The Game class

An instance of the Game class contains a Row holding the secret color values and also contains a Table. When there is a new guess the Game instance stores the guess into the Table and also sets the number of positions and colors matching the secret row.

     final private Row secretRow; 
     boolean finished = false;

         this.table = table; 
         this.secretRow = new Row(secret); 
     } 
  
     public void addNewGuess(Row row) { 
         if( isFinished()){ 
             throw new IllegalArgumentException( 
                        "You can not guess on a finished game."); 
         } 
         final int positionMatch = secretRow. 
                           nrMatchingPositions(row.positions); 
         final int colorMatch = secretRow. 
                           nrMatchingColors(row.positions);
