Good evening, can I ask for some guidance with an issue I have with a small program?

I am having problems with a couple of classes using an ArrayList and an Iterator with a scanner reading in a file. When the file has been read in and another class attempts to return the elements in the Iterator, it only reports back every other entry from the file. So the file File1.txt contains 10 rows of Computer names, but when the program runs it only reports back 5 of the names.

The Class data is:




The next class is:




Thank you in advance.

Jin.

When you are running this to test it, do you have

uncommented?

That would explain things.

To clarify iter.next() is returning the next value and moving the iterator on.
So if you System.out(iter.next());
and then return(iter.next());
then you will take your 10 values and output 5 of them to the screen and return the other 5 from the function.

I got it....one different reason which exactly explains the flaw.
See the below code


getTheData method is called twice that explains why you get only half of the text from file.

try this : this will work.
