Answer:

Explanation:

import java.io.*;

public class Driver

{

public static void main(String[] args) throws IOException

{

BufferedReader br = new BufferedReader(new InputStreamReader(System.in)) ;

Cube c=new Cube(); //creating objects for all classes

Cuboid cd=new Cuboid();

Sphere s=new Sphere();

Cylinder cr=new Cylinder();

System.out.println("1. Cube"); //user input

System.out.println("2. Cuboid");

System.out.println("3. Sphere");

System.out.println("4. Cylinder");

System.out.println("enter your choice:"); //choice reading

int a= Integer.parseInt(br.readLine());

switch (a) //actions based on choice

{

case 1:

System.out.println("Enter value for side:");

Float side= Float.parseFloat(br.readLine());

System.out.println("The surface area for cube is=" + c.surfaceArea(side));

System.out.println("The volume of cube=" + c.volume(side));

break;

case 2:

System.out.println("Enter value of length:");

float length= Float.parseFloat(br.readLine());

System.out.println("Enter value of breadth");

Float breadth= Float.parseFloat(br.readLine());

System.out.println("Enter value of height:");

Float height= Float.parseFloat(br.readLine());

System.out.println("Surface area of cuboid is=" + cd.surfaceArea(length,breadth,height));

System.out.println("volume of cuboid is=" + cd.volume(length,breadth,height));

break;

case 3:

System.out.println("Enter value for radius:");

Float radius= Float.parseFloat(br.readLine());

System.out.println("The surface area for Sphere is=" + s.surfaceArea(radius));

System.out.println("The volume of Sphere=" + s.volume(radius));

break;

case 4:

System.out.println("Enter value for radius:");

float radius1= Float.parseFloat(br.readLine());

System.out.println("Enter value for height:");

float height1= Float.parseFloat(br.readLine());

System.out.println("The surface area for Sphere is=" + cr.surfaceArea(radius1,height1));

System.out.println("The volume of Sphere=" + cr.volume(radius1,height1));

break;

case 5:

System.exit(0);

default:

System.out.println("Invalid Entry!");

}

}

}

class Cube

{

public float surfaceArea(float side) //surface area calculation

{

return 6*side*side;

}

public float volume(float side) //volume calculation using formula

{

return (side*side*side);

}

}

class Cuboid

{

public float surfaceArea(float length,float breadth,float height)

{

return (2*((length*breadth)+(breadth*height)+(height*length))) ;

}

public float volume(float length,float breadth,float height)

{

return (length*breadth*height );

}

}

class Cylinder

{

public float surfaceArea(float radius,float height)

{

return (2*22/7*radius*height );

}

public float volume(float radius,float height)

{

return (22/7*radius*radius*height );

}

}

class Sphere

{

public float surfaceArea(float radius)

{

return 4/3*22/7*radius*radius ;

}

public float volume(float radius)

{

return (4/3*22/7*radius*radius*radius );

}

}
