Find start/end of word contained in text.

Question

I feel really silly asking this, but my brain doesn't seem to want to work at the moment and I can't find my old semester 1 examples.
While I can easily solve this in C++ trying to do it in Java is a bit of a mystery. size_t = found, str.find() string::npos -> etc
Basically I'm trying to implement a default highlighter. The words I need to search for AFAIK only appear once each in the Document or not at all.
SQL queries, SELECT, FROM, WHERE, etc.
I'm going off an example I found here: [http://www.java2s.com/Code/Java/Swing-JFC/Anexampleofhighlightingmultiplediscontiguousregionsofatextcomponent.htm]
Which searches for vowels within a document and highlights. So i figured it would be an easy switch to get it to do what I wanted, but I've been plugging away at it for a few hours now and can't solve it.
Would be a lot easier if String.contains(CharSequence cs) gave something back more useful than a boolean... integer would be nice :(
Anyway sample is below, to make it simple I have a simple query in the text pane, and only search for the 3 words, select from where.
Can anyone tell me how I would go about telling the addHighlight() method of the word found?
import java.awt.BorderLayout;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
public class MultiHighlight implements ActionListener
     private JTextComponent comp;
     private String[] wordsToHighlight;
     public MultiHighlight(JTextComponent c, String[] words)
          comp = c;
          wordsToHighlight = words;
     public void actionPerformed(ActionEvent e)
          // highlight
          Highlighter h = comp.getHighlighter();
          h.removeAllHighlights();
          String text = comp.getText().toUpperCase();
          for (int i=0;i<wordsToHighlight.length;i++)
               if (text.contains(wordsToHighlight))
                    // find start, find end... ?
                    h.addHighlight(start, end, DefaultHighlighter.DefaultPainter)
     public static void main(String args[])
          JFrame frame = new JFrame("MultiHighlight");
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JTextArea area = new JTextArea(5, 20);
          area.setText("Select *\nFrom stuff s, more m\nWhere s.otherstuff = m.otherstuff.");
          frame.getContentPane().add(new JScrollPane(area), BorderLayout.CENTER);
          JButton b = new JButton("Highlight All SQL words");
          String[] wordsToLookFor = { "SELECT", "FROM", "WHERE" };
          b.addActionListener(new MultiHighlight(area, wordsToLookFor));
          frame.getContentPane().add(b, BorderLayout.SOUTH);
          frame.pack();
          frame.setVisible(true);

Answer 1

int start = text.indexOf(wordsToHighlight);
                    int end = start + wordsToHighlight[i].length();
                    try {
                         h.addHighlight(start, end, DefaultHighlighter.DefaultPainter);
                    } catch (BadLocationException e1) {
                         e1.printStackTrace();
