控制台编写购物中心会员管理系统

控制台编写购物中心会员管理系统

分析需求

要求要有管理员界面和用户界面，管理员还必须能管理用户信息实现增删改。所以，我创建了四个类，分别是测试类、管理员类、会员类、数据类。
其中，数据类为管理员信息与会员信息的存储类，也作为管理员类、会员类的父类。

数据类代码

public class Data {
	public static String username;// 登录的用户名

	public static String password;// 登录的密码

	public static String[] user = { "admin", "张三", "小花", "李四", "王五", "溜溜" };//登录用户名

	public static String[] pwd = { "123", "123", "123", "123", "123", "123" };//登录用的密码

	public static String[] sex = { "", "男", "女", "男", "男", "女" };//用户性别

	public static int[] age = { 0, 18, 20, 19, 21, 22 };//用户年龄

	public static String getUsername() {
		return username;
	}

	public static void setUsername(String username) {
		Data.username = username;
	}

	public static String getPassword() {
		return password;
	}

	public static void setPassword(String password) {
		Data.password = password;
	}

	public boolean judge(String username, String password, int i) {//登录时判断用户名与密码

		this.username = username;
		this.password = password;

		if (i == 0 && this.user[0].equals(username)
				&& this.pwd[0].equals(password)) {
			return true;
		} else if (i != 0) {
			for (int y = 1; y <= user.length; y++) {
				if (this.user[y].equals(username) && this.pwd[y].equals(password)) {
					
					User.i = y;
					return true;
				}
			}
		}
		return false;
	}

	public void homePage(int key) {//首页

		switch (key) {
		case 1:
			Admin a = new Admin();
			a.login();
			break;
		case 2:
			User s = new User();
			s.login();
			break;
		case 3:
			System.out.println("已退出系统");
			System.exit(0);
			return;
		default:
			System.out.println("输入错误,请重新输入");
			break;
		}
	}
}

管理员类代码

public class Admin extends Data {
	Scanner input = new Scanner(System.in);

	public void login() {//管理员登录
		for (int i = 0; i < 3; i++) {
			System.out.print("请输入用户名：");
			String username = input.next();
			System.out.print("请输入密码：");
			String password = input.next();
			if (super.judge(username, password, 0)) {
				System.out.println("登陆成功");
				AdminHomePage();
			} else {
				System.out.println("用户名或密码错误，请重试");
				if (i == 2) {
					System.out.println("对不起，登录已超时！");
					System.exit(0);
				}
			}
		}

	}

	public void AdminHomePage() {//管理员首页
		System.out.println("欢迎进入管理员管理界面：");
		while (true) {
			System.out.println("1.查询会员信息");
			System.out.println("2.增加会员信息");
			System.out.println("3.删除会员信息");
			System.out.println("4.修改会员信息");
			System.out.println("5.退出");
			System.out.print("请选择管理员业务：");
			switch (input.nextInt()) {
			case 1:
				information();
				break;
			case 2:
				add();
				information();
				break;
			case 3:
				delete();
				information();
				break;
			case 4:
				modify();
				information();
				break;
			case 5:
				Demo01 d = new Demo01();
				d.main(user);
				break;
			default:
				System.out.println("选择错误，请重新选择");
				break;
			}
		}

	}

	public void information() {//查询会员信息
		System.out.println("会员信息如下：");
		if (user.length > 1) {
			System.out.println("编号\t姓名\t密码\t性别\t年龄");
			for (int i = 1; i < super.user.length; i++) {
				System.out.println(i + "\t" + super.user[i] + "\t"
						+ super.pwd[i] + "\t" + super.sex[i] + "\t"
						+ super.age[i]);
			}
		} else {
			System.out.println("还没有会员");
		}
	}

	public void add() {//添加会员信息
		String username = null;
		String password = null;

		String user1[] = new String[user.length + 1];
		String pwd1[] = new String[user.length + 1];
		String sex1[] = new String[user.length + 1];
		int age1[] = new int[user.length + 1];

		for (int i = 0; i < user1.length; i++) {
			if (i < user.length) {
				user1[i] = user[i];
				pwd1[i] = pwd[i];
				sex1[i] = super.sex[i];
				age1[i] = super.age[i];
			} else {
				user1[i] = username;
				pwd1[i] = password;
				sex1[i] = sex;
				age1[i] = age;
			}
		}

		user = new String[user1.length];
		pwd = new String[user1.length];

		}
	}

	public void delete() {//删除会员信息
		String user1[] = new String[user.length - 1];
		String pwd1[] = new String[user.length - 1];
		String sex1[] = new String[user.length - 1];
		int age1[] = new int[user.length - 1];
		
		System.out.print("请输入删除会员的编号：");
		int number = input.nextInt();// 要删除的编号
		level:
		for (int i = 0; i < user.length - 1; i++) {
			if (number > 0 && number < user.length) {
				if(i < number) {
					user1[i] = user[i];
					pwd1[i] = pwd[i];
					sex1[i] = super.sex[i];
					age1[i] = super.age[i];
				}else if(i >= number) {
//					System.out.println(user.length);
//					System.out.println(user1.length);

			} else {

	}

}

用户类代码

public class User extends Data {
	public static int i = 0;//通过它传递用户编号

	Scanner input = new Scanner(System.in);

	public void login() {//登录
		for (int i = 0; i < 3; i++) {
			System.out.print("请输入用户名：");
			String username = input.next();
			System.out.print("请输入密码：");

				System.out.println("登陆成功");
				AdminHomePage();
			} else {
				System.out.println("用户名或密码错误，请重试");
			}
		}
	}

	public void AdminHomePage() {//用户首页
		System.out.println("欢迎进入管理员管理界面：");
		while (true) {

	}

	public void information() {//查看用户信息

	}

	public void lucky() {//抽奖

测试类

public class Demo01 {
	
	public static void main(String[] args) {
		System.out.println("-----欢迎进入我行我素购物管理系统-----");
		Data d = new Data();
		Scanner input = new Scanner(System.in);
		while(true){

			System.out.println("1.管理员登录");
			System.out.println("2.会员登录");
			System.out.println("3.退出");
			System.out.println("请选择登录 菜单：");
			
			d.homePage(input.nextInt());
		}
	}
}
