Java Data Type - 如何获取Temporal的精确度

import java.time.LocalDate;
import java.time.LocalTime;
import java.time.YearMonth;
import java.time.temporal.TemporalQueries;
import java.time.temporal.TemporalQuery;
import java.time.temporal.TemporalUnit;

public class Main {

  public static void main(String[] args) {

    TemporalQuery<TemporalUnit> precision = TemporalQueries.precision();
    System.out.println(LocalDate.now().query(precision)); // Days
    System.out.println(LocalTime.now().query(precision)); // Nanos
    System.out.println(YearMonth.now().query(precision)); // Months

  }
}
