Practice for inheritance Create a class circle and use inheritance to create another class cylinder from it Create a class rectangle and use inheritance to create another class cuboid, try to keep it as close to the real-world scenario as possible (for your practice)  Create a method for area and volume in 1  create methods for area & volume in 2 and also create getters and setters  What is the order of constructor execution for the following inheritance hierarchy  Code: package Com.Suryawanshi ; class Circle{ int radius ; public int getRadius () { return radius ; } public void setRadius ( int radius) { this . radius = radius ; } Circle (){ System. out .println( "I am Non Parametrized Constructor" ) ; } Circle ( int r){ this . radius =r ; } public double circleArea (){ return Math. PI * this . radius * this . radius ; } } class Cylender extends Circle{ int height ; public ...

  Create a class Game, which allows a user to play the "Guess the Number" game once. The game should have the following methods: Constructor to generate the random number takeUserInput() to take a user input of a number isCorrectNumber() to detect whether the number entered by the user is true getter and setter for noOfGuesses Use properties such as noOfGuesses(int), etc to get this task done! Code: package Com.Suryawanshi ; import java.util.Random ; import java.util.Scanner ; class Game{ public int number ; public int inputNumber ; public int noOfGuesses ; public int getNoOfGuesses () { return noOfGuesses ; } public void setNoOfGuesses ( int noOfGuesses) { this . noOfGuesses = noOfGuesses ; } Game (){ Random rand = new Random() ; this . number = rand.nextInt( 100 ) ; } void takeUserInput (){ System. out .println( "Guess the Number" ) ; Scanner sc = new Scanner(System. in ) ; ...

  The Point class represents a point with x and y coordinates. Create a class Point according to the class diagram given below: InputP1(x,y)=2,3 InputP2(x,y)=5,6 Output Should be: The distance of P1 from Origin is 3.605551275463989 The distance of P1 from P2 is 4.242640687119285 Code: package Com.Suryawanshi ; class Point{ private double x ; private double y ; public double getX () { return x ; } public void setX ( double x) { this . x = x ; } public double getY () { return y ; } public void setY ( double y) { this . y = y ; } public Point ( double x , double y) { this . x = x ; this . y = y ; } public double distance (){ return Math. sqrt (( this .getX())*( this .getX())+ ( this .getY())*( this .getY())) ; } public double distance (Point point){ return Math. sqrt (( this .getX()-point.getX())*( this .getX()-point.getX())+ ( thi...

  (Note: comments code and then run for each problem.) Problems- 1. Create a class Employee with the following properties and methods: Salary (property) (int) getSalary (returning int) name(property) (String) getName(Reurning String) setName(changing the name) 2. Create a class cellphone with methods to print ringing..., vibrating...., and calling friends....etc. 3. Create a class with a method to initiate its side, calculating area, perimeter, etc.  ------------------------------------------------------------------------------------------------------------------- Code: package Com.Suryawanshi ; class Employee{ int Salary ; String name ; public int getSalary (){ return Salary ; } public String getName (){ return name ; } public void setName (String n){ name = n ; } } class CellPhone{ public void ring (){ System. out .println( "Ringing........" ...
