Question

I have a textbox where I am taking input as full name.

When user enter input as My Name, I don’t get any error. However when user enter input as My Name Is, I get error.

Regex I have is

([a-zA-Z]+|[a-zA-Z]+\\s[a-zA-Z]+)

What actually want is, text should have

only (a-z OR A-Z) AND white space...

Demo Inputs are

1. My Name is XYZ PQR STU
2. My Name is XYZ
3. XYZ PQR STU

How this can be done using regex?

Update 1

I am using

    Pattern p = Pattern.compile("[a-zA-Z\\s]");
    Matcher m = p.matcher("DummyName");
    boolean matchFound = m.matches();

still I am getting matchFound as FALSE

\s is for whitespace. If you want to allow whitespace in a character class as well as upper and lowercase letters, you would use [a-zA-Z\s].
