Annotation Type LazyInit

@Retention(value=RUNTIME)
 @Target(value=FIELD)
public @interface LazyInit

Use this annotation on any static or field that will be initialized lazily, where races yield no semantic difference in the code. The canonical example of this is String.hashCode():

 public int hashCode() {
   int h = hash;
   if (h == 0 && value.length > 0) {
     char val[] = value;

     for (int i = 0; i < value.length; i++) {
       h = 31 * h + val[i];
     }
     hash = h;
   }
   return h;
 }
