title: Adding alphabets to a Java HashSet
body: <p>I want to add all lowercase alphabets to a Java HashSet. For this I use the following code snippet:</p>
  
  <pre><code>for(char c = 'a'; c &lt;= 'z'; c++)  
      set.add(c);
  </code></pre>
  
  <p>Is there a better way to do this, like one in which I don't have to iterate over all the alphabets?</p>
