Please help...have been struggling here for over 3 hours..

Question about the task

Resolved

com/codegym/task/task08/task0827/Solution.java:24: error: unreported exception java.text.ParseException; must be caught or declared to be thrown Date dd = new SimpleDateFormat("MMMM d yyyy").parse(s); Why is that not compiling...million thanks in advance!

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.util.Date; import java.text.SimpleDateFormat; import java.util.*; /* Working with dates */ public class Solution { public static void main(String[] args) { System.out.println(isDateOdd("MAY 1 2013")); } public static boolean isDateOdd(String date) { //Converting the date format from "MAY 1 2013" to "May 1 2013", tested, np at all. char[] list = date.toCharArray(); for (int i=1; list[i] != ' '; i++) list[i] = Character.toLowerCase(list[i]); String s = new String(list); //The only problem lays here: parsing the string into date, // which I totally don't understand why it's not working, crying for help! Date dd = new SimpleDateFormat("MMMM d yyyy").parse(s); //Making the odd-day to true and even-day to false, tested, np at all dd.setYear(70); int value = (int) (dd.getTime() / (1000*3600*24)); return (value%2 == 0); } }

Thanks Patryk. Spent all day on this one. Had it all but the formatting shown below for clarity.

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
        .parseCaseInsensitive()
        .appendPattern("MMMM d yyyy")
        .toFormatter(Locale.ENGLISH);

Did hours of research on different Java time/date classes. I actually got it working correctly for the given date, but the validator stated it must work for other dates as well, even though that was NOT stated in the Requirements. Anyway, thanks!

solution

This code may be helpful, I really struggled with this task, but in the end i think i found good solution. Enjoy!

import java.text.ParseException;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
import java.time.format.DateTimeFormatterBuilder;
import java.util.Locale;

/*
Working with dates

*/

public class Solution {
    public static void main(String[] args) throws ParseException {
        System.out.println(isDateOdd("JANUARY 13 2013"));
    }

    public static boolean isDateOdd(String date) {

        DateTimeFormatter formatter = new DateTimeFormatterBuilder()
                .parseCaseInsensitive()
                .appendPattern("MMMM d yyyy")
                .toFormatter(Locale.ENGLISH);

        LocalDate localDate = LocalDate.parse(date, formatter);
//        System.out.println(localDate);

        int dayNumber = localDate.getDayOfYear();
//        System.out.println(dayNumber);
        if (dayNumber % 2 == 0){
            return false;
        }
        else return true;
    }
}

Hi Patryk, Thanks for the solution. I don't get how I would have figured this out, given that we didn't learn it here. I know they encourage you to read elsewhere to come up with solutions, so I'm wondering where you got this info so I can also learn it? Thanks!

unreported exception java.text.ParseException; must be caught or declared to be thrown You should "caught" the exception (try-catch) "or declared to be thrown" the exception in the isDateOdd method signature (throws ...) :)
