Regex won't stop matching

I have the following set of strings - "Hello.There" and "HelloWorld.There"

If I do a 'Hello.*', RegEx returns both strings. How do I change my expression to return only "Hello.There"?

You can use word boundaries in your regex:

^Hello\b.*$

With word boundaries it won't match HelloWorld

Your regex should be Hello\. if you want to return the string when its only contains Hello.

In regex a dot(.) means any character. You can escape this by using a escape character like this \.

\bHello\.There\b

the . character is a special character in Regex. Escape it.
