Creating a Simple MineSweeper Game with Java Code

The classic game of MineSweeper has been a popular puzzle game for many years, challenging players to uncover hidden mines by clicking on safe squares. In this article, we will explore how to create a simple version of the game using Java code.

To begin, let's take a look at the basics of the game. The MineSweeper game is represented as a 2D array, where each cell contains an integer from the range 0-9, representing the number of mines in itself and all the eight cells adjacent to it. The task is to solve the minesweeper by uncovering all the mines in the matrix.

Here's a simple implementation of the game using Java code:

```java

import javax.swing.*;

import java.awt.*;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

public class Minefield extends JPanel {

private boolean'''' mineField;

private JButton'''' buttons;

private int rows, columns, numMines;

public Minefield(int rows, int columns, int numMines) {

this.rows = rows;

this.columns = columns;

this.numMines = numMines;

mineField = new boolean'rows''columns';

buttons = new JButton'rows''columns';

for (int i = 0; i < rows; i++) {

for (int j = 0; j < columns; j++) {

buttons'i''j' = new JButton((i + 1) + ', ' + (j + 1));

add(buttons'i''j');

buttons'i''j'.addActionListener(new MouseHandler());

}

// Assign mines randomly

for (int i = 0; i < numMines; i++) {

int row = (int) (Math.random() * rows);

int column = (int) (Math.random() * columns);

mineField'row''column' = true;

}

private class MouseHandler extends MouseAdapter {

public void mouseClicked(MouseEvent e) {

JButton button = (JButton) e.getComponent();

String buttonText = button.getText();

// Get the row and column of the button

int row = Integer.parseInt(buttonText.split(', ')'0') - 1;

int column = Integer.parseInt(buttonText.split(', ')'1') - 1;

if (mineField'row''column') {

// If the cell contains a mine, change the button text to 'M'

button.setText('M');

} else {

// Count the number of mines adjacent to the current cell

int count = 0;

for (int i = -1; i <= 1; i++) {

for (int j = -1; j <= 1; j++) {

if ((row + i >= 0) && (row + i < rows) &&

(column + j >= 0) && (column + j < columns) &&

mineField'row + i''column + j') {

count++;

}

// Change the button text to the number of mines

if (count > 0) {

button.setText(String.valueOf(count));

} else {

// If there are no mines adjacent, change the button text to 'T'

button.setText('T');

}

public static void main(String'' args) {

int rows = 20;

int columns = 20;

int numMines = 30;

Minefield minefield = new Minefield(rows, columns, numMines);

JFrame frame = new JFrame('MineSweeper');

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.add(minefield);

frame.pack();

frame.setVisible(true);

}

```

In this code, we create a 2D array `mineField` to represent the minesweeper matrix. We also create an array of `JButton`s to represent each cell in the matrix.

The `MouseHandler` class is responsible for handling mouse clicks on the buttons. When a button is clicked, it checks if the corresponding cell contains a mine. If it does, it changes the button text to 'M'. If not, it counts the number of mines adjacent to the current cell and changes the button text accordingly.

The `main` method creates an instance of the `Minefield` class with a 20x20 grid and 30 mines, and displays it in a JFrame.

This is a very basic implementation of the game, and there are many ways to improve it. For example, you could add more features such as flagging cells or displaying the number of mines remaining.
