开发100以内加减乘除的考试系统

Question

怎么设计出这种图文的考试系统，利用ntebeans 设计出这种图形化界面

Answer 1

学校的东西，步入社会用的太少了。我给你另一种写法，开发100以内加减乘除的考试系统
如有帮助，采纳

import java.util.Random;
import java.util.Scanner;
public class Main {
    public static void main(String[]args) {
        //启动界面
        System.out.println("--------------------------------");
        System.out.println("作者：XXX  学号：P20210304XXX");
//        System.out.println("-----------------------------");
        System.out.println("欢迎使用小学生数学练习系统v2.0");
        System.out.println("--------------------------------");
        System.out.println("按1进入练习系统，按0退出练习系统");
        System.out.println("--------------------------------");
        //输入0或1
        Scanner in = new Scanner(System.in);
        int num = in.nextInt();
        int dui = 0;

        //判断输入是否为0或1
        if(num==0||num==1||num==2||num==3||num==4) {
