Question

[JAVA] Write a class "customer" that has data fields "name" and "lastName." In addition, the accessor methods "get name" and "get last name" should print out the customer name. The class should contain a nested class CreditCard that has a single method "pay." The CreditCard method "pay" should print "Paid." The customer class constructor should take in parameters "name" and "last name." The customer class should have a method "pay" that calls the nested class pay method. Create a test customer class that instigates the constructor and then calls the pay customer method.

Answer 1

Here I am providing the answer for the above question:

Customer.java :

Code:

package progrmas;

public class Customer
{
   String name;
   String lastName;
   public String getName() //get name
   {
       return name;
   }
   public String getLastName() //get lastname
   {
       return lastName;
   }
  
   public Customer(String name,String lastName)
   {
       this.name=name;
       this.lastName=lastName;
   }
  
   class CreditCard //nested class
   {
       void pay() //pay method in CreditCard class
       {
           System.out.println("Paid");
       }
   }
  
   public void pay() //pay method in customer calss
   {
       CreditCard c1= new CreditCard();
       c1.pay();
   }
}
Screenshot:

TestCustomer.java :

package files;

public class TestCustomer
{
   public static void main(String args[])
   {
       //creating customer object to test
       Customer c = new Customer("Swetha","Koluboyina");
       //calling pay customer method
       c.pay();
   }
}
