title: Get object from HashMap which contains key substring
body: <p>I have a Map object which has <code>COM-20 HELLO</code> as key and <code>My name</code> as value.</p>
  
  <p>Is there any way to get this object by indicating that I want the key that contains <code>COM-20</code> without the <code>HELLO</code></p>
  
  <p>Thanks.</p>
