基于Java的高校教务系统（简略版）

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;
    }

   
}
