How to implement a simple student dormitory management system in Java?

Introduction:
The student dormitory management system plays an important role on the university campus. It can provide dormitory allocation, student information management, equipment borrowing and other functions. This article will introduce how to use Java language to implement a simple student dormitory management system.

1. System Requirements Analysis
The student dormitory management system needs to implement the following functions:

1. Student information management: including the entry, modification and query of basic student information.
2. Dormitory allocation: Allocate newly admitted students to appropriate dormitories to ensure that the number of residents in the dormitory is reasonable and the ratio of male and female students in the dormitory is balanced.
3. Equipment borrowing: Students can borrow equipment provided by the school, including computers, printers, etc., and need to record the borrowed equipment and return time.

2. System design

1. Student class(Student)

The student class contains basic information of students, such as student number, name, Gender, age, etc.

public class Student {
    private String studentNumber;
    private String name;
    private Gender gender;
    private int age;
    
    // 构造方法
    public Student(String studentNumber, String name, Gender gender, int age) {
        this.studentNumber = studentNumber;
        this.name = name;
        this.gender = gender;
        this.age = age;
    }
    
    // getter和setter方法
    // ...
}

2. Dormitory

The dormitory category contains basic information about the dormitory, such as dormitory number, floor, number of people who can live in it, etc.

public class Dormitory {
    private String dormitoryNumber;
    private int floor;
    private int capacity;
    private int currentOccupancy;
    
    // 构造方法
    public Dormitory(String dormitoryNumber, int floor, int capacity) {
        this.dormitoryNumber = dormitoryNumber;
        this.floor = floor;
        this.capacity = capacity;
        this.currentOccupancy = 0;
    }
    
    // getter和setter方法
    // ...
}

3. Student dormitory management system class (DormitoryManagementSystem)

The student dormitory management system class is the core class of the entire system, including the management functions of students and dormitories.

import java.util.ArrayList;
import java.util.List;

public class DormitoryManagementSystem {
    private List<Student> students;
    private List<Dormitory> dormitories;
    
    // 构造方法
    public DormitoryManagementSystem() {
        students = new ArrayList<>();
        dormitories = new ArrayList<>();
    }
    
    // 学生信息管理
    public void addStudent(Student student) {
        students.add(student);
    }
    
    public void updateStudent(Student student) {
        // 更新学生信息的逻辑
    }
    
    public Student queryStudent(String studentNumber) {
        // 查询学生信息的逻辑，并返回符合条件的学生对象
    }
    
    // 宿舍分配
    public void allocateDormitory(Student student) {
        // 分配宿舍的逻辑
    }
    
    // 设备借用
    public void borrowEquipment(Student student, String equipment) {
        // 设备借用的逻辑
    }
    
    public void returnEquipment(Student student, String equipment) {
        // 设备归还的逻辑
    }
}

3. System Implementation
Use Java language to implement the student dormitory management system, and you can use the command line or graphical interface for interaction. You can use Java's collection classes to manage students and dormitories, such as using ArrayList to store student and dormitory information.

public class Main {
    public static void main(String[] args) {
        DormitoryManagementSystem system = new DormitoryManagementSystem();
        
        // 添加学生
        
        // 查询学生信息
        
        // 宿舍分配
        
        // 设备借用和归还
        
        // ...
    }
}

4. Summary
This article introduces how to use Java language to implement a simple student dormitory management system. This system can help the school manage matters such as the allocation of student dormitories and equipment borrowing, and improve the efficiency of dormitory management. By learning and practicing this system, you can further understand the basic principles and methods of Java programming and improve your programming abilities.
