Java Regex to Validate Full Name allow only Spaces and Letters

Question

I want regex to validate for only letters and spaces. Basically this is to validate full name. Ex: Mr Steve Collins or Steve Collins I tried this regex.

Answer 1

My personal choice is: ^\p{L}+[\p{L}\p{Pd}\p{Zs}']*\p{L}+$|^\p{L}+$, Where:

^\p{L}+ - It should start with 1 or more letters.

[\p{Pd}\p{Zs}'\p{L}]* - It can have letters, space character (including invisible), dash or hyphen characters and ' in any order 0 or more times.

\p{L}+$ - It should finish with 1 or more letters.

|^\p{L}+$ - Or it just should contain 1 or more letters (It is done to support single letter names).

Support for dots (full stops) was dropped, as in British English it can be dropped in Mr or Mrs, for example.
