Question

M al you wille to print: • The area of the box if the user gives valid sizes "Invalid size given', otherwise . For example, if the user enters: 'small medium large', the program will print Area of the box is 6 . For example, if the user enters: 'small medium big', the program will print 'Invalid size given LAB ACTIVITY 31.24.1: Chapter 7: Area of a box (Methods) 0/5 Main.java Load default template. 1 import java.util.Scanner; LD DOW N 6 public class Main { public static int convert_to_number(String size) { //Fix this method so that it follows the specifications return -1; 11 // write compute_product here 16 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); Develop mode Submit mode Run your program as often as you'd like, before submitting for grading.

Code:

import java.util.Scanner;

public class Main

{

    //function to return int correspond to the size

    public static int convert_to_number(String size)

    {

        switch (size) {

            case "small":

                return 1;

            case "medium":

                return 2;

            case "large":

                return 3;

            default:

                return -1;

        }   

  }

   

    //function to compute the product, if any of the dimension is negative return -1, else return the product

    public static int compute_product(int length,int width,int height)

    {

        if(length < 0 || width < 0 || height <0)

           return -1;

       

        return length*width*height;

    }

   

    //display the result

    public static void PrintOutput(int product)

    {

        if(product == -1)

                                 System.out.println("invalid size given");

                             else

                                 System.out.println("The area of the box is : " + product);

    }

   

              public static void main(String[] args) {

                             int length, width,height;

                            

                             Scanner scnr = new Scanner(System.in);

                             System.out.print("Please enter the first dimension of a box (small, medium , large) only: ");

                             length = convert_to_number(scnr.next());

                            

                             System.out.print("Please enter the second dimension of a box (small, medium , large) only: ");

                             width = convert_to_number(scnr.next());

                            

                             System.out.print("Please enter the third dimension of a box (small, medium , large) only: ");

                             height = convert_to_number(scnr.next());

                            

                             PrintOutput(compute_product(length,width,height));

                            

              }

}
