Thank you

Apology accepted It shows how careful you have to be when copying code.

Piet, what's a null string?
JT: please go through the Java™ Tutorials. The argument to String#split is a regular expression; it is called regex here. You will find | in the Tutorials' list of metacharacters. Plain simple “|” is interpreted as “nothing or nothing” which is why you are getting the String split into individual characters. To get a regular expression representing the upright bar or “pipe” character, you have to escape it, as Carey showed you.

1 2 3 4 5 6 7 8 9 0 are called “Arabic” numbers because they came to Europe from the Arabs. The concept of having those ten numbers actually originated in India.

I don't know whether you need to work out any Unicode numbers for a cert. exam, but for “Arabic” numbers and Latin letters, it should be very simple.

Thank you Yes, that does help.

I presume that is Boyarsky and Selikoff's book? Please give us the question number. I didn't find anything matching your point here, so you probably have a new erratum (well done).

Have you any idea whether that behaviour is fixed for all programs, and whether it is specified anywhere?

Congratulations, everybody

Yes, I had forgotten about that. It disappeared in Java6, just as using a static initialiser to allow you to execute code with no main method disappeared in Java7.

really just used for pointless interview questions about instances, equality, and GC.

Hahahahahahahahahahahahaha! Do they ever use it for cert. exam questions; I think not.
