Scanner in = new Scanner(System.in);

System.out.print("Enter the number to check: ");

int num = in.nextInt();

boolean isPronic = false;

for (int i = 1; i <= num - 1; i++) {

if (i * (i + 1) == num) {

isPronic = true;

break;

}

}

if (isPronic)

System.out.println(num + " is a pronic number");
