Leap year
A leap year is a calendar year that includes an additional day to synchronize the calendar year with the astronomical or seasonal year. – Wikipedia
Logic
The Logic to check this is quite simple. We only need to check if the given year is multiple of 4 or 400, but it should not be multiple of 100.
Program
import java.util.Scanner;
public class LeapYear {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter a year : ");
int year = scanner.nextInt();
if (year % 4 == 0) {
if (year % 100 == 0) {
if (year % 400 == 0) {
System.out.println(year + " is a leap year.");
} else {
System.out.println(year + " is not a leap year.");
}
} else {
System.out.println(year + " is a leap year.");
}
} else {
System.out.println(year + " is not a leap year.");
}
}
}Output
Enter a year : 2012
2012 is a leap year.
