java做一个学生信息管理系统项目

学生信息管理系统可以分为三个模块，包括学生信息录入、学生信息查询和学生信息修改。下面是一个Java实现的学生信息管理系统项目的示例代码。

1. 学生信息类

public class Student {
    private int id; // 学生编号
    private String name; // 学生姓名
    private int age; // 学生年龄
    private String gender; // 学生性别
    private String phone; // 学生电话
    private String address; // 学生地址

    // 构造函数
    public Student(int id, String name, int age, String gender, String phone, String address) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.phone = phone;
        this.address = address;
    }

    // getter和setter方法
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

2. 学生信息录入模块

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

public class StudentManagement {
    private ArrayList<Student> students = new ArrayList<Student>(); // 存储学生信息

    // 添加学生信息
    public void addStudent() {
        Scanner input = new Scanner(System.in);
        System.out.println("请输入学生信息：");
        System.out.print("学生编号：");
        int id = input.nextInt();
        System.out.print("学生姓名：");
        String name = input.next();
        System.out.print("学生年龄：");
        int age = input.nextInt();
        System.out.print("学生性别：");
        String gender = input.next();
        System.out.print("学生电话：");
        String phone = input.next();
        System.out.print("学生地址：");
        String address = input.next();
        Student student = new Student(id, name, age, gender, phone, address);
        students.add(student);
        System.out.println("添加成功！");
    }

    // 显示学生信息
    public void showStudents() {
        if (students.isEmpty()) {
            System.out.println("没有学生信息！");
        } else {
            System.out.println("学生信息如下：");
            System.out.println("编号\t姓名\t年龄\t性别\t电话\t地址");
            for (Student student : students) {
                System.out.println(student.getId() + "\t" + student.getName() + "\t" + student.getAge() + "\t"
                        + student.getGender() + "\t" + student.getPhone() + "\t" + student.getAddress());
            }
        }
    }
}

3. 学生信息查询模块

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

public class StudentManagement {
    private ArrayList<Student> students = new ArrayList<Student>(); // 存储学生信息

    // 查询学生信息
    public void searchStudent() {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入要查询的学生编号：");
        int id = input.nextInt();
        boolean flag = false;
        for (Student student : students) {
            if (student.getId() == id) {
                flag = true;
                System.out.println("查询结果如下：");
                System.out.println("编号\t姓名\t年龄\t性别\t电话\t地址");
                System.out.println(student.getId() + "\t" + student.getName() + "\t" + student.getAge() + "\t"
                        + student.getGender() + "\t" + student.getPhone() + "\t" + student.getAddress());
                break;
            }
        }
        if (!flag) {
            System.out.println("没有找到该学生信息！");
        }
    }
}

4. 学生信息修改模块

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

public class StudentManagement {
    private ArrayList<Student> students = new ArrayList<Student>(); // 存储学生信息

    // 修改学生信息
    public void modifyStudent() {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入要修改的学生编号：");
        int id = input.nextInt();
        boolean flag = false;
        for (Student student : students) {
            if (student.getId() == id) {
                flag = true;
                System.out.println("请输入修改后的学生信息：");
                System.out.print("学生姓名：");
                String name = input.next();
                System.out.print("学生年龄：");
                int age = input.nextInt();
                System.out.print("学生性别：");
                String gender = input.next();
                System.out.print("学生电话：");
                String phone = input.next();
                System.out.print("学生地址：");
                String address = input.next();
                student.setName(name);
                student.setAge(age);
                student.setGender(gender);
                student.setPhone(phone);
                student.setAddress(address);
                System.out.println("修改成功！");
                break;
            }
        }
        if (!flag) {
            System.out.println("没有找到该学生信息！");
        }
    }
}

5. 主函数

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        StudentManagement sm = new StudentManagement();
        Scanner input = new Scanner(System.in);
        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1.添加学生信息");
            System.out.println("2.显示学生信息");
            System.out.println("3.查询学生信息");
            System.out.println("4.修改学生信息");
            System.out.println("0.退出");
            int choice = input.nextInt();
            switch (choice) {
                case 1:
                    sm.addStudent();
                    break;
                case 2:
                    sm.showStudents();
                    break;
                case 3:
                    sm.searchStudent();
                    break;
                case 4:
                    sm.modifyStudent();
                    break;
                case 0:
                    System.exit(0);
                    break;
                default:
                    System.out.println("输入错误，请重新输入！");
                    break;
            }
        }
    }
}

这个学生信息管理系统项目实现的功能包括学生信息录入、学生信息查询和学生信息修改。如果需要扩展功能，可以在此基础上进行修改和完善。
