Java Program to Check Leap Year

What is  a Calendar class?

In this Article, we will write a Program to Check Leap Year in Java.
The Calendar class in the Java programming language is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week.

Calendar Class:

The Calendar class also provides a number of methods for adding or subtracting time from a calendar, such as add() and roll(), and for comparing two calendars.

Java Program to Check Leap Year:

import java.util.*;

public class Main{
    public static void main(String[] args){
        // Scanner class for taking input
        Scanner input = new Scanner(;
        System.out.print("Enter a year: ");
        int year = input.nextInt();
        // Initializing the answer variable
        boolean isLeapYear = false;

        if (year % 4 == 0) {
            if (year % 100 == 0) {
                if (year % 400 == 0) {
                    isLeapYear = true;
            } else {
                isLeapYear = true;

        if (isLeapYear) {
            System.out.println(year + " is a leap year.");
        } else {
            System.out.println(year + " is not a leap year.");


Enter a year: 1900


1900 is not a leap year.


In the above program,we first take input from the user for the year to be checked. Then, we use a series of if statements to check whether the year is divisible by 4, 100, and 400 to determine whether it is a leap year. Finally, we print out the result of whether the given year is a leap year or not.
