How to iterate through List in a hashmap value
<p>I have a <code>HashMap</code> with <code>String</code> as key and <code>List</code> as value.</p>

<p>Name of the <code>HashMap</code> is <code>pageMap</code>.</p>

<p>Say this <code>pageMap</code> has the following key and value:</p>

<pre><code>key = order
value = [page1, page2, page3]
</code></pre>

<p>now I want to display in the following pattern:</p>

<pre><code>order
   page1
   page2
   page3

key2
   value1
   value2
   value3
   value4
</code></pre>

<p>Please tell me how do I do that?</p>
