java学生信息管理系统

一个基本的 Java 学生信息管理系统应该包含以下功能：

1. 添加学生信息：包括学生的姓名、学号、性别、年龄、出生日期、籍贯、专业等信息；
2. 查询学生信息：可以通过学号、姓名等条件查询学生信息；
3. 修改学生信息：可以修改学生的各项信息；
4. 删除学生信息：可以根据学号删除学生信息；
5. 展示学生信息：将所有学生信息展示出来，包括姓名、学号、性别、年龄、出生日期、籍贯、专业等信息。

下面是一个简单的示例代码，可以作为学生信息管理系统的基础框架：

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

public class Student {
    private String name;
    private String id;
    private String gender;
    private int age;

        this.gender = gender;
        this.age = age;
        this.birthDate = birthDate;
        this.hometown = hometown;

    }

    public String getName() {
