这不是最漂亮的方式，但它至少会给你一个想法：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public cl HexagonPattern extends JPanel {
    private static final long serialVersionUID = 1L;
    private static final int ROWS = 7;
    private static final int COLUMNS = 7;
    private HexagonButton[][] hexButton = new HexagonButton[ROWS][COLUMNS];
    public HexagonPattern() {
        setLayout(null);
        initGUI();
    }
    public void initGUI() {
        int offsetX = -10;
        int offsetY = 0;
        for(int row = 0; row < ROWS; row++) {
            for(int col = 0; col < COLUMNS; col++){
                hexButton[row][col] = new HexagonButton(row, col);
                hexButton[row][col].addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent e) {
                        HexagonButton clickedButton = (HexagonButton) e.getSource();
                        System.out.println("Button clicked: [" + clickedButton.getRow() + "][" + clickedButton.getCol() + "]");
                    }
                });
                add(hexButton[row][col]);
                hexButton[row][col].setBounds(offsetY, offsetX, 105, 95);
                offsetX += 87;
            }
            if(row%2 == 0) {
                offsetX = -52;
            } else {
                offsetX = -10;
            }
            offsetY += 76;
        }
    }
    public static void main(String[] args) {
        HexagonPattern hexPattern = new HexagonPattern();
        JFrame frame = new JFrame();
        frame.setTitle("Hexagon Pattern");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocation(new Point(700, 300));
        frame.add(hexPattern);
        frame.setSize(550, 525);
        frame.setResizable(false);
        frame.setVisible(true);
    }
    //Following cl draws the Buttons
    cl HexagonButton extends JButton {
        private static final long serialVersionUID = 1L;
        private static final int SIDES = 6;
        private static final int SIDE_LENGTH = 50;
        public static final int LENGTH = 95;
        public static final int WIDTH = 105;
        private int row = 0;
        private int col = 0;
        public HexagonButton(int row, int col) {
            setContentAreaFilled(false);
            setFocusPainted(true);
            setBorderPainted(false);
            setPreferredSize(new Dimension(WIDTH, LENGTH));
            this.row = row;
            this.col = col;
        }
        @Override
        public void paintComponent(Graphics g) {
            super.paintComponent(g);
            Polygon hex = new Polygon();
            for (int i = 0; i < SIDES; i++) {
                hex.addPoint((int) (50 + SIDE_LENGTH * Math.cos(i * 2 * Math.PI / SIDES)), //calculation for side
                        (int) (50 + SIDE_LENGTH * Math.sin(i * 2 * Math.PI / SIDES)));   //calculation for side
            }       
            g.drawPolygon(hex);
        }
        public int getRow() {
            return row;
        }
        public int getCol() {
            return col;
        }
    }
}

试试看！

这个程序包括 2 类：

HexagonButton，它使用 Graphics 将六边形绘制成JButton。当调用getRow或getCol时，它还返回行和列的值。

HexagonPattern，这是主类。它通过用setBounds(x, y, width, height)布局它们来制作图案。它使用ActionListener通过调用getRow和getCol来打印单击的六边形的坐标。

就像我说的，这不是最伟大的程序。如果你想让六边形变小，那么你必须改变很多变量。
