Question

Design a class named Person with fields for holding a person's name, address, and telephone number (all as Strings). Write a constructor that initializes all of these values, and mutator and accessor methods for every field.

Next, design a class named Customer, which inherits from the Person class. The Customer class should have a String field for the customer number and a boolean field indicating whether the customer wishes to be on a mailing list. Write a constructor that initializes these values and the appropriate mutator and accessor methods for the class's fields.

Demonstrate the Customer class in a program that prompts the user to enter values for the customer's name, address, phone number, and customer number, and then asks the user whether or not the customer wants to receive mail. Use this information to create a customer object and then print its information.

Program

import java.util.Scanner;

/*Person Class*/
class Person {
   private String name, address, telephone;

   //constructor
   public Person(String name, String address, String telephone) {
       super();
       this.name = name;
       this.address = address;
       this.telephone = telephone;
   }

   //all getters an setters
   public String getName() {
       return name;
   }

   public void setName(String name) {
       this.name = name;
   }

   public String getAddress() {
       return address;
   }

   public void setAddress(String address) {
       this.address = address;
   }

   public String getTelephone() {
       return telephone;
   }

   public void setTelephone(String telephone) {
       this.telephone = telephone;
   }

}

/*Customer class*/

class Customer extends Person {
   private String cnum;
   private boolean mail;

   public Customer(String name, String address, String telephone, String cnum, boolean mail) {
       super(name, address, telephone);
       this.cnum = cnum;
       this.mail = mail;
   }

   public String getCnum() {
       return cnum;
   }

   public void setCnum(String cnum) {
       this.cnum = cnum;
   }

   public boolean isMail() {
       return mail;
   }

   public void setMail(boolean mail) {
       this.mail = mail;
   }
}

/*Driver clas for testing*/
public class Test{
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
      
       String name, address, telephone, cnum, m;
       boolean mail;
      
       //take user input
       System.out.print("Enter Name: ");
       name = sc.nextLine();
       System.out.print("Enter Address: ");
       address = sc.nextLine();
       System.out.print("Enter Telephone number: ");
       telephone = sc.nextLine();
       System.out.print("Enter Customer number: ");
       cnum = sc.nextLine();
       System.out.print("Do you want to receive mails? (Yes/No): ");
       m = sc.nextLine();
       sc.close();
      
       mail = (m.equalsIgnoreCase("Yes"))? true : false;
      
       //creating customer object
       Customer obj = new Customer(name, address, telephone, cnum, mail);
      
       //print customer details
       System.out.println();
       System.out.println("----------Your Details----------");
       System.out.println("Name: "+obj.getName());
       System.out.println("Address: "+obj.getAddress());
       System.out.println("Telephone: "+obj.getTelephone());
       System.out.println("Customer number: "+obj.getCnum());
       System.out.println("Receive mails? "+obj.isMail());
   }
}

Output
