Please invest some time in learning. Putting a requirement straight away as a question will lead to nothing. As you have seen, your question is already downvoted. BTW, I have not downvoted. Better to try with something and edit your question in order to show your effort. — vinS, Dec 13 '17 at 12:14

((?!Mr).)* matches string that doesn't contain "Mr.". If you check it before and after of the word "Approved", you're done.

^((?!Mr.).)*Approved((?!Mr.).)*$

Example:

Abc your request is Approved. -> Match
Mr. Abc your request is Approved. -> No match
Abc your request is Approved. Mr. -> No match
Abc your Mr. request is Approved. -> No match

This should do it

^(?!Mr).*(Approved).*

It will select those lines which doesn't start with Mr, but have the word Approved inside (it can or not be at the end )

You may check my answer. If anything is missing, notify me. – Dorukhan Arslan Dec 13 '17 at 12:27
I think that won't check neither if `Mr` appears after `Approved` [Take a look](https://regex101.com/r/hr0r8k/4) – alseether Dec 13 '17 at 12:30
Huh? It checks as it seen. OP says if "Mr." appears in sentence, don't match it. In this link, the expected result is shown. – Dorukhan Arslan Dec 13 '17 at 12:35
Yeah yeah, completely true, i said nothing XD – alseether Dec 13 '17 at 12:44

Maybe this regex can help you ^(?i)((?=\bApproved\b).)*((?!\bMr\b).)*$

String approved = "Abc your request is Approved.";
String notApproved = "Mr. Abc your request is Approved.";
String regex = "(?i)((?=\\bApproved\\b).)*((?!\\bMr\\b).)*";

If you use :

System.out.println(approved.matches(regex));
System.out.println(notApproved.matches(regex));

Outputs

true
false

Regex if contain word 'ABC' select and if contain 'EFG' dont select even if it contains 'ABC'
