java图形化界面五子棋

以下是Java图形化界面五子棋的实现方法：

1. 创建一个棋盘类，用于绘制棋盘和处理子事件。

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class ChessBoard extends JPanel implements MouseListener {
    private static final int ROWS = 15;
    private static final int COLS = 15;
    private static final int CELL_SIZE = 30;
    private static final int MARGIN = 30;
    private static final int GRID_SIZE = CELL_SIZE * (ROWS - 1) + MARGIN * 2;
    private static final int PIECE_SIZE = (int) (CELL_SIZE * 0.8);
    private static final int PIECE_OFFSET = (CELL_SIZE - PIECE_SIZE) / 2;
    private static final int[][] POSITIONS = new int[ROWS][COLS];
    private static final int EMPTY = 0;
    private static final int BLACK = 1;
    private static final int WHITE = 2;
    private int currentPlayer = BLACK;
    private boolean gameOver = false;

    public ChessBoard() {
        setPreferredSize(new Dimension(GRID_SIZE, GRID_SIZE));
        setBackground(Color.ORANGE);
        addMouseListener(this);
    }

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        for (int i = 0; i < ROWS; i++) {
            g.drawLine(MARGIN, MARGIN + i * CELL_SIZE, MARGIN + (COLS - 1) * CELL_SIZE, MARGIN + i * CELL_SIZE);
            g.drawLine(MARGIN + i * CELL_SIZE, MARGIN, MARGIN + i * CELL_SIZE, MARGIN + (ROWS - 1) * CELL_SIZE);
        }
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                if (POSITIONS[i][j] == BLACK) {
                    g.setColor(Color.BLACK);
                    g.fillOval(MARGIN + j * CELL_SIZE + PIECE_OFFSET, MARGIN + i * CELL_SIZE + PIECE_OFFSET, PIECE_SIZE, PIECE_SIZE);
                } else if (POSITIONS[i][j] == WHITE) {
                    g.setColor(Color.WHITE);
                    g.fillOval(MARGIN + j * CELL_SIZE + PIECE_OFFSET, MARGIN + i * CELL_SIZE + PIECE_OFFSET, PIECE_SIZE, PIECE_SIZE);
                }
            }
        }
    }

    public void mouseClicked(MouseEvent e) {
        if (gameOver) {
            return;
        }
        int x = e.getX();
        int y = e.getY();
        if (x < MARGIN - PIECE_OFFSET || x > MARGIN + (COLS - 1) * CELL_SIZE + PIECE_OFFSET ||
            y < MARGIN - PIECE_OFFSET || y > MARGIN + (ROWS - 1) * CELL_SIZE + PIECE_OFFSET) {
            return;
        }
        int row = Math.round((float) (y - MARGIN) / CELL_SIZE);
        int col = Math.round((float) (x - MARGIN) / CELL_SIZE);
        if (POSITIONS[row][col] != EMPTY) {
            return;
        }
        POSITIONS[row][col] = currentPlayer;
        repaint();
        if (checkWin(row, col)) {
            gameOver = true;
            JOptionPane.showMessageDialog(this, (currentPlayer == BLACK ? "Black" : "White") + " wins!");
        } else if (checkDraw()) {
            gameOver = true;
            JOptionPane.showMessageDialog(this, "Draw!");
        } else {
            currentPlayer = (currentPlayer == BLACK ? WHITE : BLACK);
        }
    }

    public void mousePressed(MouseEvent e) {}
    public void mouseReleased(MouseEvent e) {}
    public void mouseEntered(MouseEvent e) {}
    public void mouseExited(MouseEvent e) {}

    private boolean checkWin(int row, int col) {
        int count = 1;
        for (int i = row - 1; i >= 0 && POSITIONS[i][col] == currentPlayer; i--) {
            count++;
        }
        for (int i = row + 1; i < ROWS && POSITIONS[i][col] == currentPlayer; i++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        for (int j = col - 1; j >= 0 && POSITIONS[row][j] == currentPlayer; j--) {
            count++;
        }
        for (int j = col + 1; j < COLS && POSITIONS[row][j] == currentPlayer; j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        for (int i = row - 1, j = col - 1; i >= 0 && j >= 0 && POSITIONS[i][j] == currentPlayer; i--, j--) {
            count++;
        }
        for (int i = row + 1, j = col + 1; i < ROWS && j < COLS && POSITIONS[i][j] == currentPlayer; i++, j++) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        count = 1;
        for (int i = row - 1, j = col + 1; i >= 0 && j < COLS && POSITIONS[i][j] == currentPlayer; i--, j++) {
            count++;
        }
        for (int i = row + 1, j = col - 1; i < ROWS && j >= 0 && POSITIONS[i][j] == currentPlayer; i++, j--) {
            count++;
        }
        if (count >= 5) {
            return true;
        }
        return false;
    }

    private boolean checkDraw() {
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                if (POSITIONS[i][j] == EMPTY) {
                    return false;
                }
            }
        }
        return true;
    }
}

2. 创建一个主类，用于启动程序。

import javax.swing.*;

public class Main {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Five in a Row");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(new ChessBoard());
        frame.pack();
        frame.setVisible(true);
    }
}
