Answer 1

ok this is what i got so far
import java.io.*;
public class ReverseDigit
static BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
public static void main (String[] args) throws IOException
IntClass integers = new IntClass();
reverseDigit(integers);
public static void reverseDigit(IntClass digit) throws IOException
     int d;
     System.out.print("Enter integer numbers:");
     System.out.flush();
     d = Integer.parseInteger(keyboard.readLine());
     digit.setNum(d);
     System.out.println("\nThe number entered is " + d);
     int digRev = 0;
     while (d != 0)
          digRev = digRev * 10 + d % 10;
     d = d / 10;
     System.out.println("\nThe number reversed is " + digRev);
