Question

Evaluate Grade for Shipping Company - Code in Java

There are many Shipping companies emerging in the market now. 'SaySo' online survey panel has come up with the strategy to choose the best Shipping Company for your shipping needs. The survey panel has taken into consideration two factors of the companies namely the number of countries a shipping Company offers its services (country coverage) and number of shipments done per month. The survey panel has graded the companies based on the two factors as given below:

Grade	Countries	Shipment per month
A	Above 150	Above 1500
B	Above 125	Above 1200
C	Above 100	Above 1000
D	Above 75	Above700
E	<=75 and >=0	<=700 and >=0
Invalid Input	< 0	< 0

Write the program to find the grade under which a specific Company falls, given the number of countries it offers services and the number of shipments made.

Problem Specfication :
The file name should be Main.java.

Input Format :
The first input consists of an integer that corresponds to the number of countries the company offer its services.
The second input consists of an integer that corresponds to the number of shipments per month.

Output Format :
The output should display the Grade of company. Print 'Invalid Input' otherwise.
Refer sample input and output for formatting specifications.

[All text in bold corresponds to input and rest corresponds to output.]
Sample Input and Output 1:
Enter the total number of countries :
150
Enter the total number of shipment per month :
1550
The company grade is : B

Sample Input and Output 2:
Enter the total number of countries :
-12
Enter the total number of shipment per month :
450
Invalid Input

Don'ts:
      1. Do not create packages for classes. Strictly adhere to the program structure given in the template code.
      2. Do not use Internet Explorer, highly recommended to use chrome browser to launch ebox platform.
      3. Do not create multiple classes inside a single file. Create separate file for each class.

Please refer to the screenshot of the code to understand the indentation of the code and output

Code

// Import the Scanner class
import java.util.Scanner;

public class Main{

   public static void main(String[] args) {
  
   // create a number of countries variable
   int countries;
   //create a number of shipment variable
   int shipment;
// Create a Scanner object     
   Scanner myObj = new Scanner(System.in);
   // print the number of countries
   System.out.println("Enter the total number of countries :");
   // take input from user for the number of countries and assign to countries variable
   countries = myObj.nextInt();
   // print the number of shipment to ask the user
   System.out.println("Enter the total number of shipment per month :");
   // take input from user for the number of shipments and assign to shipment variable
   shipment = myObj.nextInt();
  
   // checks if no. of countries entered are greater than 150 and shipment are greater than 1500
   if (countries > 150 && shipment > 1500)
   {
   // prints grade A
   System.out.println("The company grade is : A");
   }
   // checks if no. of countries entered are greater than 125 and shipment are greater than 1200
   else if (countries > 125 && shipment > 1200)
   {
   // prints grade B
   System.out.println("The company grade is : B");
   }
   // checks if no. of countries entered are greater than 100 and shipment are greater than 1000
   else if (countries > 100 && shipment > 1000)
   {
   // prints grade C
   System.out.println("The company grade is : C");
   }
   // checks if no. of countries entered are greater than 75 and shipment are greater than 700
   else if (countries > 75 && shipment > 700)
   {
   // prints grade D
   System.out.println("The company grade is : D");
   }
   // checks if no. of countries entered are greater than or equal to 0 and less than or equal to 75
   //checks if shipment are greater than or equal to 0 and less than or equal to 700
   else if ((countries <= 75 && countries >=0) && (shipment <= 700 && shipment >=0))
   {
   // prints grade E
   System.out.println("The company grade is : E");
   }
   // if none of the above conditions satisfies,it prints Invalid Input
   else
   {
   // prints Invalid Input
   System.out.println("Invalid Input");
   }
  
   }
}

Output

Enter the total number of countries :                                                                                   

160                                                                                                                     

Enter the total number of shipment per month :                                                                          

1509
