title: Extracting multiple string to constant in Intellij IDEA
body: <p>In my code, there are a lot of strings appeared in the following structure:</p>
  
  <pre><code>map.put("string_1", value_1);
  map.put("string_2", value_2);
  // etc.
  </code></pre>
  
  <p>I would like to extract the string key to a constant. However, doing this one by one will take forever...So, is there a better way to achieve this?</p>
