public class mainui extends jframe implements actionlistener {

}
public mainui()
{
//创建组件

jp4.add(jb3);
//加入jframe中
this.add(jp1);

}
}else if(e.getactioncommand()=="重置")
{

}
}
//学生登录判断方法
public void stulogin()
{
if(stu_name.equals(jtf.gettext())&&stu_pwd.equals(jpf.gettext()))
{
joptionpane.showmessagedialog(null,"登录成功！","提示消息",joptionpane.warning_message);

{
jtf.settext("");

}
}
运行图1
用户名和密码如下：
2.完成学生界面stuui，这个页面在mainui界面设置了按钮连接（代码如下）
package com.pag_1;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.jbutton;
import java.awt.color.*;
import javax.swing.joptionpane;
import com.pag_1.mainui;
public class stdui extends jframe implements actionlistener
{
//定义组件
jbutton jb1=new jbutton();
jbutton jb2=new jbutton();
jpanel jp1,jp2,jp3,jp4=null;
jlabel jlb1,jlb2,jlb3,jlb4,jlb5,jlb6=null;
public static void main(string[] args)
{
stdui ui=new stdui();
}
//****************************事件判断**********************
//构造函数
public stdui() //不能申明为void!!!!!否则弹不出新界面
{
//创建组件
jb1=new jbutton("课程表");
jb1.setforeground(color.blue);
jb2=new jbutton("成绩查询");
jb2.setforeground(color.blue);
jp1=new jpanel();
jp2=new jpanel();
jp3=new jpanel();
jlb1=new jlabel("姓名：");
jlb2=new jlabel("学号：");
jlb3=new jlabel("最新公告：");
jlb3.setforeground(color.red);
jlb4=new jlabel("我院举行学生体测通知");
jlb5=new jlabel(new mainui().stu_name);
jlb6=new jlabel(new mainui().stu_num);
jp1.add(jlb1);
jp1.add(jlb5);
jp1.add(jlb2);
jp1.add(jlb6);
jp2.add(jb1);
jp2.add(jb2);
jp3.add(jlb3);
jp3.add(jlb4);
this.add(jp1);
this.add(jp2);
this.add(jp3);
//设置布局管理器
this.setlayout(new gridlayout(4,3,50,50));
this.settitle("学生成绩管理系统");
this.setsize(400,300);
this.setlocation(200, 200);
this.setdefaultcloseoperation(jframe.exit_on_close);
this.setvisible(true);
jb1.addactionlistener(this);
jb2.addactionlistener(this);
}
public void actionperformed(actionevent e) {
if(e.getsource() == jb1){
//关闭当前界面
dispose();
new kechengbiaoui();
}else if(e.getsource() == jb2){
//关闭当前界面
dispose();
new chengjibiaoui();
}
}
}
运行mainui输入用户学生，会出现下面学生界面，其中界面中的 课程表和成绩查询是两个可以点击的按钮，会连接到下个页面再后面步骤。
3.完成教师界面terui，这个和学生页面一样，在mainui页面有设置按钮事件，连接到mainui页面.(代码如下)
package com.pag_1;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.jbutton;
import com.pag_1.mainui;
public class terui extends jframe implements actionlistener
{
//定义组件
jbutton jb1,jb2=null;
jpanel jp1,jp2,jp3,jp4=null;
jlabel jlb1,jlb2,jlb3,jlb4,jlb5,jlb6=null;
public static void main(string[] args) {
terui ui=new terui();
}
public terui()
{
//创建组件
jb1=new jbutton("课程管理");
jb1.setforeground(color.blue);
jb2=new jbutton("学生名单");
jb2.setforeground(color.blue);
jp1=new jpanel();
jp2=new jpanel();
jp3=new jpanel();
jlb1=new jlabel("姓名：");
jlb2=new jlabel("工号：");
jlb3=new jlabel("最新公告：");
jlb3.setforeground(color.red);
jlb4=new jlabel("我院举行体测的通知");
jlb5=new jlabel(new mainui().tea_name);
jlb6=new jlabel(new mainui().tea_num);
jp1.add(jlb1);
jp1.add(jlb5);
jp1.add(jlb2);
jp1.add(jlb6);
jp2.add(jb1);
jp2.add(jb2);
jp3.add(jlb3);
jp3.add(jlb4);
this.add(jp1);
this.add(jp2);
this.add(jp3);
this.setlayout(new gridlayout(4,3,50,50)); //设置布局管理器
this.settitle("学生成绩管理系统");
this.setsize(400,300);
this.setlocation(200, 200);
this.setdefaultcloseoperation(jframe.exit_on_close);
this.setvisible(true);
jb1.addactionlistener(this);
jb2.addactionlistener(this);
}
public void actionperformed(actionevent e) {
if(e.getsource() == jb1){
dispose();
new kechengguanliui(); //创建一个新界面
}else if(e.getsource() == jb2){
dispose();
new xueshengmingdanui(); //创建一个新界面
}
}
}
运行mainui输入用户教师，会出现下面教师界面，其中界面中的 课程管理和学生名单是两个可以点击的按钮，会连接到下个页面再后面步骤。
4.完成学生界面的课程表界面（代码如下）
