If the option pane returns string "s", you simply iterate through
the original array, comparing the value of each element in
that array to "s".  If you don't want to write the iterative
code to do this, hold the list in a vector and just as you are 
setting up the option pane, copy the contents of the vector into
an array:

  // assuming you have a vector vList containing your list

  String [] list = new String [vList.size()];
  vList.copyInto(list);
  String s = (String)JOptionPane.showInputDialog(
    ..., 
    list,
    list[3] );
  
  ...
  int index = vList.indexOf(s);
  if ( index > -1 ) ...
