Regex Expression for Specific string in Java

Question

I am new to Regex expression so not able to validate the String which can have number 0-9 FGHC,and fghc *#.

I am trying with [0-9FGHCFGHC*#] its working with regex tool but in java its not working.I am using java 1.7

Egfor this pattern I required it like 2314F*Ghc 12fgH# etc.

public static void main(String[] args){
    String money = "23FGhc*#";
    Pattern p = Pattern.compile("[0-9FGHCfghc*#]",Pattern.CASE_INSENSITIVE);
    Matcher m = p.matcher(money);
    if (m.matches())
        System.out.println("valid:-"+ m);
    else
        System.out.println("unvalid:- "+m);
}

Thank in Advance for your help and it will be more help that you explain the soultion so I can have more knowledge in RegEx

Answer 1

(?i)[0-9fghc*#]+

You need to add a quantifier at the end as well. In this case + to match these characters one or more times.

Use can also add (?i) to make it case insensitive.
