title: Convert a string from a custom base to another
body: <p>How do I convert a string (the string has numbers and alphabets) from a base (ranges from 1 to 64) to another base (ranges from 1 to 64).</p>
  
  <p>Now, I googled and found out a solution which does it.</p>
  
  <pre><code>String converted = Integer.toString(Integer.parseInt(input, radix1),radix2);
  </code></pre>
  
  <p>In the above line of code, the input is converted from radix1 to radix2 however, if the input is a string is for example:- "ZZZZ" and radix1 is 30 and I try to convert it to base 10, then I get an Exception.</p>
  
  <p>The characters allowed are "23456789ABCDEFGHJKMNOPQRSTUVWXYZ". Here 0, 1, I, and L are ommitted.</p>
