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

The plus in Java adds two numbers, unless one of the summands is a String, in which case it does string concatenation.

In your second case, you don't have Strings (you have char, and their Unicode code points will be added).
