**Leap Year Program in Java:** A year is a **Leap Year** if it satisfies the following conditions:

- The year is
**exactly divisible by 400**(such as 2000,2400) or, - The year is
**exactly divisible by 4**(such as 2008, 2012, 2016) and not a**multiple of 100**(such as 1900, 2100, 2200).

Write a Java Program to check whether a given year is a leap year or not.

1. Take a year as input.

2. Check whether a given year is divisible by 400.

3. Check whether a given year is divisible by 100.

4. Check whether a given year is divisible by 4.

5. If the condition at step 2 and 4 becomes true, then the year is a leap year.

6. If the condition at step 3 becomes true, then the year is not a leap year.

Here is the source code of the Java Program to Find if a Given Year is a Leap Year. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

import java.util.Scanner; public class Check_Leap_Year { public static void main(String args[]) { Scanner s = new Scanner(System.in); System.out.print("Enter any year:"); int year = s.nextInt(); boolean flag = false; if(year % 400 == 0) { flag = true; } else if (year % 100 == 0) { flag = false; } else if(year % 4 == 0) { flag = true; } else { flag = false; } if(flag) { System.out.println("Year "+year+" is a Leap Year"); } else { System.out.println("Year "+year+" is not a Leap Year"); } } }

1. Enter any year as an input. We first whether the given year is divisible by 400 or not.

2. If it is divisible then it is a leap year else we check for further conditions.

3. Now if it is divisible by 100 then it is not a leap year or else we further divide it by 4.

4. If it is divisible then it is a leap year else its not.

**Testcase 1:** In this case, we enter the year “1800” as input to check whether a given year is leap year or not.

Enter any year: 1800 1800 is not a Leap Year

**Testcase 2:** In this case, we enter the year “2000” as input to check whether a given year is leap year or not.

Enter any year: 2000 2000 is a Leap Year
