How to iterate over HashMap<String, ArrayList<Record>> in Java? : <p>I want to access the Records I have created in the HashMap.<br>
    Due to some requirements, I am unable to create a new data structure for holding my data.</p>

<pre><code>private HashMap&lt;String, ArrayList&lt;Record&gt;&gt; customerInfoTable = new 
HashMap&lt;String, ArrayList&lt;Record&gt;&gt;();
</code></pre>
