It would be best to use a regular expression.  You could also get the positions of the various delimiter characters and then get the text between the first and second, then the third and fourth if there are more, etc.

Hello,@likecoding

Please try this code,To How to return string between special characters

public static String innerSubString(String txt, char prefix, char suffix) {

    if(txt != null && txt.length() > 1) {

        int start = 0, end = 0;
        char token;
        for(int i = 0; i < txt.length(); i++) {
            token = txt.charAt(i);
            if(token == prefix)
                start = i;
            else if(token == suffix)
                end = i;
        }

        if(start + 1 < end)
            return txt.substring(start+1, end);

    }

    return null;
}

I hope this code will be useful for you.
