我目前有二维列表，其中将根据日期选择特定数据。我有一个方法，它查看日期，如果为真，它将把行追加到另一个列表中。目前，由于主列表包含大约 1000 个对象，因此我的代码运行缓慢，而且我似乎无法找到优化结果的方法。

最佳答案
这段代码真的很糟糕。为什么要向列表中添加四个“属性值”，而不是像 OOP 那样创建一个具有四个属性的类？ 这也可能会阻止您每次调用的时间密集型字符串到日期的转换。
为什么不遵循命名约定，例如大写类名？
´if (weekMatches(x) != null) gamesTwo.add(Arrays.asList(weekMatches(x).get(0), weekMatches(x).get(1), weekMatches(x).get(2) )));´ 是你的基本问题。你记忆、记忆、记忆所有的列表过滤过程。将其保存在变量中!
使用 for-each 循环使代码更具可读性。
每周Matches() 都会调用您将 team_fix_date 延长所有比赛日期......巨大的列表。 这应该在 CTOR 中完成一次。
该代码还有很多错误，我就在这里停下来。 不得不说的是，你真的应该捕获你无法完成的事情。
我将该代码重构为以下内容。尝试一下:
