How to use the least amount of memory to store a string in a hashset
<p>I have a large amount of strings that need to be stored in a very compact fashion. Currently I am storing the strings (32 characters a-f/0-9) in <code>HashSet&lt;byte[]&gt;</code>. I am simply calling <code>.getBytes()</code> to get this. </p>

<p>My question is, is there a better way to store this data in a hashset? </p>
