Please help me on this question in Java, other answer on chegg doesn't work. Thank you so much
Question:
Create a simple game of mine sweeper with the following classes and a driver
Download the driver
Put the driver in your project
DO NOT ALTER THE DRIVER!
Write a class file called MineSpace
Attributes of this class
Selected – determines whether or not this space has been clicked on
IsAMine – this is whether or not it is a mine
SurroundingMines – The number of mines surrounding that space
Create a default constructor with the following
Selected is set to false
IsAMine is randomly set to either true or false
Create Accessors and Mutators for each instance variable
MAKE SURE TO CHECK FOR VALID VALUES
Write another class SimpleMineSweeperBackEnd
Attributes of this class are
Spaces – a 2D array of type mine space
SPACE_AMT – a constant value set to 5 as this is a 5x5 minefield
numNotMinesLeft – the number of mines left on the board
gameOver – whether or not the game is over
win – whether or not the player wins
Create a default constructor
Declare the 2D array
Call reset spaces
Create the following Methods
resetSpaces – this method returns nothing and takes no parameters constructs each individual space and counts the number of not mines. It also sets each mine surroundingMines value by looking at each of its neighbors (HINT: looking setting the number of mines value maybe best done in a private method). Also it sets both gameOver and win to false.
getNumNotMinesLeft – returns how many spaces that aren’t mines remain
getGameOver – returns whether or not the game is over
getWin – returns whether or not the player has won
printMines – prints each mine space in the 2D array. It should print whether or not it is a mine and the number of surrounding mines. This is really good for debugging.
selectSpace – this method which returns an instance of Space takes in two integers corresponding to the button that was selected. Much like other projects the x increase left to right and the y increases from top to bottom. This method should check if it is already select. If it hasn’t been then set selected to true. Next check if that space is a mine. If it is then set gameOver to true and win to false. If not then subtract the number of not mines left. Next check if the number of not mines is 0 then game over should be set to true and win should be set to true.
