Java学生教师管理系统

Java学生教师管理系统

需求：

我们可以通过管理系统对学生和教师进行管理
对象学生和教师进行增删改查等的功能

1. Student和Teacher的父类
2. Student类
3. Teacher类
4. Utils工具类
5. 测试类

Student和Teacher的父类

public class Person {private String id; // 编号private String name; // 姓名private String IDcard; // 身份证private String sex; // 性别private String birthday; // 生日private int age; //年龄private String site; //地址private String phone; // 电话public Person() {}public Person(String id, String name, String IDcard, String sex, String birthday, String site, String phone) throws ParseException {this.id = id;this.name = name;this.IDcard = IDcard;this.sex = sex;this.birthday = birthday;this.age = Utils.birthdayToAge(birthday);this.site = site;this.phone = phone;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getIDcard() {return IDcard;}public void setIDcard(String IDcard) {this.IDcard = IDcard;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public String getBirthday() {return birthday;}public void setBirthday(String birthday) throws ParseException {this.birthday = birthday;this.age = Utils.birthdayToAge(birthday);}public int getAge() {return age;}public String getSite() {return site;}public void setSite(String site) {this.site = site;}public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}
}

Student类

ParseException;public class Student extends Person {private int grade; // 成绩private String group; // 班级// 学生号，姓名，身份证，性别，生日，地址，手机号,成绩，班级public Student(String id, String name, String IDcard, String sex, String birthday, String site, String phone, int grade, String group) throws ParseException {super(id, name, IDcard, sex, birthday, site, phone);ade = up = group;}public Student() {}public int getGrade() {return grade;}public void setGrade(int grade) {ade = grade;}public String getGroup() {return group;}public void setGroup(String group) {up = group;}
}

Teacher类

ParseException;public class Teacher extends Person{private String career; // 专业private String salary; // 工资// 教师号，姓名，身份证，性别，生日，地址，手机号，专业，工资public Teacher(String id, String name, String IDcard, String sex, String birthday, String site, String phone, String career, String salary) throws ParseException {super(id, name, IDcard, sex, birthday, site, phone);this.career = career;this.salary = salary;}public Teacher() {}public String getCareer() {return career;}public void setCareer(String career) {this.career = career;}public String getSalary() {return salary;}public void setSalary(String salary) {this.salary = salary;}
}

根据生日计算年龄的一个静态工具类

Utils

ParseException;
SimpleDateFormat;
import java.util.Date;public class Utils {public static int birthdayToAge(String birthday) throws ParseException {SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd");Date date = sdf.parse(birthday);Date date1 = new Date();long time = Time();long time1 = Time();long age = (time1 - time) / 1000 / 60 / 60/ 24 / 365;return (int)age;}
}
