A "Point" is a valuable object type for many systems (graphics, engineering, mapping, etc). It's simple yet powerful.
This challenge is to code a basic Point class.
This challenge closely follows the example.

We previously looked at the structure for a class Point.
Note the similarities with the example (Rectangle). Each class has two ivars of type "int".
Add a class "Point" in a file named "Point.java". Type in the code that is shown here.

public class Point {

private int y;
}
Do not add any constructor methods (like example shown here). We'll learn more about these later.
If you don't yet know what a constructor is, that is fine.

public Point(int x, int y) {
this.x = x;
this.y = y;
}
