Use proper Java syntax, like

str.split(",")[0].equals("23")

Thanks for quick response. str.split(",")[0] == 1 works fine. What if 'str' is not String, it is of type Object? How can we cast that object to String and do that operation? eg. ((String)str).split(",")[0] == 1. This throws error in my system. – Chanduru Pushpalingam Jun 21 '16 at 05:15
