java—连连看-实现封装

1、封装

Chess.java

package Linkup;

/**
 * 棋子封装类

public class Chess {

	// 图片的 状态 //1.....20
	// 0表示消掉

	private int status;

	public Chess(int status) {
		this.status = status;
	}

	public int getStatus() {
		return status;
	}

	public void setStatus(int status) {
		this.status = status;
	}

}

Param.java

package Linkup;

import java.awt.Image;

import javax.swing.ImageIcon;

public class Param {

	//游戏总行数与总列数
	public static int rows=8;
	public static int cols=10;

	//棋子图标 宽与高
	public static int chessWidth=55;
	public static int chessHeight=55;

	//棋盘到边界的距离
	public static int marginWidth = 200;
	public static int marginHeight = 150;

	//游戏的背景图片
	public static Image imageBackground = new ImageIcon("Images/build/BackGround.jpg").getImage();

	public static Image[] chessImage = new Image[20];
	static {
		for (int i = 0; i < chessImage.length; i++) {
			chessImage[i] = new ImageIcon("Images/build/" + (i + 1) + ".png").getImage();
		}
	}

}

MapPanel.java

package Linkup;

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Stroke;

import java.util.Random;

import javax.swing.JPanel;

/**

public class MapPanel extends JPanel implements MouseListener {
	Chess[][] arr = new Chess[Param.rows][Param.cols];
	// 粗线条
	Stroke stroke = new BasicStroke(3.0f);

	public MapPanel() {

		this.addMouseListener(this);
	}

	public void initArr() {

		Random random = new Random();
		for (int i = 1; i <= 20; i++) {
			int count = 0;

					count++;
				}
			}
		}

	}

	@Override
	public void paint(Graphics g) {
		super.paint(g);

		g.setColor(Color.green);
		Font font = new Font("宋体", Font.BOLD, 28);
		g.setFont(font); // 设置字体颜色和字体大小

		g.drawImage(Param.imageBackground, 0, 0, this);// 设置背景图片

		g.drawString("连连看", 400, 100);

		for (int i = 0; i < arr.length; i++) {
			for (int j = 0; j < arr[i].length; j++) {
				int x = j * Param.chessWidth;
				int y = i * Param.chessHeight;
				g.drawImage(Param.chessImage[arr[i][j].getStatus() - 1], x
						+ Param.marginWidth, y + Param.marginHeight, this);
			}
		}

	}

	@Override
	public void mouseClicked(MouseEvent e) {}

	@Override
	public void mousePressed(MouseEvent e) {
		if (e.getModifiers() != InputEvent.BUTTON1_MASK) {
			return;
		}

		int x = e.getX();
		int y = e.getY();

		int X = (x - Param.marginWidth) / Param.chessWidth;
		X = X * Param.chessWidth + Param.marginWidth;
		int Y = (y - Param.marginHeight) / Param.chessHeight;
		Y = Y * Param.chessHeight + Param.marginHeight;

		Graphics g = getGraphics();
		Graphics2D g2d = (Graphics2D) g;
		g2d.setStroke(stroke);
		g2d.setColor(Color.blue);
		if ((x >= Param.marginWidth && x <= Param.marginWidth + Param.cols
				* Param.chessWidth)
				&& (y >= Param.marginHeight && y <= Param.marginHeight
						+ Param.rows * Param.chessHeight)) {
			g2d.drawRect(X, Y, Param.chessWidth, Param.chessHeight);
		}

	}

	@Override
	public void mouseReleased(MouseEvent e) {}

	@Override
	public void mouseEntered(MouseEvent e) {}

	@Override
	public void mouseExited(MouseEvent e) {}

}

TestGUI.java

package Linkup;

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Image;
import java.util.Random;

import javax.swing.ImageIcon;
import javax.swing.JFrame;

public class TestGUI extends JFrame {
	MapPanel mapPanel = new MapPanel();

	public TestGUI() {
		this.add(mapPanel);
		this.setTitle("连连看");// 设置 标题

		this.setSize(1000, 650);// 设置宽高

		this.setLocationRelativeTo(null);// 自动适配到屏幕中间

		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);// 设置关闭模式
		this.setResizable(false);

		this.setVisible(true);// 设置可见

		ImageIcon imageIcon = new ImageIcon("Images/Photos/serverstop.gif");
		Image image = imageIcon.getImage();
		this.setIconImage(image);// 设置连连看窗体图标
	}

	public static void main(String[] args) {

		new TestGUI();

	}
}

通过鼠标点击，选中该图标，在图标外加一层边框
