What happens when you try to compile / run the fol

What happens when you try to compile / run the following code:


abstract class Animal {
    static {
        System.out.println("Inside Animal");
    }
}

class Cat extends Animal {
    static {
        System.out.println("Inside Cat");
    }
}

class Dog extends Animal {
    static {
        System.out.println("Inside Dog");
    }
}

public class Main {
     public static void main(String[] args){
          Animal cat = new Cat();
          Animal dog = new Dog();
     }
}

Explanation

The static initialization block is called only once when the class is loaded. Oracle Press - Sun Certified Java Programmer Study Guide (2005) page 226
