this feature is 'Class Literals' and the concept is 'reflection', there is a package java.lang.reflect, but some methods are declared in Object. You can use it if you are exploring class or checking an unknown object, e.g. if you get it as a parameter in a method or at debug time, or if you are writing a program that displays the properties of objects eg IDE or with JSON import java.lang.reflect.Method; public class Program { public static void main(String args[]) { printMethods( String.class ); } static void printMethods(Class<?> c){ for (Method m: c.getMethods() ) System.out.println(m.getName() +"()"); } }

class with name 'Class' (java.lang.Class<T>) is special class for to get an informations about classes in your code. this program detects . if class 'Simple' is interface (false) . if class 'My' is interface (true) then assigns Class type object which represent B class to c2

yes, it returns Class<B> type object try c2 = new B(); B is class, there is no new B() for create object of type B, but internally there is created object which stores informations about class B and you can get reference to it by B.class construct
