title: Regex to validate Full name having atleast four characters
body: <p>I want to use regex to validate names. The names must contain, first name, middle name, last name (not necessarily all). But I also want to impose a condition that the name must be of at least four characters. I have found regex to validate full name here <a href="https://stackoverflow.com/questions/15805555/java-regex-to-validate-full-name-allow-only-spaces-and-letters">Java Regex to Validate Full Name ...</a> and found regex to check for checking of at least three chars (alphabets) in a string here <a href="https://stackoverflow.com/questions/15341016/regex-to-check-for-at-least-3-characters">Regex to check for at least 3 characters</a>. But I am not sure how to combine these two to obtain the desired result. Please help me to achieve the desired Regex, so that I can complete my project.</p>
