Java实现高校教务系统
作者：LIiuxb
这篇文章主要为大家详细介绍了Java实现高校教务系统，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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;
}
