使用Java写个福字

        最近在更新一些教学案例,突然想起每年支付宝都有一个扫福活动,就想着能不能用程序写一个福字，显而易见这当然可以,于是就有了这篇博文

其实内容很简单,主要就是三个类,一个是字体工具类,二是图片工具类,三是生成福字主类,效果如下

import java.awt.*;

public class FontUtil {
    public static void drawWord(Graphics g,String str,Color color,int size,int x,int y,String font){
        g.setColor(color);
        g.setFont(new Font(font,Font.BOLD,size));
        g.drawString(str,x,y);
    }
}

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class ImgTool {

    //提取图片工具1
    public static BufferedImage getimg(String path){
        BufferedImage img=null;
        try {
            img= ImageIO.read(new File(path));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return img;
    }

    //工具2
    public static Image getImage(String filename){
        return Toolkit.getDefaultToolkit().getImage(filename);
    }
}

import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.image.BufferedImage;
import java.util.Arrays;
import java.util.List;

public class RandFu extends JFrame {
    List colorList;
    List arrayList;
    Integer index, fontRandom;
    BufferedImage bg = null;

    public RandFu() {
        arrayList = Arrays.asList("楷体", "宋体", "华文琥珀", "华文行楷", "幼圆", "华文新魏", "华文彩云", "隶书");
        fontRandom = (int) ((Math.random() * 10) % 8);
        System.out.println("字体：" + arrayList.get(fontRandom));
        bg = ImgTool.getimg("src/cn/img/bg.jpg");
        //  初始化
        colorList = Arrays.asList(Color.gray, Color.black, Color.PINK, Color.orange, Color.RED);
        index = (int) ((Math.random() * 10) % 5);
        System.out.println("字体颜色" + index);
        setSize(600, 600);
        setIconImage(ImgTool.getImage("src/cn/img/fu.png"));
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
        setBackground(Color.red);

        //  键盘监听
        //  设置面板键盘监听
        this.addKeyListener(new KeyAdapter() {
            //  重写键盘监听方法
            @Override
            public void keyPressed(KeyEvent e) {
                //  判断是否是空格
                if (e.getKeyCode() == KeyEvent.VK_SPACE) {
                    reGame();
                }
            }
        });

    }
    //  重启
    public void reGame() {
        //  关闭当前窗口
        this.dispose();
        //  开启新窗口
        String[] args = {};
        main(args);
    }

    @Override
    public void paint(Graphics g) {
        //  画背景
        g.drawImage(bg, 15, 50, 570, 535, null);
        FontUtil.drawWord(g, "福", colorList.get(index), 250, 163, 400, arrayList.get(fontRandom));
        //  repaint();
    }

    public static void main(String[] args) {
        RandFu randFu = new RandFu();
    }
}
