Yes, I've just explained it in the original thread.

The splitting consists of splitting each string into two parts which
are collected ain an array. Thus nameArrayForPerson1[0] is the first
element of an array of String, it has a length as any other array of
string and this length is an integer, hence you don't need any casting
to affect this length to an integer.
See the Java doc for String, method split.
