ClassCreate a class named Circle. This class will represent a circle and hold its properties and functionalities.In the class Circle, create a double-type variable named radius to represent the circle's radius.Create a method named setRadius that takes a double parameter representing the radius value and assigns it to the radius member variable.Create a method named calculateArea that takes no arguments and returns a double value.Inside the calculateArea method, use the formula area = Math.PI * radius * radius to calculate the area based on the stored radius value.

Main MethodCreate a main method in the same class:This method will be the entry point for your program and allow user interaction.Inside the main method:Create a Scanner object to read user input.Prompt the user to enter the circle's radius using System.out.print.Use the Scanner object's nextDouble method to read the user-entered radius and store it in a variable.Create a Circle object.Call the setRadius method of the Circle object, passing the user-entered radius as an argument.Call the calculateArea method of the Circle object and store the returned area value in a variable.Print the calculated area to the console using System.out.printlnSubmit the following: Screenshot of source code and output, and Java source code file.

Write a function to calculate and return the area of a circle by using the radius of the circle given as a parameter.Notes: Round up the area to 2 decimal places. You can use the round() function. Use pi as 3.14159. You need not take input in this problem, you need to only implement the function provided.

Implement the abstract class Shape with the abstract method calculateArea.Create the derived classes Circle and Rectangle that extend Shape and implement the calculateArea method according to the formulas for each shapeWrite a main program that reads inputs for creating a circle and a rectangle, calculates their areas, and prints the results.Input2 //number of objectsC 10 //Circle with radousR 10 10 //Rectangle with width and height....Output2 lines display the respective area and circumference314.0 62.8100 40Input3C 100R 5 5R 10 10oUTPUT31400.0 62825 20100 40uSE iNHERITANCE WITH ABSTRACT CLASS SHAPE// Find area and Find circumference must be abstract methods Circle and Rectangle should be sub classes

Create a 2 separate Classes CIRCLE  with private data members - Radius and Area, and RECTANGLE with private data members - Length, Breadth and Area. In each of these classes declare and define the member methods putData() [ To display Area ] and computeArea()[ To Compute Area ] are the private and getData() as public member method to read Radius or Length and Breadth based on the choice('C' or 'R'). As a programmer, Write a java program and subsequent pseudocode, to find the area of circle/rectangle using class CIRCLE/RECTANGLE which have following details:getData() to read either radius or lenght and breadth based on the choice 'C' or 'R'Calculate the area using computeArea()Display the Area using putData().Note :Radius is always +Ve, otherwise print "Invalid Radius"Length and Breadth are +Ve, otherwise print "Invalid Length(if Length is -VE) or Invalid Breadth(if Breadth is -VE) or "Invalid Length and Breadth"Input : First line Read the type ('C'  or 'R')Second line onwards read Radius(if Type = 'C') or Length and Breadth (if Type = 'R')Output :  print Area

Create an abstract class named shape that contains two integers and an empty method named printarea().Provide three classes named rectangle, triangle and circle such that each one of the classes extends the class Shape. Each of the inherited class from shape class should provide the implementation for the method printarea(). Get the input and calculate the area of rectangle, circle and triangle.In the Main class, create the objects for the three inherited classes and invoke the methods and display the  area values of the different shapes.2(length of rectangle)3(breadth)5(triangle breadth)6(Triangle height)4(circle radius)
