Iterating over strange object

Question

this must be pretty simple but i can't figure out what to do:
I have a class defined like this:
public IndexExample  (String infile){
          Map<String,TreeSet> IndexExample = new TreeMap<String,TreeSet>();
.IndexExample is not empty now i want to run over the Map, and for each string run on the TreeSet, I though about something like this:
however the bolded stuff gives me:
"The method entrySet() is undefined for the type IndexExample"
what should i do?
[u]Set s = this.entrySet();[/u]
          Iterator iter1 = s.iterator();
        while (iter1.hasNext()){
            Map.Entry m = (Map.Entry)iter1.next();
            String key = (String)m.getKey();
            TreeSet pages = (TreeSet)m.getValue();
            Iterator iter2 = pages.iterator();
             }thanks

Answer 1

thank you all
but what i didn't mention (oopse)
that the first piece of code is the constructor for the class.
the second piece of code is some method.
but it doesn't let me use the method entrySet();
thanks in advance...
i put my code again:
import java.io.*;
import java.util.*;
public class IndexExample{
     final static char DELIMITER = ';';
//constructor:
     public IndexExample  (String infile){
          Map<String,TreeSet> IndexExample = new TreeMap<String,TreeSet>();
           try {
                BufferedReader in = new BufferedReader(new FileReader(infile));
                 String line;
                 while ((line = in.readLine()) != null) {
                     int delimiterIndex = line.indexOf(DELIMITER);
                     if (delimiterIndex < 0) {
                          continue;
                     String argument1 = line.substring(0,delimiterIndex-1);
                     String argument2 = line.substring(delimiterIndex+1,line.length());
                     String key = (argument1).trim();
                     Integer pageNumber = new Integer(argument2.trim());
                     TreeSet<Integer> pages = new TreeSet();
                     if (IndexExample.containsKey(key)) {
                          pages = IndexExample.get(key);
                     else {
                          pages = new TreeSet();
                     pages.add(pageNumber);
                     IndexExample.put(key,pages);
                 in.close();
             catch (IOException e) {
//some method
     public void toFile(String outFile){
          PrintWriter out = new PrintWriter(new FileWriter(outFile));
          Set s = this.entrySet();
          Iterator iter1 = s.iterator();
        while (iter1.hasNext()){
             Map.Entry m = (Map.Entry)iter1.next();
            String key = (String)m.getKey();
            TreeSet pages = (TreeSet)m.getValue();
            Iterator iter2 = pages.iterator();
            out.print(key + ", ");
             while (iter2.hasNext()){
                  int i = (Integer)iter2.next();
                  out.print(i + " ");
             out.println("");
        out.close();
        }
