⑸ Java程序设计课程设计 学生信息管理系统 要求：使用图形用户界面用数据库建立1或
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!=null&&pass.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 }
