Question

很难解释这个问题，但是我会尽力而为。基本上我希望程序读取文本文件的第1-6行，然后读取第7-12行，然后是13-18。但现在不是。

我的输出是：

忽略左上方的数字，这样我就可以在按钮上测试我的锁了。

我不知道该怎么做。任何帮助将不胜感激。

我是个白痴

for(int i = 0; i < question; i++){
        br.readLine();
        br.readLine();
        br.readLine();
        br.readLine();
        br.readLine();
        br.readLine();
    }

    for(int i = 0; i < 6; i++){
        array[i] = br.readLine();
    }

完成
