RegEx for not expecting special character excluding single quote

Question

I googled this but it's not working fine.

Please provide me a better solution.

I use this ^([a-zA-Z]+)$ but it is not excepting single quote.

I only allow the string for example aaa'bbb.

This is a very basic question, to get started with regexes look at **[this answer](http://stackoverflow.com/questions/22937618/reference-what-does-this-regex-mean/22944075#22944075)** and particularly the Character Classes part. — asontu, Nov 06 '14 at 12:42

You can try below regex. It will take any Single Word Character (Not Whitespace) thrice and then quote and again any Single Word Character (Not Whitespace)

aaa'bbb

You need to use this "^([a-zA-Z\']+)$" as regular expression string to allow single quote in your input string.

Here is an example.

public static void main(String[] args)
{
    String s= "Abc'abc";
    System.out.println(s.matches("^([a-zA-Z]+)$"));//Output will be false will not allow single quote in input
    System.out.println(s.matches("^([a-zA-Z\\']+)$"));//output will be true will ALLOW single quote in input
}

Best luck Anant
