java - 如何使用 Java 将字符串中的多个单词替换为空格

Question

我尝试用以下代码替换给定字符串中的单词列表。

String Sample = " he saw a cat  running of that pat's mat ";
String regex = "'s | he | of | to | a | and | in | that";
Sample = Sample.replaceAll(regex, " ");

输出为

[ saw cat  running that pat mat ] 
// minus the []

它仍然有最后一个词“that”。无论如何，是否可以修改正则表达式以考虑最后一个单词。

Answer 1

尝试:

String Sample = " he saw a cat running of that pat's mat remove 's";
String resultString = Sample.replaceAll("\\b( ?'s|he|of|to|a|and|in|that)\\b", "");
System.out.print(resultString);

saw cat running pat mat remove
