812 PointsCompiler error
I've reached end of file while parsing and don't know how many brackets I need. If I add two or one the compiler says error! Don't know what else to do! 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 the line following this comment,
after adding a new method using method signatures,
to solve their request in ShoppingCart.java
*/
// cart.addItem(dispenser);
public class shoppingCart{
public void addItem(Product item, int quantity){
quantity = 1;
System.out.printf("Adding %d of %s to the car. %n", quantity, item.getName());
/* other code ommitted for clarity */
}
public void addItem(Product item)
{
addItem(item,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 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;
}
}

Treehouse TeacherI think you're error starts from here:
public class shoppingCart{
Looks like you accidentally left that in place. Did Jon's message help you?

Courses Plus Student 7,254 PointsHi April,
It looks like things got a little mixed up. I will post the original code from the question and then show you how to solve it.
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);
}
}
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 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;
}
}
So with what's written, there is a method in your ShoppingCart class that is called addItem() that takes two parameters. A Product called item and an int called quantity. This is the product you add to your shopping cart as well as the amount of that product you want to add.
It is common to only want to add one of a product to a shopping cart, so it is requested of you to make a new method that does this.
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 item) {
addItem(item, 1);
}
}
What we've done above is add a method called addItem() except this time it only takes one parameter, which is a Product called item. This method calls the other addItem() with two parameters and passes in the same product as well as the number 1. This is a simple way to add a "default" value of 1.
To test the method you uncomment the line in your Example.java file
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);
}
}
