Hi,

The java.time.temporal.TemporalAdjusters are not mentioned in the book. Do you think they will be included in the material?
It's not bad to know them...but there are a lot of new things to remember about the dates...

Only one person reported getting a simple question on it. So I would say if you just go through our questions on this, you will be fine. No need to read further.

Hi,

Thank you for the quick answer. I will go through the exercises again.
I am struggling with the following code which appears in the book at page 149 (at least this is the page using Kindle Cloud Reader)
Could you please have a look at it?

DateTimeFormatter f = DateTimeFormatter.ofPattern("MM dd YYYY");
LocalDate date1 = LocalDate.parse("01 02 2015", f);
System.out.println(date1);

It gives the following error:
Exception in thread "main" java.time.format.DateTimeParseException: Text '01 02 2015' could not be parsed: Unable to obtain LocalDate from TemporalAccessor: {WeekBasedYear[WeekFields[SUNDAY,1]]=2015, MonthOfYear=1, DayOfMonth=2},ISO of type java.time.format.Parsed

Do you have any idea why? Thanks

PS: I did not know if for questions like this (related only to a certain exercise by topic) I should start a new topic on the forum or just write here. Thanks

Your formatter is for date+time but you are trying to parse a string that contains only date.

Hi,

Thank you, I did not realize that
I'll try again using only the date formatter.

Only one person reported getting a simple question on it.

Is this person real, 'cause I rather not learn on something out-of-scope that is as captivating as this,
especially at exam 6 of 7, having a TON of things currently in mind.

If you'd say it's one person out of 3000, I'd skip this topic so fast the page will have tire fire on it.

The person is certainly real.

Sure, that is a decision that you should make based on your bandwidth.

You can skip it but if I were you, I would spend may be about 10-15 minutes on it.

HTH,

The question is :
You want to print the date that represents upcoming tuesday from now even if the current day is a tuesday. Which of the following lines of code accomplishe(s) this?

Why is it using System.out.println(LocalDate.now().with(TemporalAdjusters.next(DayOfWeek.TUESDAY)));

Should it be
System.out.println(LocalDate.now().with(TemporalAdjusters.nextOrSame(DayOfWeek.TUESDAY))); ? because should return today if today is Tuesday ?

No, the problem statement want to print the next Tuesday (not today even if today is a tuesday).

I am struggling with the following code which appears in the book at page 149 (at least this is the page using Kindle Cloud Reader)

Your formatter is for date+time but you are trying to parse a string that contains only date.

"YYYY" in uppercase isn't working: Y = week-based-year
"yyyy" in lowercase is the correct one for parsing above String: y = year-of-era

Are TemporalAdjusters relevant for the exam? The answer about this is 4 years old.
Have there been any recent reports of people getting it?

No, but I would still go though the information given in this question. You might be the lucky/unlucky one who gets that one question.
