Question

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90 Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west. Ex: If the input is: 90 the output is: The 90 is primary, going east/west. Ex: If the input is: 290 the output is: The 290 is auxiliary, serving the 90, going east/west Ex: If the input is G here to search The 290 is auxiliary, serving the 90, going eas Ex: If the input is: 0 or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.

Answer 1

Answer:

The Java code is given below with appropriate variable names and tags for better understanding

Explanation:

import java.util.Scanner;

public class LabProgram{

   public static void main(String[] args) {

       Scanner scnr = new Scanner(System.in);

       int highwayNumber;

       int primaryNumber;

       highwayNumber = scnr.nextInt();

       if(highwayNumber<1 || highwayNumber>999)

           System.out.println(highwayNumber+" is not a valid interstate highway number.");

       else{

           if(highwayNumber>=1 && highwayNumber<=99){

               System.out.print("The "+highwayNumber+" is primary, going ");

               if(highwayNumber%2==1)

                   System.out.println("north/south.");

               else

                   System.out.println("east/west.");

           }

           else{

               primaryNumber = highwayNumber%100;

               System.out.print("The "+highwayNumber+" is auxillary, serving the "+primaryNumber+", going ");

               if(primaryNumber%2==1)

                   System.out.println("north/south.");

               else

                   System.out.println("east/west.");

           }

       }

   }
