Initialisation steps

[Ravi Prasad]

hi
Can anyone explain why if Line1 is included the class fails to compile (correctly so) but does not complain for Line 2or Line3.
IS the initalisation routine follows the source code and should have given the forward refrence error for line 2 and line3

public class E{
  public static void main(String[] args){
    System.out.println("Starting main");
    E obj = new E(l);
  }
  static{
   System.out.println("In Static initaliser");
  // System.out.println("I is: " + i); [B]//line 1 [/B]
   i = 50; [B]//line 2 [/B]
   l = 30; [B]//line 3 [/B]
  }
 
 E(int m){
   System.out.println(i+ ", " + j + ", " + k + ", " +l + ", " + m);
  }
  {
   System.out.println("In instance initaliser");
   j = 70; l = 20;
  }

 static int i = 5;
 static int l = 3;
 int j = 7;
 int k;
}

Thanks

Hi Ravi
I just compiled this program and it gives error saying
Cant make forward reference to i, j and l.
This is beacuse the static code is initialized first in the order in which it appears.so u cannot make a forward reference.

Hi,
for me alsoThis program complains at line 1,2,3 for forward referencing. so Ravi can u check it again?

Hi Deeksha and Sunita
IF you comment the line 1 then you will not get compile time error and the program will do a correct output. I am using jdk1.3. It's only when you uncomment line 1 you get forward refrencing error.
