can you see my wrong code?

package com.codegym.task.task04.task0414; /* Number of days in the year */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader bf=new BufferedReader(new InputStreamReader(System.in)); String numy =bf.readLine(); int numi=Integer.parseInt(numy) ; checkYear(numi); } public static void checkYear(int numi){ int y = numi%400 ; int x = numi%4 ; int z = numi%100; if ((x==0)||(y==0&&z!=0) ) System.out.println("Number of days in the year: "+366) ; else System.out.println("Number of days in the year:"+365) ; } }
