Part 1

Create an Interface called Printable, that defines 3 methods: toString() and display() and printToFile() [10 points]

Update your class from your previous assignments to have the following

Implement the Comparable Interface [5 points]

Override to compareTo() method - (I'ts up to you to determine the best way to sort your objects) [20 points]

Implement the Printable interface - You will also need to implement all the methods, some of which you should already have. The printToFile() method should just simply print your data to a text file.[10 points]

In the driver class (the class with your main method), define your own generic static method called maxHighest()

It should have 3 generic parameters [10 points]

It will return the max highest item (based on their sorting order) of the 3 parameters [10 points]

In your main method, test the maxHighest() method by passing the following objects to it. It should print out the some text describing it as the 2nd highest item:

3 Strings [5 points]

3 Integers [5 points]

3 Objects of your Class from your previous assignments [5 points]
