Collections.sort(list)和list.sort(Comparator)之间的区别
有什么理由让我更喜欢 Collections.sort(list)方法而不是简单地调用 list.sort()吗?在内部， Collections.sort 仍然只调用 List 类的 sort 方法.
Is there any reason why I should prefer Collections.sort(list) method over simply calling the list.sort()? Internally Collections.sort merely calls the sort method of the List class anyway.
令人惊讶的是，几乎每个人都告诉我使用 Collections.sort .为什么?
It's just surprising that almost everyone is telling me to use Collections.sort. Why?
方法 Collections.sort 自Java 1.2以来一直存在.
The method List.sort(comparator) that you are refering to was introduced in Java 8, whereas the utility method Collections.sort has been there since Java 1.2.
这样，您会在Internet上找到很多提及该实用程序方法的参考，但这仅仅是因为它在JDK中已经存在了很长时间.
As such, you will find a lot of reference on the Internet mentioning that utility method but that's just because it has been in the JDK for a lot longer.
请注意， Collections.sort 的实现更改是在8u20 中进行的.
