i have added public void addItem(Product item) { System.out.printf("1 %s ",item.getName());} please help
public class Example {
public static void main(String[] args) {
ShoppingCart cart = new ShoppingCart();
Product pez = new Product("Cherry PEZ refill (12 pieces)");
cart.addItem(pez, 5);
/* Since a quantity of 1 is such a common argument when adding a product to the cart,
* your fellow developers have asked you to make the following code work, as well as keeping
* the ability to add a product and a quantity.
*/
Product dispenser = new Product("Yoda PEZ dispenser");
// Uncomment this line after using method signatures to solve their request in ShoppingCart.java
cart.addItem(dispenser);
}
}
public class ShoppingCart {
public void addItem(Product item, int quantity) {
System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
/* Other code omitted for clarity */
}
public void addItem(Product item) {
System.out.printf("1 %s ",item.getName());
/* Other code omitted for clarity */
}
}
public class Product {
/* Other code omitted for clarity, but you could imagine
it would store price, options like size and color
*/
private String mName;
public Product(String name) {
mName = name;
}
public String getName() {
return mName;
}
}

public class ShoppingCart
public void addItem(Product item, int quantity) {
System.out.printf("Adding %d of %s to the cart.%n", quantity, item.getName());
/* Other code omitted for clarity */
}
public void addItem(Product addedItem) {
addItem(addedItem, 1);
}
}

1,802 Pointsthanks for the reply.but can you explain me how it is accepting 1 in addItem(addedItem, 1)?

66,191 PointsThe one is specifying the quantity of items added in this case one, because only one item need to be added. Don't forget to mark my answer as Best Answer below so people who are having the same issues can also get help.
