@abhishek, when you use multiple static keyword/block usages, JVM combines all of them into one big static block and then executes it. In your example static InitClass3 variable is already defined due to the fact that they're in the same block. This usage is exactly same with:

static { .. public static InitClass3 refInitClass3= new InitClass3(2); System.out.println(”Hello You1″); refInitClass3= new InitClass3(1); System.out.println(”Hello You2″); .. }

Hope it helps.

why this works (compiles) , even if the variable in static is yet not declared:

public class StaticTest {


static 

{

    System.out.println("Hello You1");

    refInitClass3= new InitClass3(1);

    System.out.println("Hello You2");       

}       

public InitClass2 refInitClass2= new InitClass2();  



public static InitClass1 refInitClass1= new InitClass1();



public static InitClass3 refInitClass3= new InitClass3(2);



public static void main(String[] args) {



    StaticTest refStaticTest = new StaticTest();

}

}
