ArrayList中的对象是可比较的，对吗？

当你说想要查看是否他们匹配你的意思是如果它们在相同的位置包含相同的对象，对吧？


那么一个通过ArrayLists的简单循环应该这样做。

The objects in the ArrayList are Comparable, right?
When you say you want to see if they "match up" you mean if they contain equal objects at the same locations, right?

Then a simple loop going through the ArrayLists should do it.

它并不那么简单。我试图比较两个单独的文档，并找出更改的位置。我想通过某种类型的循环来找到一个与另一个相比较的变化。内容可以四处移动。

It is not that simple. I am trying to compare two separate documents, and find where the changes were made. I want to go through some type of loop to find the changes made on one comparred to the other. The contents may be moved all around.

这不是你在原帖中说的那样吗？那么这些文件是什么类型的？ .txt，.odt，e.t.c？

That is not what you said in your original post is it? So these documents are what type? .txt, .odt, e.t.c?
