Detect emails in text and pass it tag

Question

greetings of all I have text that can contain emails and I want to detect any occurrence of email and surround it with a tag < a > for example:

[e-mail]
<a href="mailto:[e-mail]"> [e-mail] </a>

Answer 1

Using the regular expression from regular-expression.info , you can do:

text = text.replaceAll("(?i)\\b([A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4})\\b",
                       "<a href=\"mailto:$1\"> $1 </a>");
