关于#Java#的问题，如何解决？
设计与实现一个小学生四则运算考试系统要求:
(1）要用Java Swing组件设计GUI界面
(2)能够进行加、减、乘、除四种运算，能够自动出题，自动计时，自动
判断对错并评分，可以注册用户保存用户信息到文件中，可以读取文件并完成登录验证。
只用写基础运算
这个问题不是很难，但是很费时间，自己搞一搞应该还是可以搞出来的。swing开发，可以关注我～有问题好交流
回答：折磨，绝对的折磨，还不如用Winform，哭死了，这调格式得调哭死
package calculate;
import javax.swing.*;
import javax.swing.border.LineBorder;
import java.awt.*;
