java-minesweeper (complete the code)

The model (20 marks)

The first step is to build the model of the game. This will be done via the class GameModel and the helper class DotInfo. Our unique instance of the class GameModel will have to store the current state of the game. This includes

The icon (number of neighbouring mines, or blank if none) and status (covered or not) of each dot on the board. The class DotInfo helps with this.

The size of the board. The number of steps taken by the player so far

The number of mines around each dots

The total number of mines in the Model

The number of uncovered dots so far

It also provides the necessary setters and getters, so the the controller and the view can check the status of any square, and the controller can change the status of a square. Finally, it provides a way to (re)initialize the game, reallocating the initial position of the mine randomly. A detailed description of the classes can be found in the documentation.
