Okay so im trying to load a .txt to an array so it can be set a tiles. However on the loading im getting a "NullPointerException". Can someone point me into the right direction to where im going wrong? Possiably some source code please !

	private static final long serialVersionUID = 1L;
    public static Image GRASS;
    public static Image DIRT;
    
    private int x, y;
	private static int xDirection;
	private static int yDirection;
	
	static Rectangle[] blocks;
    static Image[] blockImg;
	
	private final int arrayNum = 523;
	
    //Map navigation
    public static final int PAN_UP = 0, PAN_DOWN = 1, PAN_LEFT = 2, PAN_RIGHT = 3;
    
    public WorldMap() {
       
        ImageIcon g = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/Map/grass.png");
        ImageIcon d = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/Map/dirt.png");

        GRASS = g.getImage();
        DIRT = d.getImage();
        
        setSize(501, 419);
        
        blocks = new Rectangle[523];
        blockImg = new Image[523];
        
        loadMap();
       
    }

	public void loadMap() {

        int x = 0;
        int y = 0;
        int j = 0;
        int loc = 0;
  
        try {
            File file = new File(System.getProperty("user.home") + "/Desktop/GAME/Map/map.txt");
            Scanner scan = new Scanner(file);
            for (String line = scan.nextLine(); line != null; line = scan.nextLine()) {
                j = line.length() * 20;
                while (j > x) {
                	for(int i = 0; i < arrayNum; i++){
                		char c = line.charAt(loc);
                		if (c=='G') {
                			blockImg[i] = GRASS;
                			blocks[i] =  new Rectangle(x, y, 20, 20);
                		}
                		if (c=='D') {
                			blockImg[i] = DIRT;
                			blocks[i] =  new Rectangle(x, y, 20, 20);
                		}
                		x += 20;
                		loc++;
                	}
                }
                y += 20;
                x = 0;
                loc = 0;
             }
        } catch (Exception e) {  
        }
    }
