以下是一个关于JAVA职教本科课程设计的示例：

题目：学生成绩管理系统

要求：

  1. 使用Java编写一个学生成绩管理系统，能够实现学生信息的录入、查询、修改和删除功能。
  2. 学生信息包括学号、姓名、性别、年龄、班级和成绩等字段。
  3. 系统能够根据学号查询学生信息，并能够根据成绩进行排序。
  4. 系统能够实现学生信息的修改和删除操作。
  5. 系统需要有用户登录功能，只有登录成功的用户才能使用系统。
  6. 系统需要有数据持久化功能，能够将学生信息保存到文件中，并能够从文件中读取学生信息。

设计思路：

  1. 创建一个Student类，包含学号、姓名、性别、年龄、班级和成绩等字段，并提供相应的get和set方法。
  2. 创建一个StudentManagementSystem类，作为程序的入口类，包含主方法和用户登录功能。
  3. 在StudentManagementSystem类中，创建一个ArrayList来存储学生信息，并提供相应的录入、查询、修改和删除功能。
  4. 使用文件操作功能，将学生信息保存到文件中，并能够从文件中读取学生信息。

代码示例：

以上就是一个简单的学生成绩管理系统的实现示例。可以根据实际需求进行适当的修改和扩展
