title: How to Convert byte array to hexString in java?
body: <p>I have byte array that consist of hex values like <code>CA ,FA,21,33</code></p>
  
  <p>But I want to list them in <code>JList</code> as a single element <code>CAFA2133</code>.
  In order to list them in JList I think I need to convert it to <code>string</code>.
  So any recommendation?</p>
