Array[] Size Question
I have written a simple program that reads in 30 first names from a txt file into an array and 20 surnames from another txt file into another array. All I want to know is, is it possible to create an array with no size specified, have the size defined by the number of names I read in from the txt file.
Does that make sense?

Re: Array[] Size Question
An array's size is fixed with it is created. You app sounds like it should use an ArrayList
If you don't understand my answer, don't ignore it, ask a question.
Re: Array[] Size Question
If the data in the file varies, then consider setting the size of the array at runtime.

Thanks. I was thinking something like that.Originally Posted by Starstreak
What I have done now, is just created a getFileSize method that takes the file name as a parameter and returns an int (the size of the file).
Re: Array[] Size Question
That would give the number of bytes. Is that what you need?
I was thinking of using a while loop with hasNextLine() to count the lines.
Re: Array[] Size Question
I should have mentioned that in my getFileSize method I do have a while loop and a counter. Its the counter that is returned.
I have it working this way. Thanks for the replies.
