How do I call a function in java?

Question

I'm calling a function called lightParse() from the method. But, I'm getting an error:
F:\Data>javac -classpath xerces.jar;xalan.jar;classpath%; Test.java
Test.java:22: lightParse(java.lang.String) in Test cannot be applied to ()
lightParse();
^
The scenario or code portion is :
import javax.swing.*;
import java.awt.*;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
public class Test extends JFrame
     JList list;
     JScrollPane listContainer;
     public Test()
          setSize(300, 300);
          setVisible(true);
          initialize();
          lightParse(); // calling the function
     public void initialize()
          list = new JList(new DefaultListModel()); // Set the initial model
          listContainer = new JScrollPane(list);
          listContainer.setSize(new Dimension(200, 200));
          getContentPane().setLayout(new BorderLayout());
          getContentPane().add(listContainer, "Center");
          validate(); // Validate the screen
// The function is the following
     public void lightParse(String url)
          DocumentBuilder parser;
          DocumentBuilderFactory factory =
                    DocumentBuilderFactory.newInstance();
          try {
                    parser = factory.newDocumentBuilder();
                    Document doc = parser.parse(url);
How do I call the function correctly with the right parameter?
Thanks in advance for the answer.

Answer 1

u r calling lightParse method without passing the expected "String" argument. There must not be an overloaded method for lightParse without any arguments.
So u should use this:
lightParse(some string here);
Hope this explains.
