今天为大家分享一个java语言编写的公司财务管理系统，目前系统已经完成了主要功能，后续会进一步完善。整个系统界面漂亮，有完整得源码，希望大家可以喜欢。喜欢的帮忙点赞和关注。一起编程、一起进步

开发环境

开发语言为Java，开发环境Eclipse或者IDEA都可以。数据库采用：MySQL。运行主程序，或者执行打开JAR文件即可以运行本程序。

系统框架

利用JDK自带的SWING框架开发，不需要安装第三方JAR包。MySQL数据库，纯窗体模式，直接运行Main文件即可以。同时带有详细得设计文档

运行方法

1 运行Main.java文件

2 程序出现公司财务管理系统登陆的面板

系统主要功能

系统主要分为6个主要的模块：材料管理、订单管理、工程管理、员工信息管理、财务管理、汽车消费

1 材料管理：记录材料的使用情况，包括新增，删除，修改。材料使用记录以下一些字段：

记录编号、材料编号、数量、单价、供货商、日期、总价。

2 订单管理：订单的新增，删除，修改等功能。订单记录包括：客户、联系电话、规格、单价、数量、预付款

3 员工管理：员工的新增、删除、查询和修改。员工信息包括：用户工号、姓名、性别、电话、地址、学历、出生日期。

4 工资管理：工资录入，查询和修改。工资信息包括：姓名，身份证、籍贯、月份、工资

5 财务管理：财务管理包括财务的新增、删除、修改等操作。财务信息包括：记录编号、客户名、联系电话、规格、单价、数量、预付款、总报价剩余款、发生日期。

6 汽车消费：记录公司汽车消费情况。汽车消费包含字段信息包括：记录编号、车牌号、消费日期、金额。

7 对所有功能模块的单据进行打印操作。
