Final Answer :
import java.util.*;
public class GetNumbers2
{
public static void mainString args[])
{
Scanner stdin = new ScannerSystem.in);
try
{
System.out.print"Enter the first non-negative number: ");
int firstNumber = stdin.nextInt);
System.out.print"Enter the second non-negative number: ");
int secondNumber = stdin.nextInt);
System.out.println"Your numbers are " + firstNumber + "and " +
secondNumber);
}
catchInputMismatchException e)
{
System.out.println"Please enter a positive integer.");
}
}
