Filling a 2D array with characters using data input from file - Java

I am trying to fill an array of chars using data input from file, while parsing the file I am also trying to store some values, but things are not working.

This is my code:

char[][] board = new char[ROWS][COLS];          

        for( int row = 0; row < board.length; row++){
            for (int col = 0; col < board[row].length ; col++){
                if (fileScan.hasNext()){
                    board[row][col]= fileScan.next().charAt(0);
                    if(board[row][col] == START){
                        startingPoint = new Point(row, col);
                    }                   
                    if(board[row][col] == END){
                        endingPoint = new Point(row, col);
                    }
                }

}

Given that then input file has

1 O O 
O O O 
O X 2 

this is what i get when I run it:

 O O 
 O X 

java.lang.NullPointerException
