Java GUI製作簡單的管理系統

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); //添加標籤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佈局管理器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(""); } }

運行圖1

用戶名和密碼如下：

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); //設置佈局管理器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後面步驟。

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)); //設置佈局管理器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後面步驟。

4.完成學生界面的課程表界面（代碼如下）
