Java GUI制作简单的管理系统

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：

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）
