QUESTION TO BE ANSWERED:
Your assignment is to complete the implementation of the Mine Sweeper game. To do so, you will need to write a class in thecs2114.minesweeperpackage calledMineSweeperBoard, and make it extend theMineSweeperBoardBaseabstract base class. You will have to implement all of the abstract methods required by the base class. In addition,you may need to design and implement your own helper methods to keep your code clean and easy to understand.Think carefully about the internal design of your class. Glance over the project that you were given. The "src" folder is where you will do all your work.
(To create the class in the correct package, expand the "src" folder and then right-click on cs2114.minesweeper and choose "New > Class" from the menu.)
You do not need to implement the non-abstract methods in MineSweeperBoardBase, namely equals, toString, and loadBoardState. These are already implemented for you to support testing and debugging, so don't waste valuable time reinventing the wheel.
The MineSweeperBoard class is responsible for keeping track of the contents of the Mine Sweeper board as the game is being played. Many of the details you will need to perform this implementation can be found in the Java Documentation for the MineSweeperBoardBase class. The following sections contain some additional information about the MineSweeperBoardBase class and give an outline for how to approach this assignment.
In addition to the abstract methods that you must implement, you must also provide a MineSweeperBoard constructor that takes three arguments: the width of the board, the height of the board, and the number of mines to place on the board, in that order. In addition to creating the space to store the cells, your constructor should randomly place the specified number of mines on the board.
To randomly place mines, you can use the java.util.Random class .
Representing the Board
In this assignment, each cell on the game board is represented by an enumerated type named MineSweeperCell. As a quick review, an enumerated type (or enum for short), is a type that represents a small fixed set of choices that you can refer to by name. So, for example, MineSweeperCell.COVERED_CELL would represent a cell on the board that is covered; we'll discuss the types in more detail below.
We will use a two-dimensional array of MineSweeperCell values to represent the current state of the playing board inside your MineSweeperBoard class. In fact, you are required to use a two-dimensional array in your representation to ensure you get more practice with this low-level feature (you may not use ArrayLists or other java.util structures to store the board grid in this assignment).
When you model the board state as a two-dimensional array of MineSweeperCell values, the value contained in each cell indicates the contents of the cell and whether or not it has been uncovered or has had a flag placed on it. The following table gives a list of the values that may appear in such an array:
MineSweeperCell.COVERED_CELL
An array entry containing the value COVERED_CELL indicates an empty cell on the board that has not yet been uncovered by the player.
MineSweeperCell.MINE
An array entry containing the value MINE indicates a cell containing a mine which has neither been uncovered by the player nor has it had a flag placed on it.
MineSweeperCell.FLAG
An array entry containing the value FLAG indicates a cell that does not contain a mine, but which has had a flag (incorrectly) placed on it.
MineSweeperCell.FLAGGED_MINE
An array entry containing the value FLAGGED_MINE indicates a cell that does contain a mine and has had a flag (correctly) placed on it.
MineSweeperCell.UNCOVERED_MINE
An array entry containing the value UNCOVERED_MINE indicates a cell containing a mine which has been uncovered by the player.
MineSweeperCell.ADJACENT_TO_0...MineSweeperCell.ADJACENT_TO_8
An array entry containing one of these values indicates an empty cell which has been uncovered. The specific value between 0 and 8 indicates the number of mines which appear in the adjacent cells.
The MineSweeperCell enumerated type also has a helper method named adjacentTo that takes an integer between 0 and 8 and returns the appropriate enum value. For example, MineSweeperCell.adjacentTo(4) returns MineSweeperCell.ADJACENT_TO_4. You should use this helper method where appropriate to avoid complex if/switch logic when you need to convert a number of adjacent mines into the matching enum value.
To help clarify the meaning of these values consider the following examples. When a new MineSweeperBoard is created it will contain only COVERED_CELLs and MINEs. The MINEs will be placed randomly in the array. For example if the new array has width 4 and height 3 it might look as follows:
If the player were to left click on the upper right hand cell of the board then the MineSweeperBoard class would change cell (0,3) of its array to ADJACENT_TO_0 as shown below:
Cell (0,3) was changed to ADJACENT_TO_0 reflecting the fact that the cell has been uncovered and that there are no mines adjacent to this cell. When the Mine Sweeper game sees ADJACENT_TO_0 in this location it will display a sunken blank icon in the upper-right corner.
If the player were now to click in the center cell in the left-most column, the MineSweeperBoard would change cell (1,0) in its array to ADJACENT_TO_2, indicating that there are two mines adjacent to that cell. When the Mine Sweeper game see ADJACENT_TO_2 in this location it will display a sunken icon containing the number 2. The array would now appear as follows:
If the player were now to right click on the cell in the lower-left corner of the board to place a flag on that cell, the MineSweeperBoard would change cell (2,0) of its array to FLAG. Recall that the value FLAG indicates that a flag has been (incorrectly) placed on a cell which does not contain a mine. The array would now appear as shown below:
If the player now right clicks on the cell in the upper-left corner of the board, the MineSweeperBoard would change cell (0,0) of its array to a FLAGGED_MINE. The value FLAGGED_MINE indicates that a flag has been (correctly) placed on a cell containing a mine. The array would now appear as shown below:
Imagine now that player, having decided that the cell in the lower-left corner of the board should not be flagged, right-clicks again on the lower-left corner cell. The MineSweeperBoard must now change cell (2,0) of its array back to an UNCOVERED_CELL. Similarly, if the player were to decide to remove the flag from the upper-left corner, the MineSweeperBoard class would have to change cell (0,0) of its array back to a MINE. Finally, if after removing the flag from the upper-left corner of the board, the poor unsuspecting player left clicks that cell, the MineSweeperBoard will change cell (0,0) to a UNCOVERED_MINE, effectively causing the game to end.
To Do
Take time to understand the methods provided by the MineSweeperBoardBase abstract class. You don't have the code for this class, but you have the JavaDoc documentation. Your job is to write your own MineSweeperBoard class that extends MineSweeperBoardBase and implements all of the methods it declares and capitalizes on the design aspects already in place.
In addition, you will also need to test your work. Don't save testing until the end - instead start writing tests for each piece of behavior as you add it in order to get the most benefit.
When you are done, you will have an almost complete, working Mine Sweeper game!
Testing Tips
For this project you are responsible for testing the MineSweeperBoard class. The testing can be based on a simple test fixture - perhaps a 4x4 board with explicit characteristics.
Note that the base class provides the loadBoardState() method, which you can use to set up specific testing situations. The toString() method can be used to print the current state of the board to the terminal window:
Here is a sample test case for the setCell() method:
This example uses a helper function called assertBoard() as a useful building block for simplifying test cases. You can use it as a model in your own code (with some care in your design, you can simplify it even further!). Note that it uses a variable number of arguments, taking a board followed by any number of strings. The entire group of arguments representing the variable part of the method's signature are accessible inside the method's body as a raw array.
Most of your testing will use loadBoardState(), which means any mine placement in your constructor won't affect your tests. However, to write a test case that exercises your random mine placement, read the page on Testing Tips for Random Numbers.
Notes
The uncoverCell() method should only change the single cell specified. It is not necessary to attempt to replicate the behavior of the Windows version of mine sweeper where uncovering an empty cell causes a cascaded "auto-uncovering" of all adjacent empty cells as well. Instead, only uncover the one cell specified, which makes the assignment easier for everyone.
Running Your Tests
To run your tests, right-click "Assignment01-Minesweeper" in your workspace and choose "Run As > JUnit Test" from the menu. When they're done, the JUnit view will automatically be brought to the front and show your test results.
