BufferedReader br = new BufferedReader(new FileReader("D:\student.txt"));

String tmpStr = br.readLine();

while(tmpStr != null){

int firstIndex = tmpStr.indexOf(" ");

int secondIndex = tmpStr.indexOf(" ",firstIndex + 1);

int thirdIndex = tmpStr.indexOf(" ", secondIndex + 1);

int forthIndex = tmpStr.indexOf(" ", thirdIndex + 1);

Student student = new Student();

student.setStuId(stuId);

student.setStuName(stuName);

student.setStuYW(stuYW);

student.setStuSX(stuSX);

student.setStuYY(stuYY);

students.add(student);

tmpStr.readLine();

}

//创建一个学生实体类 封装stuId stuName stuYW stuSx stuYY 这5个属性。。。

//已经帮你把数据拆分出来 并以Student 对象的形式放入集合中了 接下来 给分吧 哇咔咔

求用Java编写的学生成绩管理系统的完整代码，要能运行的

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

b1.setBounds(50,150,60,20);//设置登陆按钮的初始位置

this.add(b1);//将登陆按钮组件添加到容器

b2.setBounds(120,150,60,20);//设置取消按钮的初始位置

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

import java.awt.*;

import java.awt.event.*;

class StudentJieMian extends Frame implements ActionListener

{

MenuBar m=new MenuBar();//创建菜单栏

Menu m1=new Menu("信息");//创建菜单“信息”

MenuItem m11=new MenuItem("插入");//创建“插入”的菜单项

MenuItem m12=new MenuItem("查询");

Menu m2=new Menu("成绩");//创建菜单“成绩”

MenuItem m21=new MenuItem("查询");

public StudentJieMian()

{

this.setTitle("学生界面");//设置窗口标题

this.setLayout(new CardLayout());//设置窗口布局管理器

this.setMenuBar(m);//将菜单栏组件添加到容器

m.add(m1);//将信息菜单放入菜单栏

m.add(m2);

m1.add(m11);//将“插入”菜单项添加到“信息”菜单

m1.add(m12); //将“查询”菜单项添加到“信息”菜单

m2.add(m21); //将“查询”菜单项添加到“成绩”菜单

m11.addActionListener(this); //给“插入”菜单项添加监听器

m12.addActionListener(this); //给“查询”菜单项添加监听器

m21.addActionListener(this); //给“查询”菜单项添加监听器

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);//关闭窗口

}

});

}

public void actionPerformed(ActionEvent e)

{

if(e.getSource()==m11) //处理“添加信息”事件

{

new AddStudent();

}

if(e.getSource()==m12) //处理“查询信息”事件

{

new SelectStudent();

}

if(e.getSource()==m21) //处理“查询成绩”事件

{

new ChengJiStudent();

}

}

public static void main(String args[])

{ new StudentJieMian(); //创建一个对象 }
