You can't. An array's size is fixed at creation time.

You can:

1) Replace an existing entry.

2) Create a new larger array, copy the existing elements into it, and then put the new entry into the last slot.

3) Use a Collection, such as an ArrayList or LinkedList.

Not knowing your requirements or what you're really trying to do, my initial inclination would be #3.

Im trying this from this page i found: http://www.developer.com/java/other/article.php/3343771

I tried this:

List ips = new ArrayList();

When I do that I get this error from the compiler:

FileInOut.java:8: cannot find symbol

symbol : class List

location: class FileInOut

List ips = new ArrayList();

FileInOut.java:8: cannot find symbol

symbol : class ArrayList

location: class FileInOut

List ips = new ArrayList();

2 errors

Any reason why this doesn't work?

Thanks,

Did you import java.util.List and java.util.ArrayList ?
