title: How to get particular key and value from Map
body: <p>I have searched but could not find a way to print only single key, value pair for particular entry. </p>
  
  <p><code>map.containsValue(value) or map.containsKey(key)</code></p>
  
  <p>will only tell if particular value or key is available or not.
  I want to print that particular key, value pair <code>if (value is available)</code>
  In other link, They want to get the random value, if you do not know the key. Here I know key and value and want to print it for particular key and value.</p>
