Java program to find if given year is leap year

import java.util.Scanner;
public class LeapYearDemo
{
   public static void main(String[] args)
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter any year: ");
      int year = sc.nextInt();
      boolean temp = false;
      if(year % 400 == 0)
      {
         temp = true;
      }
      else if(year % 100 == 0)

check leap year using time in java

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.Year;
import java.time.ZonedDateTime;
 
public class Main 
{
    public static void main(String[] args) 
    {
        // 1. ZonedDateTime
 
        ZonedDateTime currentTime = ZonedDateTime.now();
 
        if (currentTime.toLocalDate().isLeapYear()) 
        {
            System.out.println(currentTime.getYear() + " is a leap year");
        } else {
            System.out.println(currentTime.getYear() + " is NOT a leap year");
        }
 
        // 2. LocalDateTime
 
        LocalDateTime localDateTime = LocalDateTime.now();
 
        if (localDateTime.toLocalDate().isLeapYear()) 
        {
            System.out.println(localDateTime.getYear() + " is a leap year");
        } else {
            System.out.println(localDateTime.getYear() + " is NOT a leap year");
        }
         
        // 3. LocalDate
 
        LocalDate localDate = LocalDate.now();
 
        if (localDate.isLeapYear()) 
        {
            System.out.println(localDate.getYear() + " is a leap year");
        } else {
            System.out.println(localDate.getYear() + " is NOT a leap year");
        }
         
        //4. Check current year is leap year or not
 
        if (Year.now().isLeap()) 
        {
            System.out.println("Current year is a leap year");
        } else {
            System.out.println("Current year is NOT a leap year");
        }
