You post code by wrapping ```java and ``` around your Java code.
Example:
```java
public class Hello {
public static void main(String[] args) {
System.out.println("Hello!");
}
}
```
(sorry as you see it it very hard to format code here)
The output will be (when you post your answer/comment):
// Watch out! This isn't the code that will pass the challenge,
// I'm just giving a demonstration on how to post code in the forums.
/*
-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/
DON'T USE THIS CODE IN CHALLENGE!
-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/

public class Hello {
public static void main(String[] args) {
System.out.println("Hello!");
}
}
Thanks for understanding :)

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 the line following this comment,
after adding a new method using method signatures,
to solve their request in ShoppingCart.java
*/
cart.addItem(dispenser); //remove comments <-----------------------------------------
}
}
Step 2. Add a new method called addItem that only takes a Product object as the parameter. Then you call the original addItem method while passing a quantity of 1.
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. Please imagine
lots and lots of code here. Don't repeat it.
*/
}
public void addItem (Product productItem) {
addItem(productItem, 1);
}
}
This is often done in programs and is called method overloading. You can read about it by Googling "Java method overloading".
