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.

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

at java.base/java.time.LocalDate.plus(LocalDate.java:1272)

at java.base/java.time.LocalDate.plus(LocalDate.java:139)

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.

To define an amount of time with date-based values (years, months, days), use the Period class.
