You could even try this expression   a-zA-Z  s    for checking a string with only letters and spaces  nothing else    For me it worked  Hope it works for you as well   Or go through this piece of code once       CharSequence inputStr   expression      Pattern pattern   Pattern compile new String     a-zA-Z  s            Matcher matcher   pattern matcher inputStr       if matcher matches                     if pattern matches           else                  if pattern does not matches

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

What about    Peter M  ller   Fran  ois Hollande   Patrick O Brian   Silvana Koch-Mehrin   Validating names is a difficult issue  because valid names are not only consisting of the letters A-Z   At least you should use the Unicode property for letters and add more special characters  A first approach could be e g    String regx        p L    -          p L  is a Unicode Character Property that matches any kind of letter from any language
