I'm twisting my brain on this problem, which is probably really
obvious, but I'm stuck.

I have an abstract class X with a static method:

public abstract class X {
  public static void method() {
    ...
  }
}

Class X is extended by many classes, e.g. class Y:

public class Y extends X {
...
}

Now, in a separate (test) class, I have a method that takes for example
class X as parameter, and should call method() on it:

public class Tests extends TestCase {
  public void testMethod(Class<? extends X> clazz) {
    clazz.method(); // Compile error
  }
}

Why can't I call clazz.method()?
I'm probably able to get around it using reflection, but there surely
must be a simpler way?

Hi vidar

Very basic :static method is a property of a class.
It should be called : className.methodName();

If this method is getting overridden by a childClass
then it should again be made static

If you want to call static method of parent class it should be
parentClassName.methodName

for child class
childClassName.methodName

Once again static method is a class property It should be called by
using class name which contains this method
