I have written the code below, but now i am compleatly stuck!! i need to change this code to read in a name from the user then search the treemap for that name and return that name.
The names are stored in a txt file like:
john anderson:0123456322
jim collet:0176849323
Is it possible to put these names and number in the tree map, and have name as a key and number as a value, then search the treemap?? pls help!!

class Treemap {  
  public static void main(String[] args) {     
    Map phoneBook = new TreeMap();    
    BufferedReader in = new BufferedReader(new FileReader("directory.txt"));    
    String line;     
    while ((line = in.readLine()) != null) {        
      String line = in.readLine();             
      int pos = line.indexOf (":");      //So use String.substring to get the parts of the line.           
      String name = line.substring (0, pos);            
      String number = line.substring (pos + 1);
      phoneBook.put (name, number);
[ArchAngel adjusted text in CODE tags so that it's not all on one line]
