Create a Java application.

Using Luke's Agenda context:

Hand-write in a sheet of paper the method to work on.

1. Find the number of friends whose nationality corresponds to a nationality input as a parameter.
2. Find the number of friends older than an age input as a parameter.
3. Find the youngest friend in the Agenda

We have two classes: Agenda and Friend.

Class Friend has: name -> String, address -> String, phoneNumber -> int, age -> int, nationality -> boolean nationality is considered true if American, false if not.
