It's been a while since I Java-ed, but doesn't it "append" them, as in 
convert the integer to a string and then join the two strings, rather 
than "add" them (which I take to mean "calculate the sum of")?

(That's probably what you meant, but I'm just checking.  I'd be 
surprised to find that Java actually performed the string-to-value 
conversion implicitly.)
