Need help with the following java problem:

Suppose you own a computer store that sells two different types of products: desktop computers and laptops. These products can be described using the following attributes: ? Desktops have a processor, RAM, hard drive, and video RAM.

The cost for a desktop1 is calculated like this: base price of $150 + $6.50*(RAM in GB) + $0.15*(hard drive space in GB) + $0.48*(VRAM in MB) ?

Laptops have a processor, RAM, hard drive, and screen size. The cost for a laptop is calculated like this: base price of $300 + $8.00*(RAM in GB) + $0.19*(hard drive space in GB) + $13.83*(screen size in inches)

1. Design and implement the following class hierarchy. All classes should have appropriate constructors.

a. An abstract class Computer that contains as many common elements as possible for both desktops and laptops. It should also contain an abstract getCost() method.

b. Two concrete subclasses of Computer named Desktop and Laptop Both Desktop and Laptop should have toString methods that return information on their type (desktop or laptop), individual components, and cost. Desktop and Laptop should also override the abstract getCost() method with the appropriate calculation.

2. Write a client program that creates an array of at least 5 Computer objects. The array should include both desktops and laptops.

The program should then sort this array by cost (take advantage of the Comparable interface and the sort method for Comparable objects that we discussed in class!), and display the final list of computers sorted by ascending cost.

Note that there should be one array containing all of the computers, not two arrays with the desktops and laptops separately.
