title: \x Escape in Java?
body: <p>I was wondering if there is a similar hex (\x) escape in Java like there is in C++.
  For example:</p>
  
  <pre class="lang-cpp prettyprint-override"><code>char helloworld[] = "\x48\x45\x4C\x4C\x4F\x20\x57\x47\x52\x4C\x44";
  printf("%s", helloworld);
  </code></pre>
  
  <p>There is no hex (\x) escape in Java from what it appears so far. Is there an alternative that is just as easy to use without having to concat a bunch of hex numbers together?</p>
