title: get all the values from a hash table
body: <p>I'm working on an Android project in which I have to get all the values from a <strong>hash table</strong> regardless the key. My map is</p>
  
  <pre><code>HashMap&lt;String, ArrayList&lt;MyProduct&gt;&gt; orderAdap = InvocieProductFragment.mapOrderd;
  </code></pre>
  
  <p>And from this map I'm loading relevent Product ArrayList according to <strong>product name</strong>.</p>
  
  <pre><code>ArrayList&lt;MyProduct&gt; lstStyle = orderAdap.get(lstBrandCode.get(position));
  </code></pre>
  
  <p>But my problem is can I load all the Product lists into a single ArrayList without concerning <strong>key values</strong> in this hash map.</p>
  
  <p>For instance imagine my hash map is something like this.</p>
  
  <pre><code>[ss,[p1,p2,p3]],[we,[p3,p4]],[rf,[p1,p4,p5,p7,p9]]
  </code></pre>
  
  <p>and I need the output as</p>
  
  <pre><code>[p1,p2,p3,p3,p4,p1,p4,p5,p7,p9]
  </code></pre>
  
  <p>Can this be done. Need help. Thanks.....</p>
