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

This previous SO question should shed some light on the subject, in your case you basically end up adding their ASCII values (71 for G) + (111 for o) = 182, you can check the values here).

You will have to use the String.valueOf(char c) to convert that character back to a string.
