Answer 1

    import java.util.Scanner;

    public class LeapYear {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the year then press Enter : ");
        int year = input.nextInt();

        if ((year < 1580) && (year % 4 == 0)) {
            System.out.println("Leap year: " + year);
        } else {
            if ((year % 4 == 0) && (year % 100 != 0) || (year % 400 == 0)) {
                System.out.println("Leap year: " + year);
            } else {
                System.out.println(year + " not a leap year!");
            }

        }
    }
}
