Why does concatenated characters print a number?

Question

I have the following class:

   public class Go {
     public static void main(String args[]) {
      System.out.println(\"G\" + \"o\");
      System.out.prin         


        

Answer 1

System.out.println("G" + "o");
  System.out.println('G' + 'o');

First one + is acted as a concat operater and concat the two strings. But in 2nd case it acts as an addition operator and adds the ASCII (or you cane say UNICODE) values of those two characters.
