the user. You can create a file with the list of items so you never have to type them in again, and you can control the items that are introduced to our world.

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

We now classify our items by separating them into 3 distinct categories Equipable, Consumable or Weapon. (You must implement these 3 classes that are subclasses of Item and they must have at least 3 unique attributes in each subclass)

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).
