用java设计一个学生信息管理界面 学生信息有：学号（要求唯一）、姓名、性别（录入时用单选按钮选择）、出生日期（用日期时间控件录入）、专业（用组合框选择录入）、照片。录入功能：按照上述要求将若干个学生的信息存储到数组；浏览功能：利用列表框显示所有已录入学生的信息（注意显示效果的美观）；查询功能：可以分别按照学号、性别、专业查询，并将查询结果显示在列表框中。（提示：定义学生信息结构体或类，将学生信息数组定义为窗体类的成员）。要求系统的使用要进行身份验证，即在开始显示主界面之前，先显示登录窗口，进行用户名和密码的检验，只有通过验证的才能看到主界面，否则3次机会后程序结束不允许使用该系统。

好的，根据您的需求，我可以为您提供一个简单的学生信息管理界面的Java代码实现，代码如下：

import java.awt.event.ActionListener;
import java.util.ArrayList;

        this.id = id;
        this.name = name;
        this.gender = gender;
        this.birthday = birthday;
        this.major = major;

这个程序实现了身份验证功能，输入正确的用户名和密码才能进入主界面。主界面上有一个输入面板，用于录入学生信息，包括学号、姓名、性别、出生日期、专业和照片。录入完成后，用户可以点击“Add”按钮将学生信息保存到数组中。用户还可以点击“Browse”按钮查看已保存的所有学生信息。如果需要查询学生信息，用户可以点击“Search”按钮，输入查询类型（学号、性别或专业）和相应的查询条件，查询结果将在右侧的列表框中显示出来。
