用java语言编写一个学生宿舍管理系统

好的，学生宿舍管理系统主要包括以下几个模块：

1. 学生信息管理模块：包括学生基本信息（学号、姓名、性别、年龄、班级等）的增删改查功能。

2. 宿舍信息管理模块：包括宿舍基本信息（宿舍号、楼层、床位数等）的增删改查功能。

3. 入住管理模块：包括学生入住宿舍、退宿等功能。

4. 维修管理模块：包括宿舍维修申报、维修记录查询等功能。

5. 统计报表模块：包括学生入住情况、宿舍维修情况等统计报表功能。

下面是一个简单的学生宿舍管理系统Java代码示例：

import java.util.ArrayList;
import java.util.Scanner;

public class DormitoryManagementSystem {

    // 定义ArrayList集合存储学生和宿舍信息
    private static ArrayList<Student> students = new ArrayList<>();
    private static ArrayList<Dormitory> dormitories = new ArrayList<>();

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        while (true) {
            System.out.println("欢迎使用学生宿舍管理系统！");
            System.out.println("1. 学生信息管理");
            System.out.println("2. 宿舍信息管理");
            System.out.println("3. 入住管理");
            System.out.println("4. 维修管理");
            System.out.println("5. 统计报表");
            System.out.println("0. 退出系统");
            System.out.print("请选择操作：");
            int choice = input.nextInt();

            switch (choice) {
                case 0:
                    System.out.println("谢谢使用，再见！");
                    System.exit(0);
