AIM:  Create a class Cuboid having default and parameterized constructors. Calculate volume for three objects of class Cuboid instantiated using default and parameterized constructor respectively.

 

CODE:

import java.util.Scanner;

public class Cuboid{

            int length,width,height,volume;

           

            Cuboid(){

                        length=1;

                        width=1;

                        height=1;

            }

            Cuboid(int length, int width, int height){

                        this.length=length;

                        this.width=width;

                        this.height=height;

            }

            void volume(){

                        volume=length*width*height;

                        System.out.println("\nLength: "+length+" Width: "+width+" Height: "+height);

                        System.out.println("Volume of Cuboid is: "+volume);

            }

            public static void main(String args[]){

                        int length,width,height;

                        //non-paramitrized

                        System.out.println("\n First cuboid");

                        Cuboid c1 = new Cuboid();

                        c1.volume();

                       

                        System.out.println("\n Second cuboid");

                        Scanner k = new Scanner(System.in);

                        System.out.print("\nEnter length, width, height of cuboid: ");

                        length=k.nextInt();

                        width=k.nextInt();

                        height=k.nextInt();

                        //paramitrized

                        Cuboid c2=new Cuboid(length,width,height);

                        c2.volume();

                        //paramitrized

                       

                        System.out.println("\n Third cuboid");

                        Cuboid c3 = new Cuboid (42,21,11);

                        c3.volume();

            }

}

Write a program that illustrates interface inheritance. Interface P12 inherits from both P1 and P2. Each interface declares one constant and one method. The class Q implements P12. Instantiate Q and invoke each of its methods. Each method displays one of the constants.
