本文实例为大家分享了java gui管理系统的具体代码,供大家参考,具体内容如下

1.先完成主页面mainui(代码如下)

package com.pag_1; 
import javax.swing.*;

  this.setresizable(true); 

 } 

 public void actionperformed(actionevent e) {   //事件判断

  if(e.getactioncommand()=="登录") 
  { 
   //如果选中教师登录 
   if(jrb1.isselected())

  jtf.settext(""); 
  jpf.settext(""); 
 } 

}

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。
