Answer 1

Here's the answer in a riddle - to fill in the blank line is to understand the algorithm used - have fun!
class BinaryConverter{
   public static void main(String []args) throws Error{
      try{
         new BinaryConverter(Integer.parseInt(args[0]));
      }catch(ArrayIndexOutOfBoundsException e){
         System.out.println("No argument entered");
      } catch(NumberFormatException e){
         System.out.println("Enter whole numbers only");
   private BinaryConverter(int i){
      System.out.println("The binary number is: ");          
      convert(i, 0, (long)Math.pow(2, 31));
   private void convert(int num, int i, long max){
      if(num / max==1) System.out.print("1");
      else System.out.print("0");
      num %= max;
      // there is a line deliberately removed here!
      if(i++ % 8 ==0) System.out.print(" ");
      if(max >0) convert(num, i, max);
}
