姑姑：给小学生出点口算题

姑姑带着妹妹来我家玩，让我给孩子出点口算题，我当仁不让，直接出了1000题给妹妹做。
效果如下，内容存在了txt中。


下面是代码，只需要改几个变量就能改出题的量和难度。

/** * @version 1.0 * @author: Pig One * @date: 2022/8/1 10:46 * @decription: 出几条10以内的加减法给孩子做做 */
public class Arg_10 {
    
    //做10以内的加减法，两个加起来不超过十
    final static int MAX_SUM = 10;
    //一天昨天20道题题
    final static int DAY_TASKS = 20;
    //一共多少天的量
    final static int DAYS = 50;

    public static void main(String[] args) {
    
        try {
    
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("/Users/zhuyi/IdeaProjects/Spirng5Learn/demo01/src/com/zy/LCSummer/task.txt")));
            BufferedWriter writerRes = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("/Users/zhuyi/IdeaProjects/Spirng5Learn/demo01/src/com/zy/LCSummer/res.txt")));
            for (int i = 0; i < DAY_TASKS * DAYS; i++) {
    
                int a = new Random().nextInt(MAX_SUM);
                int b = new Random().nextInt(MAX_SUM);
                //两数之和大于10且不为0
                while ((a + b) > MAX_SUM || a == 0 || b == 0) {
    
                    a = new Random().nextInt(MAX_SUM);
                    b = new Random().nextInt(MAX_SUM);
                }
                if (i == 0) {
    
                    writer.write("口算 1000题");
                    writerRes.write("口算 1000题 答案");
                }
                if (i % DAY_TASKS == 0) {
    
                    writer.write("\n\n");
                    writerRes.write("\n\n");
                    writer.write("day " + (i / DAY_TASKS + 1));
                    writerRes.write("day " + (i / DAY_TASKS + 1) + " answer");
                    writer.newLine();
                    writerRes.newLine();
                }
                String task = (i % DAY_TASKS + 1) + ": " + a + " + " + b + " = ? ";
                String res = (i % DAY_TASKS + 1) + ": " + (a + b);
                writer.write(task);
                writer.newLine();
                writerRes.write(res);
                writerRes.newLine();
            }
// System.out.println(a+ "+" +b +"=?");
            writer.flush();
            writer.close();
            writerRes.flush();
            writerRes.close();
        } catch (IOException e) {
    
            e.printStackTrace();
        }
    }
}

快去折磨孩子吧！
对了，如果有小数，需要加一点判断把a、b变成浮点数。
妹妹：听我说谢谢你。
