Name of an int ( e.g. java.sql.Types )

Question

I have the sql.Types code as an int number and want to display the name. Is there a straightforward method or do I have to search it in a loop like here ?
String getName(int i) {
for (Field f: java.sql.Types.class.getFields()) {
     if (f.getType().equals(int.class)) {
          if (f.getInt(f.getType()) == i) {
          System.out.println( i + " = "+f.getName() );
          // e.g.               8 = DOUBLE
          return f.getName();
}This question is not specific to java.sql.Types I guess (that's why I post here).
A dedicated hint for sql is appreciated as well, however ;)

Answer 1

Seems the loop is required and it works (in no time, there aren't too many Fields)
     if (f.getInt(f.getType()) == i) {Having a closer look, I do not understand the inner f.getType() , however.
f.getInt() requires an object, but anything, including null, works ?!
Any hint, or link where to learn about java.lang.reflect.Field, please ?
