這篇文章主要為大家展示了“Java GUI如何制作管理系統”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“Java GUI如何制作管理系統”這篇文章吧。
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("");
}
}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。
