Cast int to char

[Chasingxsuns]

    public void updateGrid(ListStack<Position> stack) {
        LinearNode<Position> trav = stack.getTop();
        int count = stack.size();
        //go through stack, apply position numbers to the grid
        while(trav.getNext() != null) {
            char val = (char) (count);
            System.out.println(val);

            grid.getMap()[trav.getElement().getX()][trav.getElement().getY()] = val;
            trav = trav.getNext();
            count--;
        }   //end while
    }

Instead of printing a character value of count, all it prints is a blank line (or maybe ' '). I don't get why. Is that not the correct syntax for casting an int to a char??

Your code does this...

// Get the length of this list and store it in count
// Convert the number count to a character and store in val
// Print the character stored in val

Are you sure this is what you want to accomplish?
Because lower character values are weird, some are just blanks.

For example:

class Test {
  public static void main(String[] args) {
    for (int i=0; i<92; i++) {
	    char c = (char) i;
	    System.out.println( i+ "[" +c+ "]" );
    }
  }
}

(I don't see the goal of your code.)
