Fields are + * identified by constants, whose names typically end with <code>_FIELD</code>, + * defined in the various subclasses of <code>Format</code>. See + * <code>ERA_FIELD</code> and its friends in <code>DateFormat</code> for + * an example. + * + * <p> + * <code>FieldPosition</code> keeps track of the position of the + * field within the formatted output with two indices: the index + * of the first character of the field and the index of the last + * character of the field. + * + * <p> + * One version of the <code>format</code> method in the various + * <code>Format</code> classes requires a <code>FieldPosition</code> + * object as an argument.
