Can a class call its own method?
A class may contain its own constants, variables (called “properties”), and functions (called “methods”). The pseudo-variable $this is available when a method is called from within an object context. $this is the value of the calling object. Calling a non-static method statically throws an Error.

How to create public method outside of public class?
The objective is to write code to determine the closest x,y coordinate to (24,5). Using a public class PointXY with 2 instance variables. Then a public method outside of the class that returns the point closest to (24,5). I know I’m not doing it right as the ArrayList of type PointXY is confusing me. Thank you help in advance.
Is there way to declare private class in SomeClass?
It would be meaningful in this scenario; you have a public class SomeClass, inside which you want to encapsulate some functionality that is only relevant to SomeClass. You could do this by declaring a private class ( SomePrivateClass in my example) within SomeClass, as shown below.
Do you make all methods in stake public?
Instead of making all methods to be tested public, and instead of redesigning your classes completely, sometimes the most pragmatic solution is to make the methods in stake “internal” and use the “InternalsVisibleTo” attribute to allow your unit tests access them.
What does it mean to have private implementation of base class?
This allows one to provide a private (or protected or internal) implementation of a public interface or base class. The consumer need not know nor care about the concrete implementation. This can also be done without nested classes by having the MySpecialEnumerator class be internal, as you cannot have non-nested private classes.
