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.
