    Please don't double post. The answer to this question is staring you in the face, and I'm not sure why you can't see it. Stare at this line:

    System.out.println(A.a);

    until you can answer the question, "What does it do?"

    Since you have seen what it does, the answer should come to you quickly.

    Your latest comments make me think I didn't understand your question.

    Compare the results of your example to mine below and see if that clears up your confusion. The key is to know when the static initialization block (or "static block" as you called it) will be executed.
    class A
    {
        static final int a=10;
     
        static
        {
            System.out.println("56");
        }
     
        public A()
        {
            System.out.println( "In A" );
        }
    }
     
    public class StaticTest
    {
        public static void main(String[] args)
        {
            System.out.println( A.a );
     
            new A();
        }
    }
