『貳』 誰有java實現的學生信息管理系統源碼
可以試試看啊
以下方法實現了用戶界面登陸
import java.awt.*;
import java.awt.event.*;
public class DengLuJieMian extends Frame implements ActionListener
{
Label username=new Label("用戶名：");//使用文本創建一個用戶名標簽
TextField t1=new TextField();//創建一個文本框對象
Label password=new Label("密碼：");//創建一個密碼標簽
TextField t2=new TextField();
Button b1=new Button("登陸");//創建登陸按鈕
Button b2=new Button("取消");//創建取消按鈕
public DengLuJieMian()
{
this.setTitle("學生信息管理系統");//設置窗口標題
this.setLayout(null);//設置窗口布局管理器
username.setBounds(50,40,60,20);//設置姓名標簽的初始位置
this.add(username);// 將姓名標簽組件添加到容器
t1.setBounds(120,40,80,20);// 設置文本框的初始位置
this.add(t1);// 將文本框組件添加到容器
password.setBounds(50,100,60,20);//密碼標簽的初始位置
this.add(password);//將密碼標簽組件添加到容器
t2.setBounds(120,100,80,20);//設置密碼標簽的初始位置
this.add(t2);//將密碼標簽組件添加到容器
b1.setBounds(50,150,60,20);//設置登陸按鈕的初始位置
this.add(b1);//將登陸按鈕組件添加到容器
b2.setBounds(120,150,60,20);//設置取消按鈕的初始位置
this.add(b2);// 將取消按鈕組件添加到容器
b1.addActionListener(this);//給登陸按鈕添加監聽器
b2.addActionListener(this);// 給取消按鈕添加監聽器
this.setVisible(true);//設置窗口的可見性
this.setSize(300,200);//設置窗口的大小
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});//通過內部類重寫關閉窗體的方法
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==b1)//處理登陸事件
{
String name=t1.getText();
String pass=t2.getText();
if(name!=null&&pass.equals("000123"))//判斷語句
{
new StudentJieMian();
}
}
}
public static void main(String args[])//主函數
{

以下方法實現了學生界面設計

MenuItem m21=new MenuItem("查詢");
public StudentJieMian()
{
this.setTitle("學生界面");//設置窗口標題
this.setLayout(new CardLayout());//設置窗口布局管理器
this.setMenuBar(m);//將菜單欄組件添加到容器
m.add(m1);//將信息菜單放入菜單欄
m.add(m2);

『叄』 求C++圖書信息管理系統設計源代碼
你在這發 別人是不可能給你敲出來的
其實這種系統 網上的源碼太多了 你可以網路一下 然後自己修改一下 也鍛煉了自己的能力了
網路文庫的：http://wenku..com/view/88a74f0d844769eae009ed73.html
http://wenku..com/view/d59d8484b9d528ea81c779d3.html

『陸』 學生信息管理系統最簡單源代碼。
方法一：
1、創建一個c語言項目。然後右鍵頭文件，創建一個Stu的頭文件。
『柒』 分地區查詢系統源碼
都快畢業了還不自己好好想想啊！
『捌』 求一個用java寫的學生成績管理信息系統的源代碼，要求有界面，能實現
以下方法實現了用戶界面登陸
import java.awt.*;
import java.awt.event.*;
public class DengLuJieMian extends Frame implements ActionListener
{
Label username=new Label("用戶名：");//使用文本創建一個用戶名標簽
TextField t1=new TextField();//創建一個文本框對象
Label password=new Label("密碼：");//創建一個密碼標簽
TextField t2=new TextField();
Button b1=new Button("登陸");//創建登陸按鈕
Button b2=new Button("取消");//創建取消按鈕
public DengLuJieMian()
{
this.setTitle("學生信息管理系統");//設置窗口標題
this.setLayout(null);//設置窗口布局管理器
username.setBounds(50,40,60,20);//設置姓名標簽的初始位置
this.add(username);// 將姓名標簽組件添加到容器
t1.setBounds(120,40,80,20);// 設置文本框的初始位置
this.add(t1);// 將文本框組件添加到容器
password.setBounds(50,100,60,20);//密碼標簽的初始位置
this.add(password);//將密碼標簽組件添加到容器
t2.setBounds(120,100,80,20);//設置密碼標簽的初始位置
this.add(t2);//將密碼標簽組件添加到容器
b1.setBounds(50,150,60,20);//設置登陸按鈕的初始位置
this.add(b1);//將登陸按鈕組件添加到容器
b2.setBounds(120,150,60,20);//設置取消按鈕的初始位置
this.add(b2);// 將取消按鈕組件添加到容器
b1.addActionListener(this);//給登陸按鈕添加監聽器
b2.addActionListener(this);// 給取消按鈕添加監聽器
this.setVisible(true);//設置窗口的可見性
this.setSize(300,200);//設置窗口的大小
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});//通過內部類重寫關閉窗體的方法
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==b1)//處理登陸事件
{
String name=t1.getText();
String pass=t2.getText();
if(name!=null&&pass.equals("000123"))//判斷語句
{
new StudentJieMian();
}
}
}
public static void main(String args[])//主函數

}
}
以下方法實現了學生界面設計

{
this.setTitle("學生界面");//設置窗口標題
this.setLayout(new CardLayout());//設置窗口布局管理器
this.setMenuBar(m);//將菜單欄組件添加到容器
m.add(m1);//將信息菜單放入菜單欄
