<p>I have an array of String but I do not know how many elements in it. If the user put 3 elements in the array then the total of index = 3. How can I scan all the elements array if it is not equal to '' (<em>meaning NULL</em>) and get the total of index in the array? <br/>
Thank you in advance</p></div>
