How to find the exact word using a regex in Java?

When you use the matches() method, it is trying to match the entire input. In your example, the input “Print this” doesn’t match the pattern because the word “Print” isn’t matched.

So you need to add something to the regex to match the initial part of the string, e.g.


And if you want to allow extra text at the end of the line too:


Alternatively, use a Matcher object and use Matcher.find() to find matches within the input string:

    Pattern p = Pattern.compile("\\bthis\\b");
    Matcher m = p.matcher("Print this");



If you want to find multiple matches in a line, you can call find() and group() repeatedly to extract them all.
