Each instance of this class represents a location on a two-dimensional plane. A Pos object is essentially a pair of two coordinates, x and y. Pos objects are immutable.
This class has an alias in the top-level package o1, so it’s accessible to students simply via import o1.*.
Parameters
- x
-

Pos - y

Pos
