本文实例为大家分享了Java实现高校教务系统的具体代码,供大家参考,具体内容如下
需求:建立一个教务管理系统,为学生和教师提供不同的功能
//简单利用javase基础做出后端框架,后期再利用mysql数据库以及Spring cloud完善
父类:
public class people { private String name; private int age; private String sex; public people() { } public people(String name, int age, String sex) { this.name = name; this.age = age; this.sex = sex; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } }
学生类:
public class student extends people{ private String classname; private String studyid; private String chengji=""; private String kebiao=""; private String jiguo=""; private String studypassword; public student() { } public student(String name, int age, String sex, String classname, String studyid, String studypassword) { super(name, age, sex); this.classname = classname; this.studyid = studyid; this.studypassword = studypassword; } public String getClassname() { return classname; } public void setClassname(String classname) { this.classname = classname; } public String getStudyid() { return studyid; } public void setStudyid(String studyid) { this.studyid = studyid; } public String getStudypassword() { return studypassword; } public void setStudypassword(String studypass) { this.studypassword = studypassword; } public String getChengji() { return chengji; } public void setChengji(String chengji) { this.chengji = chengji; } public String getKebiao() { return kebiao; } public void setKebiao(String kebiao) { this.kebiao = kebiao; } public String getJiguo() { return jiguo; } public void setJiguo(String jiguo) { this.jiguo = jiguo; } }
教师类:
public class teacher extends people{ private String teachclass; private String teachid; private String teachpassword; public teacher() { } public teacher(String name, int age, String sex, String teachclass, String teachid, String teachpassword) { super(name, age, sex); this.teachclass = teachclass; this.teachid = teachid; this.teachpassword = teachpassword; } public String getTeachclass() { return teachclass; } public void setTeachclass(String teachclass) { this.teachclass = teachclass; } public String getTeachid() { return teachid; } public void setTeachid(String teachid) { this.teachid = teachid; } public String getTeachpassword() { return teachpassword; } public void setTeachpassword(String teachpassword) { this.teachpassword = teachpassword; } }
