Terminating input with a full stop ' . '

Question

Hi
I am writng some code that enables input to be broken into strings using a StringTokenizer then stores the strings in the vector. I am only interested in the first sentence and therefore want to terminate input immediately prior to the pint where a user enters a full stop '.' (if they enter a full stop)
This is the code so far,
public static void main (String [] args ) throws IOException {
     BufferedReader keyBoard = new BufferedReader( // creates a BufferedReader to store input                                                  
     new InputStreamReader (System.in)); // sets up streams
     String sentenceForward;
     System.out.println ("Please enter a sentence"); // prompts the user to enter a sentence
     System.out.println("");
     sentenceForward = keyBoard.readLine(); // reads the sentence inputted and stores it in a variable
     StringTokenizer st = new StringTokenizer (sentenceForward); // Breaks the sentence into tokens
     Vector v = new Vector (); // Constructs an empty vector
     String w;
     while (st.hasMoreTokens()) {
          w = st.nextToken();
          v.add(w.toLowerCase()); // creates a vector containing the user input
                                        // converted to lower case
     } // end while
Any help would be appreciated...
Thanks

Break off the first sentence first...
sentenceForward = keyBoard.readLine(); // reads the sentence inputted and stores it in a variable
sentenceForward = sentenceForward.substring(0, sentenceForward.indexOf('.')+1); // only keep up to and including first .
StringTokenizer st = new StringTokenizer (sentenceForward); // Breaks the sentence into tokens
