How to add to java classpath?

Question

I am wondering how to add/implement to java classpath. I think I might be missed out the classpath thing so my program doesn't work. I keep getting error message like: "cannot resolve symbol: method setDocumentHandler(BookCounter)" and warning messages like: "C:\Example\BookCounter.java :11: warning:org.xml.sax.HandlerBase in org.xml.sax has been deprecated." and "C:\Example\BookCounter.java :16: warning:org.xml.sax.HandlerBase in org.xml.sax has been deprecated."
If this is not because of classpath problem, kindly let me know what should I do?
My code as follow:-
========================
import java.io.*;
import org.xml.sax.*;
import org.xml.sax.HandlerBase;
import javax.xml.parsers.SAXParserFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
public class BookCounter extends HandlerBase
private int count = 0;
public static void main (String args[]) throws Exception
(new BookCounter()).countBooks();
public void countBooks() throws Exception
SAXParserFactory f = SAXParserFactory.newInstance();
SAXParser f2 = f.newSAXParser();
// Parser p = new com.jclark.xml.sax.Driver();
f2.setDocumentHandler(this);
f2.parse("file:///C:/books.xml");
public void startElement(String name) throws SAXException
if (name.equals("book"))
count++;
public void endDocument() throws SAXException
System.out.printIn("There are" + count + "books");

Answer 1

The errors don't look like classpath problems. The first one is a result of it not being able to find a method in BookCounter (or more likely HandlerBase) that has the signature that you are attempting to use.
The warnings come from the fact that HandlerBase has been deprecated, just like the messages state. In other words, it has been replaced by a newer version, or incorporated into another class' functionality. Check the API for more information.
