While 0's represent wall/obstacles, 1's represent a path. One can define another class for MazeCellType where type can be a path and a wall

private void CreateDungeon() {
        BufferedReader reader = null;
        try {
            reader = new BufferedReader(new FileReader(Constants.dungeonFile));
            String line;
            int lineNumber = 0;
            while ((line = reader.readLine()) != null && !line.isEmpty()
                    && lineNumber < this.sizeOfMaze) {
                int columnNumber = 0;
                String[] paths = line.split("0");
                for (int i = 0; i < paths.length; i++) {
                    String path = paths[i];
                    int j = 0;
                    while (j < path.length() && columnNumber < this.sizeOfMaze) {
                        this.dungeon[lineNumber][columnNumber].type = Path;
                        columnNumber++;
                        j++;
                    }
                    if (columnNumber < this.sizeOfMaze) {
                        this.dungeon[lineNumber][columnNumber].type = Wall;
                        columnNumber++;
                    }
                }
                lineNumber++;
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (Exception e) {
                    //eat it
                }
            }
        }
    }

If somebody can tell what all possibilities exist for maze.

class Cell
{
public:
       int x;
       int y;
       bool left, right, up, down; // whether it can go left/right/up/down
};

class Maze
{
    std::list<Cell> cells;
};
