Call protected method from a subclass of another instance of different packages
Don’t know the rationale, but JLS confirms this in 6.6.2. Details on protected Access (emphasis mine): A protected member or constructor of an object may be accessed from outside the package in which it is declared only by code that is responsible for the implementation of that object. So: package P2; public class P2 { … Read more
Java: Use import or explicit package / class name?
There is no real difference; the generated byte code will be exactly the same. An import statement is really just a way to tell the compiler “when I write JFrame, I actually mean javax.swing.JFrame“.

How to embed the GNU Octave in C/C++ program?

URLClassLoader and accessibility of package-private methods
A class at runtime is identified by both its fully qualified name and its ClassLoader. For example, when you test two Class<T> objects for equality, if they have the same canonical name but were loaded from different ClassLoaders, they won’t be equal. For two classes to belong to the same package (and in turn being … Read more
