Can't parse File and Handler in SAXParser

Question

I'm passing in an XML file and a handler to the SAXParser but I'm getting this error:

The attributes for the parse method are defined as (File, DefaultHandler) which match exactly, so I'm not sure where I'm going wrong. Here is the full method:

public String readXML (File readFile) throws Exception {
    SAXParserFactory saxFactory = SAXParserFactory.newInstance();
    SAXParser saxParser = saxFactory.newSAXParser();
    final String outputString = "";
    DefaultHandler handler = new DefaultHandler() {
        boolean bArtist    = false;
        boolean bAlbumName = false;
        boolean bYear      = false;
        boolean bGenre     = false;

        public void startElement(String uri, String localName, String qName, Attributes attr)
                throws SAXException {
            if (qName.equalsIgnoreCase("ARTIST"))    { bArtist = true; }
            if (qName.equalsIgnoreCase("ALBUMNAME")) { bAlbumName = true; }
            if (qName.equalsIgnoreCase("YEAR"))      { bYear = true; }
            if (qName.equalsIgnoreCase("GENRE"))     { bGenre = true; }
        }
        public void characters(char ch[], int start, int length) {
            if (bArtist) {
                outputString.concat("Artist: " + new String(ch,start,length) + "\n");
            }
            if(bAlbumName) {
                outputString.concat("Album: " + new String(ch,start,length) + "\n");
            }
            if(bYear) {
                outputString.concat("Year: " + new String(ch,start,length) + "\n");
            }
            if(bGenre) {
                outputString.concat("Genre: " + new String(ch,start,length) + "\n");
            }
            outputString.concat("\n");
        }
    };

    saxParser.parse(readFile,handler);
    return outputString;
}

It should be org.xml.sax.helpers.DefaultHandler not jdk.internal...

so

import org.xml.sax.helpers.DefaultHandler;

You should probably also define the class that extends the DefaultHandler not just inline it.
