求一段JAVA编写的贪吃蛇小程序源代码

用MVC方式实现的贪吃蛇游戏,共有4个类。运行GreedSnake运行即可。主要是观察者模式的使用,我已经添加了很多注释了。

1、

/*

* 程序名称:贪食蛇

* 原作者:BigF

* 修改者:algo

* 说明:我以前也用C写过这个程序,现在看到BigF用Java写的这个,发现虽然作者自称是Java的初学者,

* 但是明显编写程序的素养不错,程序结构写得很清晰,有些细微得地方也写得很简洁,一时兴起之

* 下,我认真解读了这个程序,发现数据和表现分开得很好,而我近日正在学习MVC设计模式,

* 因此尝试把程序得结构改了一下,用MVC模式来实现,对源程序得改动不多。

* 我同时也为程序增加了一些自己理解得注释,希望对大家阅读有帮助。

怎么包装贪吃蛇项目

思路:

首先你要有一条贪吃蛇,哎,就是玩儿。

1.先用Java敲一个贪吃蛇小游戏的程序。

2.把Java程序打包成jar文件包,把jar包打包成exe应用程序

知道思路以后,接下来按照我的详细步骤走,能少踩坑,别问我怎么知道的!!!

一、Java“敲一个”贪吃蛇小游戏

废话不多说,本篇主要讲从java项目到exe应用程序,Java项目的代码在我上传的资源当中——代码-greedy snack.zip

二、将项目打成jar包

如何打包成jar包?

1.手动打可直接执行的jar包(本次不使用)2. 使用intellij idea工具打可直接执行的jar包

1) 打开项目

2)点击 File — 选择 Project Structure,找到“Artifacts” 点击 “+” 选择“JAR” —“Empty”。

3) Name栏可以填入自定义的名字,Output ditectory选择jar包生成目标目录,Available Elements里双击需要添加到jar包的文件,即可添加到左边的jar包目录,如图:

4)点击Create Manifest,选择放置MANIFEST.MF的文件路径,直接默认项目根目录就行,点击OK。

5) 点击Main Class后面选择按钮, 弹出框中选择需要运行程序入口main函数,点击OK,点击OK。

6) 点击菜单中“Build” - "Build Artifacts", 双击弹出框中待生成jar包下面的build即可,如下图

7)至此使用Intellij idea生成可直接执行jar包就完成了。

8)查看生成的jar包,并运行jar包。命令行运行jar包

java -jar xxx.jar

复制代码

三、打包成为exe应用程序

这里首先你要有:

上面生成的jar包 greedy snack.jar

工具:exe4j,一个将jar转换成exe的工具 链接:… 提取码:ijdv

1)安装exe4j,打开安装好的exe4j,进行注册

注册码:L-g782dn2d-1f1yqxx1rv1sqd

2) 点击 Next, 选择JAVA转EXE

3) Next,填入自定义的名字和生成目标文件目录

4) 继续Next,选择启动模式、设置程序名称和程序图标

5) 下方有个选项,需要设置打包后的程序兼容32和64位系统。

勾选,然后Next。

6)然后Next,直到出现如下界面,开始选择jar包以及配置

在VM参数配置的地方加上:-Dfile.encoding=utf-8

添加jar包

设置启动类

Next 配置JRE

Next 选择 Client VM

7)Next 直到如下图界面

桌面多了一个贪吃蛇小游戏3.0.exe文件,至此我们就成功的做出了一个Java贪吃蛇小游戏的exe应用程序
