title: Converting letters to alphabet position with two JLists
body: <p>I'm trying to replace all words (alphabet letters) from JList1 to the number corresponding its place in the alphabet to JList2 with the press of the Run button. (ex. A to 01) And if it's not an English alphabet letter then leaving it as it is. Capitalization doesn't matter (a and A is still 01) and spaces should be kept.</p>

  <p>"Apple!" should be converted to "0116161205!"<br>
  "stack Overflow" to "1920010311 1522051806121523"<br>
  "über" to "ü020518"</p>
  
  <p>I have tried a few methods I found on here, but had zero clue how to add the extra 0 in front of the first 9 letters or keep the spaces. Any help is much appreciated.</p>
