Regarding calculating the size of list which is internally is a value of Map
<p>I have query I have a Map which consist of key and valuses will be of type list </p>

<pre><code>Map&lt;String, List&lt;String&gt;&gt; ppvValidatedinfo = new Map&lt;String, List&lt;String&gt;&gt;
</code></pre>

<p>Now I am adding some data into the map initially</p>

<pre><code> 1234 , 456987
</code></pre>

<p>but next time when data added to map it becomes like this</p>

<pre><code>1234 , [456987,125789]
</code></pre>

<p>As shown above that 1234 is key and 456987,125789 are the values internally maintened 
  in list and are the values of the map</p>

<p>Now my query is that I have to go in flow where list size increases more than 1 please advise   how can i track the size of the list , I want to track the size of the list which is a value of map</p>
