title: Java equivalent of unsigned long long?
body: <p>In C++, I enjoyed having access to a 64 bit unsigned integer, via <code>unsigned long long int</code>, or via <code>uint64_t</code>. Now, in Java longs are 64 bits, I know. However, they are signed.</p>
  
  <p>Is there an unsigned long (long) available as a Java primitive? How do I use it?</p>
