java - 如何在java中的字符之间使用.matches来匹配包含.*的字符串

Question

String str1 = "My hobby is playing \"Tennis\" I am good at it. I love it."
String str2 = "My hobby is playing \"Tennis\". I (Alex) am good at it. I(Alex) love it. "

我想检查 str1 是否与 str2 匹配，除了 Alex 部分。

注意 - Alex 是这里的一个变化部分。可能是汤姆、哈利等。

所以我尝试了:-

str2 = "My hobby is playing \"Tennis\". I (.*) am good at it. I(.*) love it. "
str1.matches(str2)

但它返回 false。

我在这里做错了什么？

它适用于:-

str2 = "My hobby is playing \"Tennis\". I (.*)

Answer 1

您的正则表达式将匹配“I”和“am”之间的两个空格，因此它不会匹配字符串

"My hobby is playing \"Tennis\" I am good at it. I love it."

因为那里只有一个空格。而且，你错过了“网球”之后的点。不过，请注意“.”。在正则表达式中具有特殊含义。所以你想转义正则表达式中的点

尝试:

"My hobby is playing \"Tennis\"\\. I (?:\\(.*\\) )?am good at it\\. I (?:\\(.*\\) )?love it\\."

以上内容将匹配两者:

My hobby is playing "Tennis". I am good at it. I love it.
My hobby is playing "Tennis". I (Alex) am good at it. I (Alex) love it.
