What is wrong?

Question about the task

Under discussion

Code does exactly what is being requested.....

1. Implement the isDateOdd(String date) method so that it returns true if the number of days since the beginning of the year is odd, and otherwise returns false
2. String date is passed in the form: FEBRUARY 1 2013
Don't forget to account for the first day of the year.

Example:
JANUARY 1 2000 = true JANUARY 2 2020 = false

Requirements:

The program should display text on the screen.
The Solution class must have two methods.
The isDateOdd() method must return true if the number of days since the beginning of the year is odd, and must otherwise return false.
The main() method should call the isDateOdd() method.

package com.codegym.task.task08.task0827; import java.time.LocalDate; import java.time.format.DateTimeFormatter; import java.time.temporal.ChronoUnit; /* Working with dates */ public class Solution { public static void main(String[] args) throws Exception{ System.out.println(isDateOdd("May 1 2013")); } public static boolean isDateOdd(String date) throws Exception{ DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MMM d yyyy");//formats string into a date LocalDate day1 = LocalDate.parse(date, formatter); int dayNum = day1.getDayOfYear(); if (dayNum % 2 != 0) {return true;} return false; } }

You are counting days only in 2013 year.

I tried each adjustment but none resulting in verification.

Two problems... if you're not systems default localisation isn't english, then 'May' probably won't get detected. So you need to set that as Vincenzo already suggested (or use US). Next is your parse pattern. MMM will look for short month names like JUN, JAN, AUG. So use MMMM for full month names. Btw.: dayNum % 2 != 0 already results in a boolean so there is no need to check that again with an if clause and you can do smth. like that:

return dayNum % 2 != 0;

Hi, if i run your code in my ide, it throws a DateTimeParseException. After fitting in "Locale.ENGLISH" DateTimeFormatter.ofPattern("MMM d yyyy", Locale.ENGLISH) it works

I tried that as well and still did not pass verification.

Ok, I solved it in another way with SimpleDateFormat . You can try this:

if (dayNum % 2 != 0)
    return true;
else
    return false;
