java.util.Date#getSeconds ( )源码实例Demo

/**
 * Constructs a LocalDateTime from a <code>java.util.Date</code>
 * using exactly the same field values.
 * <p>
 * Each field is queried from the Date and assigned to the LocalDateTime.
 * This is useful if you have been using the Date as a local date,
 * ignoring the zone.
 * <p>
 * One advantage of this method is that this method is unaffected if the
 * version of the time zone data differs between the JDK and Joda-Time.
 * That is because the local field values are transferred, calculated using
 * the JDK time zone data and without using the Joda-Time time zone data.
 * <p>
 * This factory method always creates a LocalDateTime with ISO chronology.
 *
 * @param date  the Date to extract fields from, not null
 * @return the created local date-time, not null
 * @throws IllegalArgumentException if the calendar is null
 * @throws IllegalArgumentException if the date is invalid for the ISO chronology
