Hi vbrun,
I think u have made mistake while using split method. There should be " "
i.e space between the quotes ( " " ) not ( "") so as to separate out
firstName with the lastName.
Also in the end you have written System.out.println(firstName1); it will
just print the className@hashcode .To resolve this
write System.out.println(firstName1[0]); .
This is because firstName1 is String array object whose toString() method is
not overridden while firstName1[0] is just a simple String object
whose toString()
method is overridden to print the actual string value .
