title: Store two values in HashMap value
body: <p>I want to store two values in hashMap's value field.</p>
  
  <p>For example:</p>
  
  <pre><code>Key = 100, Value = 10, 20
  </code></pre>
  
  <p>I want to store in a way so that I could modify hashMap <code>Value</code> value using key ? </p>
  
  <p>Lets say If I want to modify 10 to 30 then entry in map would be </p>
  
  <pre><code>Key = 100, Value = 30, 20
  </code></pre>
  
  <p>Any way so that I could control both <code>Value</code> values independently using key of hashmap ..?</p>
