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!

It isn't working - means? What output are you getting after that replace? — Rohit Jain

Meaning that it isn't replacing any of the words that I place in the regex with " ". It led me to assume that my regex wasnt matching the word, but I dont know why it isnt, since it looks right to me — taylorc93

commonly words without a pattern just use replace instead of replaceAll — nachokk

Can you post complete code? I tried the following and it seems to replace 'The' string with space. For input 'me The rt', the code below prints 'me rt'. String data = "me The rt"; String result = data.replaceAll("(?i)\\sthe\\s", " "); System.out.println(result); — user1573133

Strings are immutable!

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