How to set max limit for each word in the sentence using Regex in JAVA

Question

I want to throw an error when the word exceeds max length, but not the whole sentence length.

Example

if I am setting max length as 10, the sentence is "Hello stackOverflow" this should throw error since stackoverflow length more than 10 if I give as "Hello stack Overflow" Should be passed since none of the word is not exceeding max length 10. This should be achieved using Regex in Java

Answer 1

The following code snippet does what you request using the sample string in your question.

java.util.regex.Pattern pattern = java.util.regex.Pattern.compile("\\w{11,}");
java.util.regex.Matcher matcher = pattern.matcher("Hello stackOverflow");
if (matcher.find()) {
    throw new Exception("Word too long.");
}

The regular expression searches for a series of at least eleven word characters and throws an exception if a match is found.
