Given the following code, and assuming readData( has been called from main(), what is the output if "EX" is read into codeStr? public void main(String [] args) { Scanner kbd = new Scanner(System.in); readData( kbd); } catch (Exception e) { System.out.println("An Exception occurred"); } finally { kbd.close(); System.out.println("Done."); } } public static void readData( Scanner in ) { String numStr. codeStr; try { codeStr = in.next(); numStr = Character.toString( codeStr.charAt( 2)); int num = Integer.parseInt( numStr); } catch (NumberFormatException nfe) { System.out.println( numStr + " is not a number."); } } a. is not a number. Done. O b. An Exception occurred Done. O c. An Exception occurred O d. Done
