The validateJeroo() method takes in an array of Jeroo objects and could throw two different exceptions. If a Jeroo in the array is null, it will throw an IllegalArgumentException. If a Jeroo is facing North, it will throw an IllegalstateException. Add two catch clauses to the try block in the method to: Return -1 if any Jeroos are null, or return -2 if any Jeroo is facing North. The method already returns 0 on normal operation.

The following code runs a method called validateUser() that will throw an IllegalArgumentException if a username (passed in as a parameter) is less than three letters long. This method will not return any value and will do nothing if no error is thrown. Below, a try/catch block has been implemented to make the username longer than 3 characters if it is too short. Add in a finally block to add "user" onto the end of each user name.
