Create a class Purchase with the following fields,

• Item code

• Item type (can be one of cosmetics, electronics, and medicine)

• Price

• Quantity

• Type of purchase (Credit or debit)

Include necessary methods to initialize objects, getter and setter methods, and toString().

Construct a collection of such Purchase objects. Then answer the following:

(a) Display the item code whose price is greater than X (you can assume your own price) and is purchased in debit

(b) Partition the list of purchases into Credit and Debit and display the credit purchases only

(c) Group the purchases based on the item type in the sorted order of their price and then quantity

What I have tried:

You can start your task with the followin steps:
1. Create a Class with name Purchase and then create the properties in Purchase class
2. Item code, Itemtype (Create Enumeration), Price, Quantity, TypeOfPurchase
3. Creae getter/Setter to expose your properties and assigning them values
4. Create multiple objects and add into a List/Collection
5. Perform operation on collection

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
