    <b>Accessing properties inside Arrays
</p>
<p>
    To access properties inside arrays, use the brackets "[]" operators with the desired index(starting from 0). The action
    class has an array of String in the field <i>bands.
</p>
<p>
    To access the second element in the <i>bands array type:
</p>
<p>
    <i id="example0">
        bands[1]
    </i>
</p>
<p>
    on the OGNL console and hit enter. <a href="#" onclick="execOgnl('example0')">Do it for me
</p>
<p>
    <b>Accessing properties inside Lists
</p>
<p>Lists can be accessed on the same way. The action class has a List of String on the field movies.

<p> To access the first element in the <i>movies list type: </p> <p> <i id="example1"> movies[0] </i> </p> <p> on the OGNL console and hit enter. <a href="#" onclick="execOgnl('example1')">Do it for me </p> <br/> <p> <a href="#" onclick="window.open('http://www.ognl.org/2.6.9/Documentation/html/LanguageGuide/indexing.html#N10184')">[More details] </p>
