Question

Write a program for XXX Phones, a provider of cellular phone service. Prompt a user for maximum monthly values for talk minutes used, text messages sent, and gigabytes of data used, and then recommend the best plan for the customer’s needs. A customer who needs fewer than 400 minutes of talk and no text or data should accept Plan A at $29 per month. A customer who needs fewer than 400 minutes of talk and any text messages should accept Plan B at $35 per month. A customer who needs 400 or more minutes of talk and no data should accept either Plan C for up to 100 text messages at $45 per month or Plan D for 100 text messages or more at $50 per month. A customer who needs any data should accept Plan E for up to 2 gigabytes at $59 or Plan F for 2 gigabytes or more at $65. Save the file as CellPhoneService.java

Again, Don’t forget to create the application/project CellPhoneServiceTest.java Class that has the main method and an object to use the CellPhoneService class.

I need the CellPhoneServiceTest.java to have the main method and all the objects in the CellPhoneService.java. The CellPhoneServiceTest.java should call the information from CellPhoneService.java with CellPhoneService c = new CellPhoneService();

Answer 1

Code is Given Below:

=========================

CellPhoneService.java

============================

public class CellPhoneService {
   //declaring variable to hold minutes,messages and data
   int minutes;
   double data;
   int message;
  
  
   //this method will find best plan to print details
   public void getBestPlan() {
       //checking for best plan
       if(minutes<400 && data==0 && message==0) {
           System.out.println("Best Plan For you is A at $29 only");
           return;
       }
       if(minutes<400 && message>0 && data==0) {
           System.out.println("Best Plan For you is B at $35 only");
           return;
          
       }
       if(minutes>=400 && message<=100 && data==0) {
           System.out.println("Best Plan For you is C at $45 only");
           return;
       }
       if(minutes>=400 && message>100 && data==0) {
           System.out.println("Best Plan For you is D at $50 only");
           return;
          
       }
       if(data<=2) {
           System.out.println("Best Plan For you is E at $59 only");
           return;
       }
       if(data>2) {
           System.out.println("Best Plan For you is F at $65 only");
           return;
       }
      
   }

}

CellPhoneServiceTest.java

===========================

import java.util.Scanner;

public class CellPhoneServiceTest {
   public static void main(String[] args) {
       //creating scanner object to get data from user
       Scanner scn=new Scanner(System.in);
       //asking user to enter data
       System.out.print("Enter maximum monthly values for talk minutes used: ");
       int minutes=scn.nextInt();
       System.out.print("Enter maximum monthly values for text messages sent: ");
       int message=scn.nextInt();
       System.out.print("Enter maximum monthly values for gigabytes of data used: ");
       double data=scn.nextDouble();
       //creating cell phone service object
       CellPhoneService c=new CellPhoneService();
       //setting data to object
       c.minutes=minutes;
       c.message=message;
       c.data=data;
       //calling getBestPlan method
       c.getBestPlan();
   }

}

Output:
