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

In the second case it adds the unicode codes of the two characters (G - 71 and o - 111) and prints the sum. This is because char is considered as a numeric type, so the + operator is the usual summation in this case.
