Hello,

Try the following code to check whether the year is leap year or not.

public class CheckLeapYear {
public static void main (String[] args) {

// The year to check for leapiness.
int year = 1998; // chenge year what u want to check.

// Check for a 2 digit year and adjust the year
// using a windowing technique. If the date has
// more than 2 digits we'll assume it is a complete
// year.
if (year < 100) {
// If the year is greater than 40 assume it
// is from 1900's. If the year is less than
// 40 assume it is from 2000's.
if (year > 40) {
year = year + 1900;
}
else {
year = year + 2000;
}
}

// Is theYear Divisible by 4?
if (year % 4 == 0) {

// Is theYear Divisible by 4 but not 100?
if (year % 100 != 0) {
System.out.println(year + " is a Leap year.");
}
// Is theYear Divisible by 4 and 100 and 400?
else if (year % 400 == 0) {
System.out.println(year + " is a Leap year.");
}
// It is Divisible by 4 and 100 but not 400!
else {
System.out.println(year + " is not a Leap year.");
}
}
// It is not divisible by 4.
else {
System.out.println(year + " is not a Leap year.");
}
}
}

Hi friend,

import java.io.*;
import java.text.*;

public class LeapYearDemo {
public static void main (String[] args) throws IOException {
int theYear;
System.out.print("Enter the year: ");
if (theYear < 100) {
if (theYear > 40) {
theYear = theYear + 1900;
}
else {
theYear = theYear + 2000;
}
}
// Is theYear Divisible by 4?
if (theYear % 4 == 0) {

// Is theYear Divisible by 4 but not 100?
if (theYear % 100 != 0) {
System.out.println(theYear + " is a leap year.");
}
// Is theYear Divisible by 4 and 100 and 400?
else if (theYear % 400 == 0) {
System.out.println(theYear + " is a leap year.");
}
// It is Divisible by 4 and 100 but not 400!
else {
System.out.println(theYear + " is not a leap year.");
}
}
else {
System.out.println(theYear + " is not a leap year.");
}
}
}
