Java?GUI實現(xiàn)學生成績管理系統(tǒng)

更新時間：2024年06月13日 14:38:39 作者：只要你能好

這篇文章主要為大家詳細介紹了Java?GUI實現(xiàn)學生成績管理系統(tǒng)，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

學習java有一年多了，一直在做web方面的練習，在一個項目中發(fā)現(xiàn)需要用到GUI的相關知識，結果沒法做出來，網(wǎng)上這方面的文章又不是很多，所有只好自己硬著頭皮從頭再學一遍了，不過學習后發(fā)現(xiàn)，其實GUI是非常有趣的，他并不像WEB程序一樣依賴互聯(lián)網(wǎng)，而且還有許多布局和android相差不是很大，這才發(fā)現(xiàn)自己竟又愛上GUI的開發(fā)了，不多說了，直接上代碼吧，相信有過android或相關界面開發(fā)的都明白這其中的道理。

先看看效果吧

1.登錄主界面

package edu.gzu.stuManager; 
 
import java.awt.EventQueue; 
 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JOptionPane; 
 
import java.awt.Toolkit; 
 
import javax.swing.JTextField; 
 
import edu.gzu.stuManager.Dao.UserLoginValid; 
import edu.gzu.stuManager.Domain.StudentInfo; 
import edu.gzu.stuManager.View.StudentMainView; 
 
import java.awt.Choice; 
import java.awt.Font; 
import java.awt.Button; 
import java.awt.event.MouseAdapter; 
import java.awt.event.MouseEvent; 
 
public class MainUI { 
 
 private JFrame frame; 
 private JTextField textField; 
 private JTextField textField_1; 
 
 /** 
 * Launch the application. 
 */ 
 public static void main(String[] args) { 
 EventQueue.invokeLater(new Runnable() { 
 public void run() { 
 try { 
  MainUI window = new MainUI(); 
  window.frame.setVisible(true); 
 } catch (Exception e) { 
  e.printStackTrace(); 
 } 
 } 
 }); 
 } 
 
 /** 
 * Create the application. 
 */ 
 public MainUI() { 
 initialize(); 
 } 
 
 /** 
 * Initialize the contents of the frame. 
 */ 
 private void initialize() { 
 frame = new JFrame(); 
 frame.setTitle("\u6210\u7EE9\u7BA1\u7406\u7CFB\u7EDF\uFF08\u767B\u5F55\uFF09"); 
 frame.setIconImage(Toolkit.getDefaultToolkit().getImage(MainUI.class.getResource("/image/func_list7_privmana.png"))); 
 frame.setBounds(400, 250, 450, 300); 
 frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
 frame.getContentPane().setLayout(null); 
 
 JLabel lblNewLabel = new JLabel("\u5B66\u751F\u6210\u7EE9\u7BA1\u7406\u7CFB\u7EDF\u7528\u6237\u767B\u5F55\uFF01"); 
 lblNewLabel.setFont(new Font("宋體", Font.PLAIN, 16)); 
 lblNewLabel.setBounds(111, 17, 287, 15); 
 frame.getContentPane().add(lblNewLabel); 
 
 JLabel lblNewLabel_1 = new JLabel("\u7528\u6237\u540D\uFF1A"); 
 lblNewLabel_1.setFont(new Font("宋體", Font.PLAIN, 14)); 
 lblNewLabel_1.setBounds(87, 67, 67, 15); 
 frame.getContentPane().add(lblNewLabel_1); 
 
 textField = new JTextField(); 
 textField.setBounds(154, 64, 141, 21); 
 frame.getContentPane().add(textField); 
 textField.setColumns(10); 
 
 JLabel label = new JLabel("\u5BC6 \u7801\uFF1A"); 
 label.setFont(new Font("宋體", Font.PLAIN, 14)); 
 label.setBounds(87, 108, 67, 15); 
 frame.getContentPane().add(label); 
 
 textField_1 = new JTextField(); 
 textField_1.setColumns(10); 
 textField_1.setBounds(154, 103, 141, 21); 
 frame.getContentPane().add(textField_1); 
 
 JLabel lblNewLabel_2 = new JLabel("\u6211\u7684\u8EAB\u4EFD\u662F\uFF1A"); 
 lblNewLabel_2.setFont(new Font("宋體", Font.PLAIN, 14)); 
 lblNewLabel_2.setBounds(105, 150, 97, 15); 
 frame.getContentPane().add(lblNewLabel_2); 
 
 final Choice choice = new Choice(); 
 choice.setBounds(210, 147, 74, 21); 
 choice.add("學生"); 
 choice.add("教師"); 
 choice.add("系統(tǒng)管理員"); 
 frame.getContentPane().add(choice); 
 
 Button button = new Button("\u767B\u5F55"); 
 button.setBounds(87, 194, 76, 23); 
 button.addMouseListener(new MouseAdapter() { 
 @Override 
 public void mouseClicked(MouseEvent e) { 
 String user=textField.getText(); 
 String password=textField_1.getText(); 
 String shenfen=choice.getSelectedItem(); 
 if(user.equals("")||user==null){ 
  JOptionPane.showMessageDialog(frame, shenfen+":您好，帳號不能為空！"); 
  return; 
 }else if(password.equals("")||password==null){ 
  JOptionPane.showMessageDialog(frame, shenfen+":您好，密碼不能為空！"); 
  return; 
 }else{ 
  StudentInfo stu=new StudentInfo(Integer.parseInt(user), 
  Integer.parseInt(password),shenfen); 
  UserLoginValid dao=new UserLoginValid(); 
  String result=dao.isValid(stu); 
  
  if("登錄成功！".equals(result)){ 
  JOptionPane.showMessageDialog(frame,result); 
  StudentMainView index=new StudentMainView(stu); 
  JFrame frame2=index.getFrame(); 
  frame2.setVisible(true); 
  frame.dispose(); 
  }else{ 
  JOptionPane.showMessageDialog(frame,result); 
  } 
  
