Help with text format

Question

I am attempting to emulate an example in shown in:
http://developer.java.sun.com/developer/Books/gui/swing2/swing2_chap11.pdf
With the following code
fieldFormat = new NameFormat();
JFormattedTextField rField = new JFormattedTextField(fieldFormat);
rField.setColumns(15);
rField.setValue(initialValue);
class NameFormat extends Format {
     public StringBuffer format(Object obj, StringBuffer toAppendTo, FieldPosition fieldPosition) {
          fieldPosition.setBeginIndex(toAppendTo.length());
          String str = obj.toString();
          char prevCh = ' ';
          for (int k=0; k<str.length(); k++) {
               char nextCh = str.charAt(k);
               if (Character.isLetter(nextCh) && prevCh == ' ')
                    nextCh = Character.toTitleCase(nextCh);
               toApendTo.append(nextCh);
               prevCh = nextCh;
          fieldPosition.setEndIndex(toAppendTo.length());
          return toAppendTo;
}I get the following error:
FormattedField.NameFormat should be declared abstract; it does not define parseObject(java.lang.String,java.text.ParsePosition) in java.text.Format
Therefore I determined there must be methods missing. Upon looking I find the following two other methods defines for Format .
formatToCharacterIterator(Object obj) {}
parseObject(String source, ParsePosition pos) {}
The problem is I am unable to determine what the methods should do or look like if added to NameFormat.
Any suggestions or help would be appreciated.
Thanks
