use an array of objects for 5 different rectangles make a UML you have to upload 3 files as submissions for this assignment. (or you can submit a link to an online compiler such as "replit" that includes all these 3 files) class (.h)

1)Create a complete Java class that can be used to create a Computer object as described below:A Computer has a:- Manufacturer- Disk Size- Manufacturing Date- Number of coresa) Add all instance variables (data encapsulation is expected).b) The class must have getters and setters for all instance variables.c) The class must have two constructors: a no-arg constructor and a constructor thatreceives input parameters for each instance variable.d) Implement a toString() method for your class.     2)Write a Java program TestComputer, which creates three Computer objects with the informationbelow:a) - Manufacturer: Dell- Disk Size: 1189160321024 bytes- Manufacturing Date: April 1, 2020- Number of cores: 2b) - Manufacturer: Apple Inc- Disk Size: 269283712040 bytes- Manufacturing Date: March 31, 2020- Number of cores: 4c) Create your own Object. You can mimic your actual personal computer or use a no-argsconstructor.Print the three objects using toString() method to show all data fields

PLEASE CODE IN PYTHON PLEASE USE THE CLASS FUNCTION    A sphere is a geometric shape that could be compared to a ball. Create an Sphere class given the following design:    A sphere has a radius, referred to as r, which extends from the center to the surface.  The volume of a sphere is computed as  4πr^3/3  The surface area of a sphere is computed as 4πr2 Write appropriate client code to test the class.
