how to add a new element to an existing array?

If you feel the need to resize an array, better have a look at the ArrayList
Simple arrays cannot be resized, i.e. if you want to add more elements you
have to allocate another array (big enough) and copy everything from the old
to the new array.

True, but you can get an ordinary array from an ArrayList. Read the API docs.
Pay special attention to the overloaded toArray() methods.
