这篇文章主要介绍java实现捕鱼达人游戏的案例，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
具体内容如下
效果图如下：
源代码分享：
测试类：
package game;
import java.awt.image.BufferedImage;
import java.io.File;

//创建窗口图标,绝对路径
BufferedImage icon = ImageIO.read(new File("E:/New_life/fish_game/resource/images/fish07_03.png"));

}
}还有一个计分板没有写上，没有开始结束的界面，渔网是静态的，这些功能都还没有实现，日后更新。
