java - Whitespace matching regex in Java

Question

I am currently trying to make use of the java string function someString.replaceAll() to find commonly used words (and, the, by, of, etc) and replace them with " ". Based on the answers to the question at Whitespace Matching Regex - Java, I produced this function call:

data.replaceAll("(?i)\\sthe\\s", " ")

However, it isnt working and I'm really not sure why. Nothing about it looks wrong based on what I've found. Please help me!

Answer 1

字符串是不可变的！

data = data.replaceAll("(?i)\\sthe\\s", " ");
