Q1: 求一个用java写的学生成绩管理信息系统的源代码，要求有界面，能实现
以下方法实现了用户界面登陆
import java.awt.*;
import java.awt.event.*;
public class DengLuJieMian extends Frame implements ActionListener
{
Label username=new Label("用户名：");//使用文本创建一个用户名标签
TextField t1=new TextField();//创建一个文本框对象
Label password=new Label("密码：");//创建一个密码标签
TextField t2=new TextField();
Button b1=new Button("登陆");//创建登陆按钮
Button b2=new Button("取消");//创建取消按钮
public DengLuJieMian()
{
this.setTitle("学生信息管理系统");//设置窗口标题
this.setLayout(null);//设置窗口布局管理器
username.setBounds(50,40,60,20);//设置姓名标签的初始位置
this.add(username);// 将姓名标签组件添加到容器
t1.setBounds(120,40,80,20);// 设置文本框的初始位置
this.add(t1);// 将文本框组件添加到容器
password.setBounds(50,100,60,20);//密码标签的初始位置
this.add(password);//将密码标签组件添加到容器
t2.setBounds(120,100,80,20);//设置密码标签的初始位置
this.add(t2);//将密码标签组件添加到容器

this.add(b2);// 将取消按钮组件添加到容器
b1.addActionListener(this);//给登陆按钮添加监听器
b2.addActionListener(this);// 给取消按钮添加监听器
this.setVisible(true);//设置窗口的可见性
this.setSize(300,200);//设置窗口的大小
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});//通过内部类重写关闭窗体的方法
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==b1)//处理登陆事件
{
String name=t1.getText();
String pass=t2.getText();
if(name!=nullpass.equals("000123"))//判断语句
{
new StudentJieMian();
}
}
}
public static void main(String args[])//主函数
{
new DengLuJieMian();
}
}
以下方法实现了学生界面设计

public void windowClosing(WindowEvent e)
{
System.exit(0);//关闭窗口
}
});
}
public void actionPerformed(ActionEvent e)
{
