Exception in thread "main" java.time.temporal.UnsupportedTemporalTypeException: Unsupported unit: Seconds

Asked on December 02, 2018
I am trying to run plus(TemporalAmount amountToAdd) of LocalDate class.
LocalDate localDate1 = LocalDate.now();
LocalDate localDate2 = localDate1.plus(Duration.ofDays(10));
System.out.println(localDate2);
But getting error.

at java.base/java.time.Duration.addTo(Duration.java:1102)
at java.base/java.time.LocalDate.plus(LocalDate.java:1174)
Why?

Use Period instead of Duration.
LocalDate localDate2 = localDate1.plus(Period.ofDays(15));
And it will work.
Duration
A Duration is most suitable in situations that measure machine-based time, such as code that uses an Instant object.
Period
To define an amount of time with date-based values (years, months, days), use the Period class.
