Mình có bài tập về java, The Allotment Game, trò chơi luân phiên theo tiếng anh như sau:

The Allotment Game involves two stages. During the first stage a player plants some vegetables in small plot of land that is divided into a grid of 8x8 cells. The second stage involves a second player guessing where those vegetables were planted. 10 vegetables must be planted in total, comprising one turnip, two carrots, three potatoes and four radishes. No vegetable is allowed to touch any other, including along diagonal cells. A turnip must consist of four adjacent cells in a square; a carrot three adjacent cells in a straight line; a potato two adjacent cells and a radish a single cell. An example of a valid layout of vegetables is shown to the left.

The second phase of the game involves a second player trying to deduce the location of all the vegetables. They are initially presented with a blank grid representing the plot with the buried vegetables. The only clue is that the number of cells occupied by all or part of a vegetable in each row and column is shown. An example can be seen to the left (note that this is just an example - in the real game, the row and column totals are likely to be different although they always sum to 20).

The player has to choose a cell to dig - each cell is referenced by a row and column number, so the top left cell is [1,1], the bottom-left [8,1] etc. When a cell is dug, its content is revealed, which can be either the name of a vegetable (e.g. at cell [3,5] the contents would be revealed as a 'P' in the example shown), or as 'empty' (e.g. at cell [5,6]). Using the row and column totals and the known rules about vegetable placement, the idea is to find all the vegetables with the minimum amount of digging. For every cell dug that is empty, the player receives one penalty point. The total can therefore vary between 0 (perfect identification of all vegetables) and 44 (all empty cells were dug before finding all the veggies).

Your task is to create classes and Java code to do the following:

Allow the state of the allotment to be stored (grid of 64 cells with the 10 vegetables arranged within it).

Allow the 10 vegetables to be placed in the allotment using keyboard input.

Check that the locations of all the vegetables conform to the rules of the game (e.g. not touching, turnips comprising a square of 4 cells etc.)

Create output showing the state of the allotment using text (e.g. using System.out.println()). No windows-based GUI is required.

In designing your classes you should think about how they might in the future be extended to allow the digging part of the game to proceed. However, you are not required to code that part of the game.

mình đã mò ra được hướng thiết kế đối tượng như sau:

carrots, turnip, radishes và potatoes là class con của class "Vegetable",

Tuy nhiên mình bị bí lù ở chỗ, class "Grid", nơi chứa 64 ô trồng, thuật toán như thế nào để tạo 64 ô như sau:

Ngoài ra còn thuật toán kiểm tra các rau củ không bị chạm vào khi gieo trồng....

Mong các bạn giúp đỡ
