这篇文章主要为大家详细介绍了Java实现简单的学生教师管理系统,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实现学生教师管理系统的具体代码,供大家参考,具体内容如下
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
import java.text.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);
this.grade = grade;
this.group = group;
}
public Student() {
}
public int getGrade() {
return grade;
}
public void setGrade(int grade) {
this.grade = grade;
}
public String getGroup() {
return group;
}
public void setGroup(String group) {
this.group = group;
}
}
Teacher类
import java.text.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
import java.text.ParseException;
import java.text.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 = date.getTime();
long time1 = date1.getTime();
long age = (time1 - time) / 1000 / 60 / 60/ 24 / 365;
return (int)age;
}
}
