这期内容当中小编将会给大家带来有关java中怎么实现一个航空用户管理系统,文章内容丰富且以专业的角度为大家分析和叙述,阅读完这篇文章希望大家可以有所收获。
用户添加
2. 密码修改
3. 个人信息查看
4. 账号状态修改(禁用0、启用1)
5. 用户登录(被禁用账号无法登录并提示友好的消息)
6. 修改用户角色(设置取消管理员)
7. 用户列表
8. 查询指定办事处的员工
9. 删除用户
办事处添加
2. 办事处列表
注意:管理员具备以上所有功能,普通用户只有密码修改和个人信息查看功能
用户类(User):
id,账号(username),密码(passord),年龄(age),角色(role),邮箱(email),办事处id(officeID),账户状态(status)
办事处类(Office):
id,办公室名(officeName)
要求使用技术参数如下:
分支与循环
2.数组或ArrayList
3.方法
4.构造器
5.setter/getter
6.抽象类或接口
7.多态
8.Scanner类
题目中管理员与用户的功能实现不同,普通用户只有登录系统、密码修改与个人信息查看功能,而管理员实现的功能更多,包含了普通用户的所有功能,那么我可以在登录时就进行分辨,不同用户所获得的功能菜单界面不同。
管理员可以设置状态,如果状态为禁用则无法登录。(实现方法可以放在用户登录中)
默认管理员admin/admin123(可以设置一个初始化块,初始化块又称游离块,是一个没有名称的代码块,执行时间一般在创建对象执行构造器前先执行,并且执行次数取决于对象的创建次数,作用于将多个构造器中的重复代码提取到一起统一执行. )
个人信息查看只能查看个人的信息,没法看到其他用户的信息。(设置一个静态变量,登陆时的用户名存储在里面,个人信息查看通过该静态变量在信息存储中查找)
接口(这次的接口没有写好,可以将UserMange中的方法都放进接口中,在UserMange类中实现,OfficeMange类中也一样)
内容实现:
User类:
package com.softeem.j2106.work; public class User { private int id; private String username; private String passWord; private int age; private boolean role; private String email; private int officeID; private boolean status; public User() { } public User(int id, String username, String password, int age, boolean role, String email, int officeID, boolean status) { this.id = id; this.username = username; this.password = password; this.age = age; this.role = role; this.email = email; this.officeID = officeID; this.status = status; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public int getOfficeID() { return officeID; } public void setOfficeID(int officeID) { this.officeID = officeID; } public boolean isRole() { return role; } public void setRole(boolean role) { this.role = role; } public boolean isStatus() { return status; } public void setStatus(boolean status) { this.status = status; } @Override public String toString() { return "User{" + "id=" + id + ", username='" + username + '\'' + ", password='" + password + '\'' + ", age=" + age + ", role=" + role + ", email='" + email + '\'' + ", officeID=" + officeID + ", status=" + status + '}'; }}
office类:
package com.softeem.j2106.work; public class Office { private int officeID; private String officeName; public Office() { } public Office(int officeID, String officeName) { this.officeID = officeID; this.officeName = officeName; } public int getOfficeID() { return officeID; } public void setOfficeID(int officeID) { this.officeID = officeID; } public String getOfficeName() { return officeName; } public void setOfficeName(String officeName) { this.officeName = officeName; } @Override public String toString() { return "Office{" + "officeID=" + officeID + ", officeName='" + officeName + '\'' + '}'; }}
Inter接口:
package com.softeem.j2106.work; public interface Inter { public void ShowAll();}
usermange:
package com.softeem.j2106.work; import java.util.Objects; public class UserManage implements Inter{ private User[] users = new User[10]; private int index=1; { users[0] = new User(0,"admin","admin123",20,true,"@163.com",0,true); } public int sign(String username, String password) { for (int i = 0; i < users.length; i++) { User s = users[i]; if ((Objects.nonNull(s))&& s.getUsername().equals(username) && s.getPassword().equals(password)) { if ((s.isRole())&& s.isStatus()) { return 1; } else if ((!s.isRole()) && s.isStatus()) { return 0; } else if (!s.isStatus()){ return -2; } } } return -1; } public boolean add(User u) { if (index >= users.length) { return false; } users[index++] = u; return true; } public boolean updatePassword(String password) { for (int i = 0; i < users.length; i++) { User user = this.users[i]; if ((Objects.nonNull(user))&&user.getPassword() != null) { users[i].setPassword(password); return true; } } return false; } public User SearchByID(String username) { User user = new User(); for (User user1 : users) { if ((Objects.nonNull(user))&&user1.getUsername().equals(username)) { user = user1; break; } } return user; } public boolean changeStatus(String username, boolean status) { User user = SearchByID(username); if (user != null) { user.setStatus(status); return true; } return false; } public boolean changeAdmin(String username, boolean role) { User user = SearchByID(username); if (user != null) { user.setRole(role); return true; } return false; } public boolean searchofficeID(int officeId) { for (User user : users) { if ((Objects.nonNull(user))&&officeId == user.getOfficeID()) { System.out.println(user); return true; } } return false; } public boolean delete(int id) { for (int i = 0; i < users.length; i++) { User s = users[i]; if (Objects.nonNull(s) && Objects.equals(s.getId(), id)) { //将当前元素置为空// stus[i] = null; //后续的元素前移 覆盖空白位置(避免碎片化) System.arraycopy(users, i + 1, users, i, users.length - index - 1); index--; return true; } } return false; } @Override public void ShowAll() { for (User user : users) { if (user != null) { System.out.println(user); } } }}
