title: how to convert a large integer to Ascii character string in java?
body: <p>I have seen many methods to convert string to ascii. 
  For example </p>
  
  <pre><code>"Nkn" = 78 + 107 + 110 = 78107110
  </code></pre>
  
  <p>But is there a way to easily convert back <code>78107110</code> to <code>"Nkn"</code> (Since ascii codes of each character can vary in length from 1 to 3)</p>
