how to access static instance variables defined in static initializer block

Hello,

Preparing for the Java exam I have a question about static initializers.
A static initializer block can be used to initialize instance and static va=
riables (http://docs.oracle.com/javase/tutorial/java/javaOO/initial.html). =
So I tried it out and it ended up with this:

//=========================
==========================
===========
package LearnJava;

public class Holder{
    // initialize instance varialbe
    {
        int int1 = 5;
        System.out.println("Initializing instance variable int1: " + int1);
    }
    // initialize static variable
    static {
        int sint1 = 6;
        System.out.println("Initializing static block. sint1: " + sint1);
    }
    // initialize instance varialbe
    {
        int int2 = 7;
        System.out.println("Initializing instance variable int2: " + int2);
    }
    // initialize static varialbe
    static {
        int sint2 = 8;
        System.out.println("Initializing static variable sint2: " + sint2);
    }
=09
    int int1 = 5;
=09
    public Holder(){
    }

    public static void main(String[] args){
        Holder h = new Holder();
        //System.out.println("Running main. sint1: " + Holder.sint1);
        System.out.println("Running main. int1: " + h.int1);
    }
}
//=========================
==========================
===========

I expect to be able to refer to int1, int2 and sint1 and sint2 from an inst=
antiated class and - in the case of the static variables - from the class d=
irectly. But this class does not compile because of line
System.out.println("Running main. sint1: " + Holder.sint1).
Also System.out.println("Running main. sint1: " + h.sint1) doesn't compile.=
 The error is:

 error: cannot find symbol
        System.out.println("Running main. sint1: " + Holder.sint1);
                                                           ^
  symbol: variable sint1
  location: class Holder
1 error

If I comment out this line it compiles and I get output

Initializing static block. sint1: 6
Initializing static variable sint2: 8
Initializing instance variable int1: 5
Initializing instance variable int2: 7
Running main. int1: 5

Q:
Why is the instance variable in the static {} block suddenly unknown? And w=
hy can the instance variable declared in {} be resolved???
Does this mean the static variable scan only be initialized outside any blo=
ck?

Related: When I put static int sint1 = 6; n ieither the constructor or ma=
in() I get an Netbeans error "illegal start of expression" (the line gets =
underlined red and hovering over displays the error). Running te program gi=
ves a dialog "no main classes found"

Thanks,

Marc
