-1. Create a `Payment` interface
+## Part 1 - com.zipcoder.payment.Payment
+1. Create a `com.zipcoder.payment.Payment` interface
   - The class should define a `getId()` method which returns a Long
   - The class should define a `getPayerName()` method which returns a String
   - The class should define a `getShortDescription` method which returns a String

-2. Create a `CreditCard` class which implements the `Payment` interface
+1. Create a `com.zipcoder.payment.CreditCardTest` test class
+2. Create a `com.zipcoder.payment.CreditCard` class which implements the `com.zipcoder.payment.Payment` interface

 # Section 2 - Comparable
 Note: You may use the String/Long compareTo methods in your code
-1. Edit the `Payment` class to extends the Comparable interface
-  - `public class Payment extends Comparable<Payment>`
+1. Edit the `com.zipcoder.payment.Payment` class to extends the Comparable interface
+  - `public class com.zipcoder.payment.Payment extends Comparable<com.zipcoder.payment.Payment>`
   - This indicate that payment can be comparable, which means it can be sorted
-2. Fix the syntax error in your CreditCard, Check, and Paypal class by adding the compare method
+2. Fix the syntax error in your com.zipcoder.payment.CreditCard, Check, and Paypal class by adding the compare method
 3. Create a test for the `compareTo` method. Compare using the getShortDescription()
-  - Example: Given Payment of type Paypal with the short description of `Paypal Tia Mowry tia@mowry.com` and a Check with the short description of `Check Tia Mowry ***4551`, then the `compareTo` method should return a number larger than 0
+  - Example: Given com.zipcoder.payment.Payment of type Paypal with the short description of `Paypal Tia Mowry tia@mowry.com` and a Check with the short description of `Check Tia Mowry ***4551`, then the `compareTo` method should return a number larger than 0
   - The `compareTo` method will return number larger than 0 if this payment comes after payment2
   - The `compareTo` method will return number 0 if this payment has the same information
   - The `compareTo` method will return number less than 0 if this payment comes before payment2
 4. Add the code necessary to make the test pass
 5. Create a new `PaymentSortByPayer` class which implements `java.util.Comparator`
   - This class will sort by payer name
-  - `public class PaymentSortByPayer implements Comparator<Payment>`
+  - `public class PaymentSortByPayer implements Comparator<com.zipcoder.payment.Payment>`
 6. Add the required `compare` method from the Comparator
 7. Create a test to compare two payment
