missing bracket

Does anyone know why i might be getting an '}'
expected error at line 60 which is basically
at the end of the program? I dont see that
i am mising any brackets.

Im doing a little program that was
assigned by one of my friends teachers
as a project. So i decided to do
it to just to get some practice. My algorithm
for calculating the string is off {just to tell you}
so ill have to work on it. :D

Code:

---

// create a method that takes a String as an arguement and returns a TreeMap
// which will map the string and the number of characters that occur only
// once within the string. since the counting operation can be
// time consuming, the method should cache 
// the results so that when the method is
// given a string previously encountered,it will
// simply retrieve the stored result.
   
  import java.io.*;
  import java.util.*; 
 
  public class MultipleChar{
    public static void main(String[] args){

    for(;;){
      BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
        try{
        System.out.println("Please enter a string");
        String key = buff.readLine();
        TreeMap tm = (TreeMap) checkForDuplicates(key);
     
        System.out.println("Within" + tm.get(key) + "there were" +  "characters that only appeared once");
        System.out.println("Press x if you would like to exit");
        String exit = buff.readLine();
        if(exit.equalsIgnoreCase("x")){System.exit(0);}
      }catch(Exception e){System.err.println(e);}
    } // end for
    } // end main
 
  public static Object checkForDuplicates(String key){
        int onlyappearsonce = 0;
        boolean charmatch = false;
        String matchingString;
        Map stringMap = new TreeMap();
       
   
    // check map to see if string is present
    // if it is return key
 
        for(Iterator i = (stringMap.values()).iterator();  i.hasNext();){           
          if(stringMap.containsKey(key)){
            return stringMap.get(i.next());   
            }
          i.next();
        }
    // if string is not present
  // calculate characters that only appear once and add to map
     
    for(int index = 0; index <= matchingString.length() - 1; ++index){
          char matchingchar = matchingString.charAt(index);
                     
          for(int x = 1 + index; x <= matchingString.length() - x ; ++x){
              if(matchingchar == matchingString.charAt(x)){
                  charmatch = true;
                  break; 
          }
          if(charmatch == false){++onlyappearsonce;}   
    }
    Integer charcount = new Integer(onlyappearsonce);
    return stringMap.put(key,charcount);
  }

Code:

---

if(matchingchar == matchingString.charAt(x)){
                  charmatch = true;
                  break;

I think it is here. You do't appear to have closed off your If block

:)

also add another } to close off the class block

;)

Your right.... I fixed it but i still keep getting '}' expected at line
63. very weird.

Duh? Im an idiot. I forgot to add a } for the class block. Thanks for pointing that out. It would have drove me crazy. :D
