宿舍管理系统代码

由于宿舍管理系统较为复杂，涉及多个模块和功能，因此无法提供完整的代码。但是，我可以提供一些常用的Java类和方法，供您参考。

1. 学生信息类（Student）：

public class Student {
    private String name;
    private String id;
    private String gender;
    private String dormNumber;

    public Student(String name, String id, String gender) {
        this.name = name;
        this.id = id;
        this.gender = gender;
    }

    public String getName() {
        return name;
    }

    public String getId() {
        return id;
    }

    public String getGender() {
        return gender;
    }

    public String getDormNumber() {
        return dormNumber;
    }

    public void setDormNumber(String dormNumber) {
        this.dormNumber = dormNumber;
    }
}

2. 宿舍信息类（Dorm）：

public class Dorm {
    private String dormNumber;
    private int capacity;
    private int currentOccupancy;
    private List<Student> students;

    public Dorm(String dormNumber, int capacity) {
        this.dormNumber = dormNumber;
        this.capacity = capacity;
        this.currentOccupancy = 0;
        this.students = new ArrayList<>();
    }

    public String getDormNumber() {
        return dormNumber;
    }

    public int getCapacity() {
        return capacity;
    }

    public int getCurrentOccupancy() {
        return currentOccupancy;
    }

    public List<Student> getStudents() {
        return students;
    }

    public void addStudent(Student student) {
        if (currentOccupancy < capacity) {
            students.add(student);
            currentOccupancy++;
            student.setDormNumber(dormNumber);
            System.out.println("Student " + student.getName() + " has been assigned to dorm " + dormNumber);
        } else {
            System.out.println("Dorm " + dormNumber + " is already full");
        }
    }

    public void removeStudent(Student student) {
        students.remove(student);
        currentOccupancy--;
        student.setDormNumber(null);
        System.out.println("Student " + student.getName() + " has been removed from dorm " + dormNumber);
    }
}

3. 宿舍管理系统类（DormitoryManagementSystem）：

public class DormitoryManagementSystem {
    private List<Student> students;
    private List<Dorm> dorms;

    public DormitoryManagementSystem() {
        this.students = new ArrayList<>();
        this.dorms = new ArrayList<>();
    }

    public void addStudent(Student student) {
        students.add(student);
    }

    public void addDorm(Dorm dorm) {
        dorms.add(dorm);
    }

    public void assignDorm(Student student) {
        for (Dorm dorm : dorms) {
            if (dorm.getCurrentOccupancy() < dorm.getCapacity()) {
                dorm.addStudent(student);
                break;
            }
        }
    }

    public void removeStudentFromDorm(Student student) {
        for (Dorm dorm : dorms) {
            if (dorm.getStudents().contains(student)) {
                dorm.removeStudent(student);
                break;
            }
        }
    }
}

以上是部分代码示例，可以根据具体需求进行改进和完善。
