    System.out.println("x = " + x);

    System.out.println("a = " + a);

    System.out.println("b = " + b);

  

  }

  static 

  {

    System.out.println("Static block initialized.");

    b = a * 4;

  }

  

  

  public static void main(String args[])

  {

    meth(42);

    meth(4);

    meth(0);

  }

}

Output:
