In java, there's three levels of access: Public - Open to the world Private - Open only to the class Protected - Open only to the class and its subclasses (inheritance). So why does the java compiler allow this to happen? TestBlah.java: public class TestBlah { public static void main(String[] args) { Blah a = new Blah...
I am currently writing a CMS and remember someone (it might have been on here) criticise the existing CMS for not having a robust enough user permissions system.

A common misconception about access level in Java, C#, C++ and PHP is that it applies to objects rather than classes. That is, that (say) an object of class X can't see another X's private members. In fact, of course, access level is class-based and one X object can effortlessly refer to the private members of another. Does there exis...

If I have a class with a method I want protected and internal. I want that only derived classes in the assembly would be able to call it. Since protected internal means protected or internal, you have to make a choice. What do you choose in this case - protected or internal? ...
Now if you read the naming conventions in the MSDN for C# you will notice that it states that properties are always preferred over public and protected fields. I have even been told by some people that you should never use public or protected fields. Now I will agree I have yet to find a reason in which I need to have a public field bu...
