title: Can we get value from hashmap without considering case of String key?
body: <p>I want to access java.util.HashMap without considering case of the key.</p>
  
  <p>By this, I mean, if I add following entry to my HashMap:</p>
  
  <pre><code>java.util.HashMap&lt;String, Object&gt; myMap = new java.util.HashMap&lt;String, Object&gt;();
  myMap.put("foo", new Foo());  // Note lower-case key used here
  </code></pre>
  
  <p>Then I should be able to get Foo object by following code:</p>
  
  <pre><code>Foo f = (Foo) myMap.get("FOO"); // Note UPPER-case key used here
  </code></pre>
  
  <p>Is this possible?</p>
  
  <p>Thanks.</p>
