本文为大家分享了java实现工资管理简单程序的具体代码，供大家参考，具体内容如下
程序总体说明（ReadMe）：
总体分为四部分:
管理程序(staffmanagment.java)：
- 在这里面使用了arraylist泛型来存放数据
- 博主正在想办法把数据放进mysql，这样读取会更方便，而且数据不会消失
- 当然(也可以把数据存入txt文件)

界面模块(SalarySystem.java)
- 对不同员工的工资最低进行了限制，毕竟法律规定了不能给太低
- 年龄也是（至少得成年吧——你懂的）
- 职位还可以安排更多

接下来的想法是把重复的员工去除，想先通过提醒使用者导入员工后，删除原有员工文件，然后在使用者退出前提示导入员工名单进行解决可能出现的员工重复问题
