                                    Arrays in Java have a defined size, you cannot change it later by adding or removing elements (you can read some basics here). Instead, use a List : ArrayList&lt;String&gt; mylist = new ArrayList&lt;String&gt;(); mylist. add(mystring); //this adds an element to the list.

Thank you! 6
