Textual order of static variables and initialization order in Java -

i spend 5 minutes find duplicate in so.

my question simple. following code work?

public class lexicalorderstatic {     private static integer a1 = inita1();      private static integer a2 = inita2();       private static integer inita2(){         return new integer(5) / a1;     }      private static integer inita1(){         return new integer(5);     }      public integer geta1(){         return new integer(a2);     }      public static void main(string[] args) {         lexicalorderstatic lexluthor = new lexicalorderstatic();         system.out.println(lexluthor.geta1());      } } 

in java can sure a1 always initialized before a2 ?

thanks. dw ok if asked or if simple.

in java can sure a1 initialized before a2 ?

yes, because specification (section 12.4.2) guarantees (emphasis mine):

next, execute either class variable initializers , static initializers of class, or field initializers of interface, in textual order, though single block.

note constants initialized earlier non-constants (step 6 compared step 9 quoted above).
