Java程序获得时间查询精度
要获得临时查询的精度，请使用TemporalQuery接口和TemporalQueries的precision()方法-
TemporalQuery<TemporalUnit>precision = TemporalQueries.precision(); Get the precision for LocalDate: LocalDate.now().query(precision) Get the precision for LocalTime: LocalTime.now().query(precision) Get the precision for YearMonth: YearMonth.now().query(precision) Get the precision for Year: Year.now().query(precision)
示例
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.Year;
import java.time.YearMonth;
import java.time.temporal.TemporalQueries;
import java.time.temporal.TemporalQuery;
import java.time.temporal.TemporalUnit;
public class Demo {
public static void main(String[] args) {
TemporalQuery<TemporalUnit>precision = TemporalQueries.precision();
System.out.println("TemporalQueries precision...");
System.out.println(LocalDate.now().query(precision));
System.out.println(LocalTime.now().query(precision));
System.out.println(LocalDateTime.now().query(precision));
System.out.println(YearMonth.now().query(precision));
System.out.println(Year.now().query(precision));
}
}输出结果
TemporalQueries precision... Days Nanos Nanos Months Years
