Question

I have a simple question. Is there a way ( using reflections I suppose ) to iterate all the static values of a class?

For instance

class Any {     static int one = 1;     static int two = 2;     static int three = 3;      public static void main( String [] args ) {           for( int i : magicMethod( Any.class ) ){               System.out.println( i );           }     }  } 

Output

 1  2  3 

Thanks.
