Revise the program in number 9 above to throw a NegativeNumberException if the user enters a negative number.

What will be an ideal response?

```
import java.util.*;
public class GetNumbers2
{
public static void main(String args[]) throws InputMismatchException,
NegativeNumberException
{
Scanner stdin = new Scanner(System.in);
System.out.print("Enter the first non-negative number: ");
int firstNumber = stdin.nextInt();
if(firstNumber < 0)
throw new NegativeNumberException();

System.out.print("Enter the second non-negative number: ");
int secondNumber = stdin.nextInt();
if(secondNumber < 0)
throw new NegativeNumberException();
System.out.println("Your numbers are " + firstNumber + "and " +
secondNumber);
}
}

```
