This is what i have written so far but when exception is raised it does not again ask teh user for input.

do{

System.out.println("Enter the number of stones to play with: ");

    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));  

     String temp=br.readLine();

    }while (key<0 && key>9);


          if(key<0 || key>10)
        throw new InvalidStartingStonesException(key);

                 player1=new KeyBoardPlayer();
         player2 = new KeyBoardPlayer(); 
         this.player1=player1;
         this.player2=player2;
         state=new KalaGameState(key);


    }
     catch(NumberFormatException nFE) {
             System.out.println("Not an Integer");}
    catch(IOException  e)
{
            System.out.println(e);
        }
