本文實例為大家分享了Java GUI管理系統的具體代碼，供大家參考，具體內容如下

1.先完成主頁面MainUI（代碼如下）

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 {  //定義組件  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;  //設定用戶名和密碼  final String stu_name="王小明";  final String stu_pwd="1";  final String stu_num="14140301";  final String tea_name="王老師";  final String tea_pwd="1";  final String tea_num="00001";  public static void main(String[] args) {   MainUI mUI=new MainUI();  }  public MainUI()  {    //創建組件   jb1=new JButton("登錄");   jb2=new JButton("重置");   jb3=new JButton("退出");  //設置監聽   jb1.addActionListener(this);   jb2.addActionListener(this);   jb3.addActionListener(this);   jrb1=new JRadioButton("教師");   jrb2=new JRadioButton("學生");   bg=new ButtonGroup();   bg.add(jrb1);   bg.add(jrb2);   jrb2.setSelected(true); //初始頁面默認選擇權限為 學生  jp1=new JPanel();   jp2=new JPanel();   jp3=new JPanel();   jp4=new JPanel();       jlb1=new JLabel("用戶名：");   jlb2=new JLabel("密 碼：");   jlb3=new JLabel("權 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);  //添加標簽  jp3.add(jrb1);   jp3.add(jrb2);   jp4.add(jb1);  //添加按鈕  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));   //選擇GridLayout布局管理器    this.setTitle("學生成績管理系統");     this.setSize(300,200);     this.setLocation(400, 200);     this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //設置當關閉窗口時，保證JVM也退出   this.setVisible(true);   this.setResizable(true);  }  public void actionPerformed(ActionEvent e) {   //事件判斷  if(e.getActionCommand()=="登錄")   {    //如果選中教師登錄    if(jrb1.isSelected())    {      tealogin();        //連接到教師的方法 頁面   }else if(jrb2.isSelected()) //學生在登錄系統    {      stulogin();        //連接到學生的方法 頁面   }   }else if(e.getActionCommand()=="重置")   {      clear();   }     }   //學生登錄判斷方法  public void stulogin()  {   if(stu_name.equals(jtf.getText())&&stu_pwd.equals(jpf.getText()))   {      JOptionPane.showMessageDialog(null,"登錄成功！","提示消息",JOptionPane.WARNING_MESSAGE);      dispose();     clear();      StdUI ui=new StdUI();  //創建新界面   }else if(jtf.getText().isEmpty()&&jpf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入用戶名和密碼！","提示消息",JOptionPane.WARNING_MESSAGE);   }else if(jtf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入用戶名！","提示消息",JOptionPane.WARNING_MESSAGE);   }else if(jpf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入密碼！","提示消息",JOptionPane.WARNING_MESSAGE);   }else   {    JOptionPane.showMessageDialog(null,"用戶名或者密碼錯誤！/n請重新輸入","提示消息",JOptionPane.ERROR_MESSAGE);    //清空輸入框    clear();   }  }  //教師登錄判斷方法  public void tealogin()  {   if(tea_name.equals(jtf.getText())&&tea_pwd.equals(jpf.getText()))   {     JOptionPane.showMessageDialog(null,"登錄成功！","提示消息",JOptionPane.WARNING_MESSAGE);     clear();       dispose();        TerUI ui=new TerUI(); //創建一個新界面   }else if(jtf.getText().isEmpty()&&jpf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入用戶名和密碼！","提示消息",JOptionPane.WARNING_MESSAGE);   }else if(jtf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入用戶名！","提示消息",JOptionPane.WARNING_MESSAGE);   }else if(jpf.getText().isEmpty())   {    JOptionPane.showMessageDialog(null,"請輸入密碼！","提示消息",JOptionPane.WARNING_MESSAGE);   }else   {    JOptionPane.showMessageDialog(null,"用戶名或者密碼錯誤！/n請重新輸入","提示消息",JOptionPane.ERROR_MESSAGE);    clear(); //清空輸入框   }  }  //清空文本框和密碼框  public void clear()  {   jtf.setText("");   jpf.setText("");  } }

2.完成學生界面StuUI，這個頁面在MainUI界面設置了按鈕連接（代碼如下）

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 {    //定義組件   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();   }   //****************************事件判斷**********************  //構造函數   public StdUI() //不能申明為void!!!!!否則彈不出新界面   {    //創建組件    jb1=new JButton("課程表");    jb1.setForeground(Color.BLUE);   jb2=new JButton("成績查詢");    jb2.setForeground(Color.BLUE);   jp1=new JPanel();    jp2=new JPanel();    jp3=new JPanel();    jlb1=new JLabel("姓名：");    jlb2=new JLabel("學號：");    jlb3=new JLabel("最新公告：");    jlb3.setForeground(Color.red);   jlb4=new JLabel("我院舉行學生體測通知");    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);    //設置布局管理器    this.setLayout(new GridLayout(4,3,50,50));    this.setTitle("學生成績管理系統");    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){    //關閉當前界面      dispose();      new KeChengBiaoUI();    }else if(e.getSource() == jb2){     //關閉當前界面      dispose();      new ChengJiBiaoUI();    }  } }

運行MainUI輸入用戶學生，會出現下面學生界面，其中界面中的課程表和成績查詢是兩個可以點擊的按鈕，會連接到下個頁面再后面步驟。

3.完成教師界面TerUI，這個和學生頁面一樣，在MainUI頁面有設置按鈕事件，連接到MainUI頁面.(代碼如下)

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 {    //定義組件   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()   {    //創建組件    jb1=new JButton("課程管理");   jb1.setForeground(Color.BLUE);   jb2=new JButton("學生名單");    jb2.setForeground(Color.BLUE);   jp1=new JPanel();    jp2=new JPanel();    jp3=new JPanel();    jlb1=new JLabel("姓名：");    jlb2=new JLabel("工號：");    jlb3=new JLabel("最新公告：");    jlb3.setForeground(Color.red);   jlb4=new JLabel("我院舉行體測的通知");    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)); //設置布局管理器    this.setTitle("學生成績管理系統");    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();    //創建一個新界面     }else if(e.getSource() == jb2){     dispose();      new XueShengMingDanUI();    //創建一個新界面     }  } }

運行MainUI輸入用戶教師，會出現下面教師界面，其中界面中的課程管理和學生名單是兩個可以點擊的按鈕，會連接到下個頁面再后面步驟。
