有些问题一直在寻找答案。我发现我的for循环迭代不正确它打印系列：0,1,2,10等我想知道是否有人可以指出我的缺陷，所以我可以解决这个问题。我很欣赏任何读这篇文章的人，以及代码长度的appolgozie。但只想包括一切，所以我不会错过任何东西。 FOR LOOP LINE 87 再次感谢，真诚的java noob

好的，通过看帖子，我只能指出一个问题。因为你在行

之前递增counterOfReadLines变量

playerNames [counterOfReadLines] = br.readLine（）;

所以会发生什么是playerNames正在初始化索引1的数组而不是0，当你试图调用下面的循环： - for（int i = 0; i＆lt; playerNames.length; i ++）{ Matcher m = p.matcher（playerNames [i]）;

csrftoken_cookie = [cookie for cookie in cookie_jar if cookie.name == 'csrf_token'][0]

它以0递增。因此要么从i = 1开始，要么在行后增加counterOfReadLines playerNames [counterOfReadLines] = br.readLine（）;

所以你的错误会消失......！如果没有让我知道...... :)！

for循环迭代无法找到让我跳跃值的东西
