Instant.get介绍

[英]Gets the value of the specified field from this instant as an int.

This queries this instant for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The #isSupported(TemporalField) will return valid values based on this date-time, except INSTANT_SECONDS which is too large to fit in an int and throws a DateTimeException. All other ChronoField instances will throw a DateTimeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor)passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
[中]从该瞬间获取指定字段的int值。
这将立即查询指定字段的值。返回的值将始终在字段的有效值范围内。如果由于字段不受支持或其他原因而无法返回值，则会引发异常。
如果该字段是一个ChronoField，则在此处实现查询。#isSupported（TemporalField）将基于此日期时间返回有效值，但INSTANT_SECONDS除外，该值太大，无法容纳int并引发DateTimeException。所有其他ChronoField实例将引发DateTimeException。
如果字段不是ChronoField，则通过调用TemporalField获得此方法的结果。getFrom（临时Accessor）将此作为参数传递。是否可以获得该值以及该值表示的内容由字段决定。
