To grasp how this works you first need to understand the access pattern of a Matcher to its CharSequence.

为了掌握这种方法，首先需要理解Matcher到其CharSequence的访问模式。

This expression is then retained by the Pattern class before it is passed on to the Matcher class to check for matches in the context of a character sequence.

Pattern先保存要使用的表达式，然后将其传递给Matcher 类以便在字符序列的上下文中检查其匹配情况。

youdao

In Listing 1, once a regular expression is compiled into a Pattern, it creates a matcher with the matcher method.

在清单1中，一旦将正则表达式编译成Pattern，它就创建了带matcher方法的matcher。

These two classes — pattern and Matcher — are the whole pattern-matching library.

这两个类(Pattern与Matcher)就是整个模式匹配库。

But if you want to fetch specific input, you'll need the matcher method of Pattern When given some input, this method will return the appropriate matcher class.

但如果您想获取特定的输入，您将需要Pattern的matcher方法。
