Write a public class named "PointXY" with 2 private instance variables named "x" and "y" both of type int. You may add any other functionality to this class you'd like including constructors, methods, and other instance variables.

Write a public method outside of PointXY (in the Problem Set class) named closest_7_15 that takes an ArrayList of PointXY as a parameter and returns the PointXY that is closest to the point (7,15). Use Euclidean distance for distance measurements