officeMange类:
package com.softeem.j2106.work; public class OfficeMange implements Inter { private static Office[] off = new Office[10]; private int index; public boolean officeAdd(Office o) { if (index >= off.length) { return false; } off[index++] = o; return true; } @Override public void ShowAll() { for (Office office : off) { if (office != null) { System.out.println(office); } } }}
tset类:(实现)
package com.softeem.j2106.work; import java.util.Scanner; public class Test { static String loginname; static UserManage a = new UserManage(); static OfficeMange b = new OfficeMange(); static Scanner sc = new Scanner(System.in); public static void start() { msg("==============SOFTEEM用户登录=============="); msg("========================================="); msg("请输入账号:"); String username = sc.next(); loginname = username; msg("请输入密码:"); String password = sc.next(); if (a.sign(username, password) == 1) { sign1(); } else if (a.sign(username, password) == 0) { sign2(); } else if (a.sign(username, password) == -1) { msg("登录失败!"); start(); } else if (a.sign(username, password) == -2) { msg("账号被禁用!"); start(); } } public static void sign1() { msg("=========SOFTEEM管理员管理系统========="); msg("[1] 用户添加"); msg("[2] 密码修改"); msg("[3] 个人信息查看"); msg("[4] 账号状态修改"); msg("[5] 修改用户角色"); msg("[6] 用户列表"); msg("[7] 查询指定办事处的员工"); msg("[8] 删除员工"); msg("[9] 用户登录"); msg("[10] 办事处添加"); msg("[11] 办事处列表"); msg("[0] 退出系统"); msg("===================================="); Scanner sc = new Scanner(System.in); int i = sc.nextInt(); switch (i) { case 1: addUser(); break; case 2: pwd(); sign1(); break; case 3: selectbyid(); sign1(); break; case 4: updateStatus(); break; case 5: updateRole(); break; case 6: listUser(); break; case 7: Search(); break; case 8: delUser(); break; case 9: start(); break; case 10: addOffice(); break; case 11: listOffice(); break; case 0: msg("谢谢使用,再见!"); //系统退出(关闭JVM) System.exit(0); break; default: msg("指令错误,请重新输入"); sign1(); break; } } public static void sign2() { msg("==========SOFTEEM用户管理系统=========="); msg("[1] 个人查看"); msg("[2] 密码修改"); msg("[0] 退出系统"); msg("===================================="); Scanner sc = new Scanner(System.in); int i = sc.nextInt(); switch (i) { case 1: selectbyid(); sign2(); break; case 2: pwd(); sign2(); break; case 0: msg("谢谢使用,再见!"); //系统退出(关闭JVM) System.exit(0); break; default: msg("指令错误,请重新输入"); start(); break; } } public static void selectbyid() { User u = a.SearchByID(loginname); if (u == null) { msg("您输入的用户id不存在"); } System.out.println(u); } public static void pwd() { msg("请输入新密码:"); String password = sc.next(); if (a.updatePassword(password)) { msg("修改成功"); } else { msg("修改失败"); } } private static void addUser() { msg("请输入ID:"); int id = sc.nextInt(); msg("请输入用户名:"); String name = sc.next(); msg("请输入密码:"); String password = sc.next(); msg("请输入年龄:"); int age = sc.nextInt(); msg("设置为管理员【1】是: 【0】否"); int i = sc.nextInt(); boolean role = true; if (i == 1){ role = true; }else if (i == 0){ role = false; }else { msg("请输入正确的指令"); } msg("请输入邮箱:"); String emial = sc.next(); msg("请输入办事处ID:"); int officeid = sc.nextInt(); msg("设置状态【1】启用: 【0】禁用"); int j = sc.nextInt(); boolean status = true; if (j == 1){ status = true; }else if (j == 0){ status = false; }else { msg("请输入正确的指令"); } User u = new User(id, name, password, age, role, emial, officeid, status); if (a.add(u)) { msg("添加成功!!"); } else { msg("容量不足!!"); } //返回主菜单 sign1(); } public static void addOffice(){ msg("请输入officeID:"); int id = sc.nextInt(); msg("请输入办事处名:"); String name = sc.next(); Office o = new Office(id,name); if (b.officeAdd(o)){ msg("添加成功!!"); } else { msg("容量不足!!"); } sign1(); } public static void updateStatus() { msg("请输入修改用户名:"); String username = sc.next(); msg("请修改用户的账户状态(禁用0/启用1):"); int j = sc.nextInt(); boolean status = true; if (j == 1){ status = true; }else if (j == 0){ status = false; }else { msg("请输入正确的指令"); } if (a.changeStatus(username, status)) { msg("修改成功"); } else { msg("修改失败"); } sign1(); } public static void updateRole() { msg("请输入修改用户名:"); String username = sc.next(); msg("请修改用户的角色信息(禁用0/启用1):"); int i = sc.nextInt(); boolean role = true; if (i == 1){ role = true; }else if (i == 0){ role = false; }else { msg("请输入正确的指令"); } if (a.changeAdmin(username, role)) { msg("修改成功"); } else { msg("修改失败"); } sign1(); } public static void delUser() { msg("请输入ID:"); int Id = sc.nextInt(); if (a.delete(Id)) { msg("删除成功!!"); } else { msg("用户不存在!!"); } //返回上一级 sign1(); } public static void listUser() { a.ShowAll(); //返回上一级 sign1(); } public static void listOffice(){ b.ShowAll(); sign1(); } private static void Search() { msg("请输入ID:"); int ID = sc.nextInt(); if (a.searchofficeID(ID)){ }else { msg("未知查询"); } sign1(); } public static void msg(String msg) { System.out.println(msg); } public static void main(String[] args) { start(); }}
