⑸ Java程序設計課程設計 學生信息管理系統 要求：使用圖形用戶界面用資料庫建立1或
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
{
new DengLuJieMian();
}
}
以下方法實現了學生界面設計
import java.awt.*;
import java.awt.event.*;
class StudentJieMian extends Frame implements ActionListener
{
MenuBar m=new MenuBar();//創建菜單欄
Menu m1=new Menu("信息");//創建菜單「信息」
MenuItem m11=new MenuItem("插入");//創建「插入」的菜單項
MenuItem m12=new MenuItem("查詢");
Menu m2=new Menu("成績");//創建菜單「成績」
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);
m1.add(m11);//將「插入」菜單項添加到「信息」菜單
m1.add(m12); //將「查詢」菜單項添加到「信息」菜單
m2.add(m21); //將「查詢」菜單項添加到「成績」菜單
m11.addActionListener(this); //給「插入」菜單項添加監聽器
m12.addActionListener(this); //給「查詢」菜單項添加監聽器
m21.addActionListener(this); //給「查詢」菜單項添加監聽器
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);//關閉窗口
}
});
}
public void actionPerformed(ActionEvent e)
{
if(e.getSource()==m11) //處理「添加信息」事件
{
new AddStudent();
}
if(e.getSource()==m12) //處理「查詢信息」事件
{
new SelectStudent();
}
if(e.getSource()==m21) //處理「查詢成績」事件
{
new ChengJiStudent();
}
}
public static void main(String args[])
{ new StudentJieMian(); //創建一個對象 }
