Spring Beans and Dependency Injection - Part 3

Writing Classes.

We will write the three Classes - Cart, Shop and Checkout.

In your /src/org/confucius, create a class Cart.java, like this:

 package org.confucius;  
   
 public class Cart {  
      private int numItems = 0;  
   
      public int getNumItems() {  
           return numItems;  
      }  
   
      public void setNumItems(int numItems) {  
           this.numItems = numItems;  
      }  
 }  
   

In your /src/org/confucius, create a Class Shop.java, like this:

 package org.confucius;  
   
 public class Shop {  
      private Cart cart = null;  
   
      public Cart getCart() {  
           return cart;  
      }  
   
      public void setCart(Cart cart) {  
           this.cart = cart;  
      }  
 }  
   

In your /src/org/confucius, create a Class Checkout.java, like this:

 package org.confucius;  
   
 public class Checkout {  
      private Cart cart = null;  
   
      public Cart getCart() {  
           return cart;  
      }  
   
      public void setCart(Cart cart) {  
           this.cart = cart;  
      }  
 }
