Stuck on the java problem below, help completing the problem would be appreciated thank you!

PROBLEM: "Complete this program, prompting the user to to enter two positive numbers a and b so that a is less than b. "

CODE BELOW:

import java.util.Scanner;

public class TwoNumbers { public static void main(String[] args) { Scanner in = new Scanner(System.in); boolean i = true;

// Keep prompting the user until the input is correct System.out.println("Enter two positive integers, the first smaller than the second."); System.out.print("First: "); int a = in.nextInt(); System.out.print("Second: "); int b = in.nextInt();

// Only print this when the input is correct System.out.println("You entered " + a + " and " + b); } }
