Please correct me if not, but I think this question is more related to Java than Appian RPA but here is fuction

public static String isValidName(String name) 
	{ 
		if (name != null) {		 

			String[] ar = name.trim().split("-");

			if (ar.length>1) {
				return ar[1];
			}
		}
		return "error";
	}
