# Code from Enthuware mocks exams #


outputs : a aa aaa
because there is no "x" in the string so no match found and a single token is returned (original string)

but when i make changes to above code by putting a space before delimiter :

as i can see, here also the delimiter we specify should not match in the string as there is not any " x" in the string, then why is output :
a
aa
aaa


In the same way, why

returns zero token
but returns one token ( a empty string ) ?

Puspender,
The StringTokenizer API is tricky. Each character in the delimiters are characters not a sequence. That means " x" splits on spaces OR x. That's why you get the three tokens - there are there are two spaces so three portions.

For the second example " a" splits on spaces or a. Which is all the characters.
