这主要是根据请假需求做的一个界面，目前只做了学生部分的界面，而且没有录入功能，只有简单的事件处理功能；

主要用到了用到了JTextfield,JpasswordField,JFrame,JButton,JLabel

JTextfield,JTextAraea这几个，

更新了io流版本的请假系统，基本的功能已实现，可到此链接查看：https://blog.csdn.net/qq_44716544/article/details/103658832

 

下边这个是请假系统代码

然后后边这个是登陆界面代码；

package sx;

import javax.swing.JPasswordField;
import javax.swing.JTextField;
import java.awt.*;
//import java.io.File;
//import java.io.IOException;

import javax.swing.*;

public class Login extends JFrame implements ActionListener {

	    JPanel jp=new JPanel();
	      
		  JTextField fieldAccount = new JTextField(1000);
		 
		  JPasswordField fieldPassword = new JPasswordField(1000);
		 JButton jb1 = new JButton("登 录");
		 
		  JButton jb2=new JButton("退出");
		  
		  JLabel label = new JLabel("  帐  号   ");
		  JLabel label1 = new JLabel(" 密 码   ");
		  JLabel label2=new JLabel("请假系统登录界面");
		  ImageIcon img1=new ImageIcon("src/12.jpg");
		  JLabel label0 = new JLabel(img1);
//		  public void paint(Graphics g){
//				 super.paint(g);
//				 ImageIcon imge=new ImageIcon("src/12.jpg");

其实代码没这么多的，大部分都注释掉了的，主要是删删改改然后多余的代码就留在那里了
