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.*; 
import java.awt.*; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 

public class MainUI extends JFrame implements ActionListener { 

 //定义组件 
 JButton jb1,jb2,jb3=null; 
 JRadioButton jrb1,jrb2=null; 
 JPanel jp1,jp2,jp3,jp4=null; 
 JTextField jtf=null; 
 JLabel jlb1,jlb2,jlb3=null; 
 JPasswordField jpf=null; 
 ButtonGroup bg=null; 

 //设定用户名和密码 
 final String stu_name="王小明"; 
 final String stu_pwd="1"; 
 final String stu_num="14140301"; 
 final String tea_name="王老师"; 
 final String tea_pwd="1"; 
 final String tea_num="00001"; 

 public static void main(String[] args) { 

  MainUI mUI=new MainUI(); 
 } 
 public MainUI() 
 { 
   //创建组件 
  jb1=new JButton("登录"); 
  jb2=new JButton("重置"); 
  jb3=new JButton("退出");

  //设置监听 
  jb1.addActionListener(this); 
  jb2.addActionListener(this); 
  jb3.addActionListener(this); 

  jrb1=new JRadioButton("教师"); 
  jrb2=new JRadioButton("学生"); 
  bg=new ButtonGroup(); 
  bg.add(jrb1); 
  bg.add(jrb2); 
  jrb2.setSelected(true); //初始页面默认选择权限为 学生

  jp1=new JPanel(); 
  jp2=new JPanel(); 
  jp3=new JPanel(); 
  jp4=new JPanel();     

  jlb1=new JLabel("用户名："); 
  jlb2=new JLabel("密 码："); 
  jlb3=new JLabel("权 限："); 

  jtf=new JTextField(10); 
  jpf=new JPasswordField(10); 
  //加入到JPanel中 
  jp1.add(jlb1); 
  jp1.add(jtf); 

  jp2.add(jlb2); 
  jp2.add(jpf); 

  jp3.add(jlb3);  //添加标签
  jp3.add(jrb1); 
  jp3.add(jrb2); 

  jp4.add(jb1);  //添加按钮
  jp4.add(jb2); 
  jp4.add(jb3);

  //加入JFrame中 
  this.add(jp1); 
  this.add(jp2); 
  this.add(jp3); 
  this.add(jp4); 

  this.setLayout(new GridLayout(4,1));   //选择GridLayout布局管理器  
  this.setTitle("学生成绩管理系统");   
  this.setSize(300,200);   
  this.setLocation(400, 200);   
  this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //设置当关闭窗口时，保证JVM也退出 
  this.setVisible(true); 
  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()) 
   { 
     tealogin();        //连接到教师的方法 页面
   }else if(jrb2.isSelected()) //学生在登录系统 
   { 
     stulogin();        //连接到学生的方法 页面
   } 

  }else if(e.getActionCommand()=="重置") 
  { 
     clear(); 
  }    

 } 

  //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);   
   dispose();  
   clear();   
   StdUI ui=new StdUI();  //创建新界面 
  }else if(jtf.getText().isEmpty()&&jpf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入用户名和密码！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else if(jtf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入用户名！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else if(jpf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入密码！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else 
  { 
   JOptionPane.showMessageDialog(null,"用户名或者密码错误！\n请重新输入","提示消息",JOptionPane.ERROR_MESSAGE); 
   //清空输入框 
   clear(); 
  } 
 } 
 //教师登录判断方法 
 public void tealogin() 
 { 
  if(tea_name.equals(jtf.getText())&&tea_pwd.equals(jpf.getText())) 
  { 

    JOptionPane.showMessageDialog(null,"登录成功！","提示消息",JOptionPane.WARNING_MESSAGE); 
    clear();   
    dispose();    
    TerUI ui=new TerUI(); //创建一个新界面 
  }else if(jtf.getText().isEmpty()&&jpf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入用户名和密码！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else if(jtf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入用户名！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else if(jpf.getText().isEmpty()) 
  { 
   JOptionPane.showMessageDialog(null,"请输入密码！","提示消息",JOptionPane.WARNING_MESSAGE); 
  }else 
  { 
   JOptionPane.showMessageDialog(null,"用户名或者密码错误！\n请重新输入","提示消息",JOptionPane.ERROR_MESSAGE); 
   clear(); //清空输入框 
  } 
 } 
 //清空文本框和密码框 
 public void clear() 
 { 
  jtf.setText(""); 
  jpf.setText(""); 
 } 

}

运行图1

用户名和密码如下：

用户名和密码

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。

学生页面

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。

学生页面

4.完成学生界面的课程表界面（代码如下）

6.完成教师的课程管理界面（代码如下）
