测试与结果：

计算机维护管理系统 java的代码

你这个程序不算大。

但有很多地方的信息很不明确。比如说：你的数据库系统是什么？表结构？

如果说你想就靠分白拿这么多功能的JAVA代码应该也是不可能的。

建议你一个模块一个模块的问。在别人的帮助下你再想办法自己整合一下。

这样的题一般大学做毕业设计应该可以了。做出来都可以卖钱的!!

java的代码分享网站有哪些？

1. java2s

这个网站非常好，分成三大类，分别是Example 、Products 、 Articles ，每个大类下又分别设许多小类，还有搜索功能，这样查找起来非常方便。。比如，如果要学习SWT/JFace，只要把Example下的SWT JFace Eclipse 研究一下也就可以了。另外，这个网站还有JavaScript DHTML 、 C# / C Sharp 、 C / ANSI-C 、 SQL / MySQL 等类。总之，非常好。

2. codeZoo

这是O'Reily旗下的，除了Java之外，还有Ruby、Python。

3. Java学习源代码检索系统

难得看见国产的，好歹也要支持一下，分类也算清楚。

4. Koders

是个综合查询的网站，不过它好像是从代码中查找关键词，包含的语言挺多的。

5. Resources for Java server-side developers

确切的说，它是一个资源收集的网站，代码查询并不多。不过它分类相当细，如Articles、Books、Examples、Extensions、Frameworks等类，你可以输入Spring或Hibernate作为关键词搜索一下看看。
