Create a new class with name Chk_leapyear: 

import java.util.Scanner;

public class Chk_leapyear {
   
    public static void main(String[] args) {
        // TODO Auto-generated method stub
       
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a year to check if it is leap year : ");
        int year = sc.nextInt();
        System.out.println("You entered : "+year);
        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{
            if(year%4==0)
                System.out.println(year+" is a leap year");
            else
