Reading in spaces as well as characters with the Scanner

Hello I want to be able to read in mazes from a properly formatted text file with the size of the maze by row and colum at the top followed by the maze using asterisk(*) for walls and a space for pathway. The entry would look something like this:
9 20
********************
* * *
** ** ***** ** *****
* * * * * *
* * * * * * *
* * * *
************* ** *
*
********************
I can't seem to figure this out even when setting the delimiter to nothing(""). I can get it to work with sapces between each asterisks and dashes instead of spaces for paths, which looks like this:
9 20
* * * * * * * * * * * * * * * * * * * *
* - - - - - - * - - - - - - - - - - - *
* * - * * - * * * * * - * * - * * * * *
* - * - * - - - - - * - * - - - - - - *
* - - - * - - - - - * - - - * - * - * *
* - - - - - * - - - - - - - - - - * - *
* * * * * * * * * * * * * - - * * - - *
* - - - - - - - - - - - - - - - - - - G
* * * * * * * * * * * * * * * * * * * *
Note: The G represents the goal.
Here is the code that I've been trying to get to work for the first one:

	//My method to populate and create the maze.
	private static String[][] populateMaze() {
		JFileChooser fchoose = new JFileChooser();//This finds a text file via JFileChooser
		int returnVal = fchoose.showOpenDialog(null);
		if(returnVal == JFileChooser.APPROVE_OPTION)
			//Try catch in order to open the file, scan it, 
			//and then populate my String array with it
			try {
				//Creating a scanner attached to the selected file.
				Scanner in = new Scanner(fchoose.getSelectedFile());
				//Using the first two ints in the .txt to create my Array
				String[][] maze = new String[in.nextInt()][in.nextInt()];
				in.useDelimiter("");//Setting my delemiter to nothing.
				for(int row = 0; row < maze.length; row++){//Nested for's to populate the maze
					for(int col = 0; col < maze[0].length; col++){
						maze[row][col] = in.next();//Getting the next thing in the file
					}
				}
				return maze;//Returns the completed maze
			//Catching errors	
			} catch (FileNotFoundException e1) {
			} catch (IOException e1) {
			}
		//fallback to deal with the compiler
		String[][] fallBack = new String[9][20];
		return fallBack;
		}

Anyone have any ideas or advice to give me to get this thing to work? I've been pulling my hair out to figure it out.
