Given string userString on one line and string personName on a second line, append a space to userString. Then, append personName to userString. Lastly, append an exclamation mark to userString. Ex: If the input is: You are Ron Hill then the output is: You are Ron Hill! public class ConcatenateString { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userString; String personName; userString = scnr.nextLine(); personName = scnr.nextLine(); /* Your code goes here */ System.out.println(userString); } }
