# Number of days in the year

• 8
• Locked
On Earth, a year lasts 365 or 366 days. The number of days is calculated according to the following formula: A leap year (366 days) is every year evenly divisible by 4, except for years that are multiples of 100 but not multiples of 400. We'll write a program that will determine whether the user has entered a leap-year or ordinary year from the keyboard.

It can be solved without the operator % hint: when int a can be evenly divisible by int b, a==(a/b)*b.Then you can nail it with if/else!

Number of days in the year: x , where x is 366 for a leap year, and x is 365 for an ordinary year. all this means is they want you to hard-code the numbers in! I was putting a variable x and x++, thus failing the test over and over again! what a STUPID waste of time! :/

I created code to perform all the functions, however, I was leaving off the #4 task. The line of code that covered "all the remaining years"

For some reason, the help section won't accept my question. Can anyone help me out here? The third requirement is not met. 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 { BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in)); String y = bufferedReader.readLine(); int a = Integer.parseInt(y); int leap400 = a % 400; int nonLeap = a % 100; int leap4 = a % 4; if (a == leap400) { System.out.println("Number of days in the year: 366"); } else if (a == nonLeap) { System.out.println("Number of days in the year: 365"); } else if (a == leap4) { System.out.println("Number of days in the year: 366"); } else { System.out.println("Number of days in the year: 365"); } } }

You received the recommendation "Check the solution with different input values, for example: 1988"! Your solution says "Number of days in the year: 365" for 1988. But 1988 is a leap year and has 366 days!

Third requirement not met. They don't allow me to post my question in the help section. It says "Invalid request argument"

Every year that is evenly divisible by 4 is a leap year, unless they are evenly divisible by 100, in which case they also need to be evenly divisible by 400.

This is exactly the math explanation I needed, thanks

This Statement "if the year is evenly divisible by 400, then it is a leap year" is false coz 2004 / 400 = 5.01

But it's still divisible by 4.

follow the steps from the hint it is very helpful.e.g. 4 steps then use 4 if else statements.
