UPDATE: This question was the subject of my blog in September 2014. Thanks for the great question! There is considerable debate on this question even within the compiler team itself. First off, it’s wise to understand the rules. A public member of a class or struct is a member that is accessible to anything that … Read more
dogList is local to the method Main. What you want to do instead is to place dogList outside of that scope. public class Program { static List<Dog> dogList = new List<Dog>(); … Alternately you can send the list into your add method.
Your property is an instance variable, so the value can be different across different instances of Form1. If you are trying to access instance variables from a parent form, the easiest way to do that is to pass Form1 in to the constructor of Form2. public partial class Form2 : Form { private Form1 f1; … Read more
You can’t use expressions when declaring class properties. I.e. you can’t call something() here, you can only use static values. You’ll have to set those values differently in code at some point. Like any other PHP static variable, static properties may only be initialized using a literal or constant; expressions are not allowed. So while … Read more
Except that, if you try to use $this in your method, like this : class t { protected $a = 10; public function tt() { echo $this->a; echo 1; } } t::tt(); You’ll get a Fatal Error when calling the non-static method statically : Fatal error: Using $this when not in object context in …\temp.php … Read more

To be honest, you have painted yourself into a corner here. If classes A and B are not related and not members of the same package, then visibility won’t solve the problem. (And even if it did, reflection can be used to subvert the visibility rules.) Static code analysis won’t solve the problem if the … Read more
Actually you can execute the main method in a non-public class. if you put this class class A { public static void main(String… args) { System.out.println(“This is not a public class!”); } } in a file named NonPubClass.java. You can compile this file using javac command but you will not get a NonPubClass.class, you will … Read more
If B inherits from A using public, can B override one of the functions and force it to be private? NO Eventhough the my_func1() is declared under priavte access specifier it can be still called through a pointer to class A, actually pointing to a object of class B The call to my_func1() is evaluated … Read more
There really is no equivalent construct in Ruby. However, it looks like you are making one of the classic porting mistakes: you have a solution in language A and try to translate that into language B, when what you really should do is figure out the problem and then figure out how to solve it … Read more
