1.设计一个简单的学生管理系统（StudentManager）。主要功能包括： (1)学生信息的录入。主要包括：学号（no）、姓名（name）、年龄（age）、性别（gender）等； (2)学生信息的查询。根据学号、姓名、年龄和性别等查询学生的信息。注意：查询结果可能不唯一。 (3)学生信息的修改。根据学号查询到指定学生的信息，再用新的内容替换。 (4)学生信息的删除。根据学号删除指定学生的信息。 设计时，采用层次化设计法，将类分为界面层（ui）、功能层（business）和持久层（persistence）3层，放在不同子包中。整个系统的代码放在exe4_1包中。(1. Design a simple student management system (StudentManager). Key features include: (1) The entry of student information. Including: Student ID (no), name (name), aged (age), sex (gender) and the like (2) query the student information. According to school, name, age and sex inquiry student information.
