java - 一个正则表达式问题

Question

在 Java 的正则表达式中，我想匹配任何包含单词“Mary”和单词“are”的句子，但在“Mary”和“are”之间不包含“Bob”。

Eg: Mary and Rob are married - MATCH
Eg: Mary and John and Michael became good friends and are living together <- MATCH
Eg: Mary, Rob and Bob are dead <- does not MATCH

有什么想法吗？

一个更短的版本:

(?m)^.*\bMary\b((?!\bBob\b).)*\bare\b.*$


public class Main {
    public static void main(String[] args) {
        String[] tests = {
                "Mary and Rob are married",
                "Mary and John and Michael became good friends and are living together",
                "Mary, Rob and Bob are dead"
        };
        String regex = "(?m)^.*\\bMary\\b((?!\\bBob\\b).)*\\bare\\b.*$";
        for(String t : tests) {
            System.out.println(t.matches(regex) + " -> " + t);
        }
    }
}
