How to get the Year of a Temporal in Java

My problem is to find a useful method from the Temporal interface. In specific, I want to have the year from an Object, which is implementing the Temporal interface. All methods of the interface just add or sub from the objects, however, I just want to get the year of the Temporal itself.

The Temporal interface inherits the TemporalAccessor::get method, so for example you can do this:

Temporal t = LocalDate.now();
System.out.println(t.get(ChronoField.YEAR));

Output:

2018

EDIT

As @Ole V.V. pointed out is good to validate if the Temporal implementation supports the desired field using Temporal::isSupported:

if(t.isSupported(ChronoField.YEAR)){
   // ...
}

This will prevent getting exceptions if the Temporal implementation doesn't support the desired field. For example, Instant is a Temporal implementation that doesn't support the Year.

its defined in its superInterface TemporalAccessor.

so you can get the year by,

int year = temporal.get(ChronoField.YEAR);
