Working with dates

Geniunely curious why this doesn't pass: I won't post all the code. But assume that the heavy lifting is done and the dates are parse correctly. LocalDate d1 = LocalDate.parse(str, formatter); LocalDate d2 = LocalDate.parse(newYears, formatter); long daysBetween = java.time.temporal.ChronoUnit.DAYS.between(d2, d1); return daysBetween % 2 == 0 ? true : false;

the actual solution was not long or complicated, but there are so many different ways to get at this problem, it was very time-consuming. Solved it by using Date to store the parameter and using it to set the Calendar time to get the DAY_OF_YEAR. Gonna have to do more task to get better at doing the date, calendar thing. Happy coding! :)

Here is a tutorial on parsing String to Date that I found incredibly useful in solving this project: https://howtodoinjava.com/java/date-time/java-parse-string-to-date/ Couple that with CodeGym tutorial on this exact problem: https://codegym.cc/quests/lectures/questsyntax.level08.lecture04

JANUARY 1 2000 = true JANUARY 2 2020 = false If the requirement is to return true if the number of days since the beginning of the year is odd, then January 2 2020 should return true because it is 1 (odd) day since the beginning of the year. January 1 2020 is an understandable exception.

Determine how many days have passed since the beginning of the year: https://codegym.cc/quests/lectures/questsyntax.level08.lecture04

Tip: Clone the date object that you initialized by parsing the String parameter. Date newYear = new Date(passedDate.clone().toString()); Set the month and date to 0(Jan) and 1. No need to set the year. Number of days passed since new year = differenceInMilliseconds/(1000*60*60*24) + 1

Hint: you can set a date to the beginning of the year and increase this in a loop by BeginningOfTheYearDate.setDate(BeginningOfTheYearDate.getDate()+1) . If you do so until it is the same as the input date and keep track of the times you increased the date you can easily determine if the days passed are odd or even.

I am currently working on one of your exercises and somehow the Calendar.MONTH isn't working. The Compiler is telling me, that there is no constructor for GregorianCalendar(int,java.lang.String,int). Only java.util.GregorianCalendar.GregorianCalendar(int,int,int). So I guess I will have to write a little method to transform the Month-Word into the corresponding number... Maybe someone can tell me, why Calendar.MONTH isn't working? Am I needed to import another class? Currently I have util.Date; util.Calendar and util.GregorianCalendar; Update: because of the requirement that the Solution class must have two methods, I now have to take everything I have outsorced into my transformMonth method and have to throw it in the isDateOdd method, and everything will be totally incomprehensible

Brutal. Couldn't solve it on my own. Had to look at the help section.