 } 
 } 
 }); 
 frame.getContentPane().add(button); 
 
 Button button_1 = new Button("\u53D6\u6D88"); 
 button_1.setBounds(219, 194, 76, 23); 
 frame.getContentPane().add(button_1); 
 
 
 } 
 
}

2.登錄驗證邏輯

package edu.gzu.stuManager.Dao; 
 
import edu.gzu.stuManager.Domain.StudentInfo; 
 
public class UserLoginValid { 
 
 public String isValid(StudentInfo stu){ 
 int idnum=stu.getIdnum(); 
 int password=stu.getPassword(); 
 String idntify=stu.getIdentify(); 
 String result=null; 
 
 if("學生".equals(idntify)){ 
 if(idnum==1207010209&&password==123){ 
 stu.setName("劉明勝 同學"); 
 result="登錄成功！"; 
 }else{ 
 result="學生帳號中不存在此用戶，請確認身份后再次登錄！"; 
 } 
 }else if("教師".equals(idntify)){ 
 if(idnum==1174386356&&password==123){ 
 stu.setName("劉明勝 老師"); 
 result="登錄成功！"; 
 }else{ 
 result="教師帳號中不存在此用戶，請確認身份后再次登錄！"; 
 } 
 }else if("系統(tǒng)管理員".equals(idntify)){ 
 if(idnum==999999&&password==123){ 
 stu.setName("系統(tǒng)管理員"); 
 result="登錄成功！"; 
 }else{ 
 result="系統(tǒng)管理員帳號中不存在此用戶，請確認身份后再次登錄！"; 
 } 
 } 
 
 
 return result; 
 } 
}

3.用戶對象（這是一個簡單bean）

package edu.gzu.stuManager.Domain; 
 
public class StudentInfo { 
 private int idnum; 
 private String name; 
 private int password; 
 private String identify; 
 
 public StudentInfo(int idnum,int password, String identify) { 
 super(); 
 this.idnum = idnum; 
 this.password = password; 
 this.identify = identify; 
 } 
 public int getIdnum() { 
 return idnum; 
 } 
 public void setIdnum(int idnum) { 
 this.idnum = idnum; 
 } 
 public String getName() { 
 return name; 
 } 
 public void setName(String name) { 
 this.name = name; 
 } 
 public int getPassword() { 
 return password; 
 } 
 public void setPassword(int password) { 
 this.password = password; 
 } 
 public String getIdentify() { 
 return identify; 
 } 
 public void setIdentify(String identify) { 
 this.identify = identify; 
 } 
 
 
}

4.登錄成功后的主界面

import edu.gzu.stuManager.Domain.StudentInfo; 
 
public class StudentMainView{ 
 private JFrame frame; 
 private JTextField textField; 
 private JTextField textField_1; 
 private JTextField textField_2; 
 private JTextField textField_3; 
 
 private StudentInfo info; 
 
 /**

 */ 
 public StudentMainView(StudentInfo info) { 
 this.info=info; 
 } 
 
 public JFrame getFrame(){ 
 initialize(); 
 return frame; 
 }

 textField_3.setColumns(10); 
 
 JPanel panel_1 = new JPanel(); 
 panel_1.setBounds(317, 52, 110, 180); 
 frame.getContentPane().add(panel_1); 
 panel_1.setLayout(null); 
 
 JLabel lblNewLabel_6 = new JLabel("\u64CD\u4F5C\u83DC\u5355"); 
 lblNewLabel_6.setBounds(15, 10, 54, 15); 
 panel_1.add(lblNewLabel_6); 
 
 Button button = new Button("\u7B2C\u4E00\u95E8\u8BFE\u7A0B");

 choice.setBounds(10, 149, 76, 21); 
 choice.add("選擇課程"); 
 choice.add("高等數(shù)學"); 
 choice.add("大學英語"); 
 choice.add("大學體育"); 
 choice.add("概率與統(tǒng)計"); 
 choice.add("計算機圖形學"); 
 choice.addItemListener(new ItemListener() { 
 
 @Override 
 public void itemStateChanged(ItemEvent e) { 
 Object[] objs=e.getItemSelectable().getSelectedObjects(); 
 for(Object ob:objs){ 
//  JOptionPane.showMessageDialog(frame, ob.toString()); 
  if("高等數(shù)學".equals(ob.toString())){ 
  textField_2.setText("高等數(shù)學"); 
  textField_3.setText("98"); 
  }else if("大學英語".equals(ob.toString())){ 
  textField_2.setText("大學英語"); 
  textField_3.setText("87"); 
  }else if("大學體育".equals(ob.toString())){

  textField_2.setText("概率與統(tǒng)計"); 
  textField_3.setText("73"); 
  }else if("計算機圖形學".equals(ob.toString())){ 
  textField_2.setText("計算機圖形學"); 
  textField_3.setText("97"); 
  } 
 } 
  
  
 } 
 }); 
 
 panel_1.add(choice); 
 } 
 
}

這樣就能輕松實現(xiàn)登錄驗證了，本打算從數(shù)據(jù)庫讀取數(shù)據(jù)的，由于時間關系，這里就簡單的直接驗證了，后續(xù)有時間的話再做其他的部分。
