Take a look at the API for class Object. The Object.toString() method is inherited by your class Fruit. You should override this method and return a more descriptive string representation of your class. Oh yes, the number is the base 16 representation of your object's hashcode.

To get the output you were expecting you should overload your toString method. Add code to your Fruit class that looks like this:
