Java實現簡單的學生教師管理系統
本文實例為大傢分享瞭Java實現學生教師管理系統的具體代碼，供大傢參考，具體內容如下
需求：
我們可以通過管理系統對學生和教師進行管理
對象學生和教師進行增刪改查等的功能
1、Student和Teacher的父類
2、Student類
3、Teacher類
4、Utils工具類
5、測試類
Student和Teacher的父類
public class Person {
private String id; // 編號
private String name; // 姓名
private String IDcard; // 身份證
private String sex; // 性別
private String birthday; // 生日
private int age; //年齡
private String site; //地址
private String phone; // 電話
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類
import java.text.ParseException;
public class Student extends Person {
private int grade; // 成績
private String group; // 班級
// 學生號，姓名，身份證，性別，生日，地址，手機號,成績，班級
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類
import java.text.ParseException;
public class Teacher extends Person{
private String career; // 專業
private String salary; // 工資
// 教師號，姓名，身份證，性別，生日，地址，手機號，專業，工資
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;
}
}
根據生日計算年齡的一個靜態工具類
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;
}
}
測試類
