just wanted to check something,

would this work?

string forename = "john"
string surname = "smith"

username = forename.substrings(1, 3) + surname.substring(1, 3);

output would be johsmi?

its a question about string concatenation

Nope, output is "ohmi"

Strings start at 0 and the last index is exclusive (not inclusive)
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#substring(int, int)

ah cheers, so would it be (0, 2)?
