DataNode is a fundamental data structures model type. It is simply a node that holds data (has an instance variable "data").

DataNode is a simple key-value object:

DataNode
	data

The instance variable (ivar) is "data".

Coding requirements:

Write a class that uses a generic type parameter "T" specified on the class that specifies the value type for ivar "data"
Write a constructor that receives values to set all ivars
Write a getter for each ivar

Hints

You only need one ivar, one constructor, and one instance method for the DataNode class

Testing Problem Statement

Also reference the Association test write-up as needed.

Write code to test the model. If you get stumped, look at test code solution.

Test Code Solution

First, try to write test code yourself. Then review and compare the following for possible ideas.

Here is support code that is needed for the test code.

Note that this support code is just one example of a minimal testing framework. Feel free to build your own.
