Create a Java program which asks the user for two numbers and answers, using the conditional operator (?), the following:

- If the first number is positive
- If the second number is positive
- If they are both positive
- Which one is smaller


Source Code:


import java.util.*;

public class Main
{
	public static void main(String[] args)
	{
		int a, b;
		String answer;

		System.out.print("Enter the first number: ");
		a = Integer.parseInt(new Scanner(System.in).nextLine());

		System.out.print("Enter the second number: ");
		b = Integer.parseInt(new Scanner(System.in).nextLine());

		if (a > 0)
		{
			System.out.println("a is positive");
		}
		else
		{
			System.out.println("a is not positive");
		}

		if (a > 0)
		{
			answer = "a is positive";
		}
		else
		{
			answer = "a is not positive";
		}

		System.out.println(answer);

		answer = a > 0 ? "a is positive" : "a is not positive";
		System.out.println(answer);

		System.out.println(b > 0 ? "b is positive" : "b is not positive");

		answer = (a > 0) && (b > 0) ? "both are positive" : "not both are positive";
		System.out.println(answer);

		int smallest = a < b ? a : b;
		System.out.printf("Smallest: %1$s" + "\r\n", smallest);
	}
