I expect the following line to result with the initials, “AM”, in the output, but instead outputs “142”? I would like to understand why this is:

    System.out.println(firstName.charAt(0) + lastName.charAt(0)); 
// What are the initials?

char + char = int
character (Unicode) value + character (Unicode) value = int

Which explains:
