title: Java: Converting byte string to byte array
body: <p>I want to convert my <code>byte[]</code> to a <code>String</code>, and then convert that <code>String</code> to a <code>byte[]</code>.</p>
  <p>So,</p>
  <pre><code>byte[] b = myFunction();
  String bstring = b.toString();
  /* Here the methode to convert the bstring to byte[], and call it ser */
  String deser = new String(ser);
  </code></pre>
  <p><em>bstring gives me <code>[B@74e752bb</code>.</em></p>
  <p>And then convert the <code>String</code> to <code>byte[]</code>. I'm not using it in this order, but this is an example.</p>
  <p>How do I need to do this in Java?</p>
