Java 8中anyMatch和findAny之间的区别 [英] Difference between anyMatch and findAny in java 8

问题描述

我有一个Array，想对其元素进行一些匹配.

I have an Array and want to perform some matching on it's element.

我知道可以在java 8中以两种方式完成此操作:

I came to know that it could be done in two ways in java 8 :

String[] alphabet = new String[]{"A", "B", "C"};

anyMatch:

Arrays.stream(alphabet).anyMatch("A"::equalsIgnoreCase);

findAny:

Arrays.stream(alphabet).filter("a"::equalsIgnoreCase)
        .findAny().orElse("No match found"));

据我了解，两者都在做相同的工作.但是，我找不到哪个更喜欢?

As I can understand both are doing the same work. However, I could not found which one to prefer?

有人可以说清楚两者之间的区别是什么.

Could someone please make it clear what is the difference between both of them.

推荐答案

它们在内部执行相同的工作，但是它们的返回值不同. Stream#anyMatch() 返回boolean，而 Stream#findAny() 返回与谓词匹配的对象.

They do the same job internally, but their return value is different. Stream#anyMatch() returns a boolean while Stream#findAny() returns an object which matches the predicate.
