1. What is the output of the following program?

public class Exercise8

{

public static void main(String[] args)

{

guessOutput(7654321);

} // end main

public static void guessOutput(int n)

{

if (n > 0)

{

System.out.print(n % 10 + " ");

guessOutput(n / 10);

} // end if

} // end guessOutput

} // end Exercise8

2. Identify and fix the errors in the following program:

public class Exercise9

{

public static void main(String[] args)

{

guessOutput(7654321);

} // end main

public static void guessOutput(int n)

{

if (n != 0)

{

System.out.println(n);

guessOutput(n / 10);

} // end if

} // end guessOutput

} // end Exercise9
