Question

8. Complete the program that calculates the volume of a cube. If the side length entered for the cube is negative, the program should display an error message saying the length should be positive. If the side length entered for the cube is greater than 100, the program should print a message saying the side is too big. Otherwise the program should calculate and print the volume of the cube of the given side length.

Sample program runs are shown below: import java.util.Scanner; public class CubeVolume { public static void main(){ Scanner reader = new Scanner(System.in); System.out.print("Enter the cube side length: "); double side = reader.nextDouble();

Answer 1

Java code(The given code is in java):

import java.util.Scanner;
public class CubeVolume{
    public static void main(String[] args){
        Scanner reader=new Scanner(System.in);
        //accepting cube side length
        System.out.print("Enter the cube side length: ");
        //reading it
        double side=reader.nextDouble();
        //checking if it is negative
        if(side<0)
            //printing it should be positive
            System.out.println("The length should be positive.");
        //checking if length of the side is 100
        else if(side>100)
            //printing side is too big
            System.out.println("The side is too big.");
        else
            //printing volume
            System.out.println("The volume of cube of length "+side+" is "+(side*side*side));
   }
}
