Array fundamental
<p>I have one array size of 11 with String, i add some item in it.</p>

<h2>Decalration::</h2>

<pre><code> String arr_sound[] = new String[11];
</code></pre>

<h2>Initialization::</h2> 

<pre><code>arr_sound[0] = "bike_route.mp3";
    arr_sound[1] = "closed.mp3";
    arr_sound[2] = "exit.mp3";
    arr_sound[3] = "no_parking.mp3";  
                 ....
                 ....
    arr_sound[11] = "touch_and_show.mp3";
</code></pre>
