 ## Introduction
 
-The countries of the world have many different defining attributes including land size, population, and median age. Below is a list of countries to include in your data. As most people do their research using websites, we are going to create web services to help search this data. We will be returning JSON objects. Nothing fancy for now!

 Some Important Notes That Might help:
 
 * The sort method must work with `int` - so not `long`. the solution - type casting! See the code snippet below:  
-      `.sort((c1, c2) -> (int)(c1.getPopulation() - c2.getPopulation()))`
-* To calculate median for stretch goals - if the list contains an odd number of items, pick the middle one. If the list contains an even number of items, pick either of the two items that lie in the middle.
