SimpleDateFormat.formatImpl介绍

[英]Formats the date.

If the FieldPosition field is not null, and the field specified by this FieldPosition is formatted, set the begin and end index of the formatted field in the FieldPosition.

If the list fields is not null, find fields of this date, set FieldPositions with these fields, and add them to the fields vector.
[中]格式化日期。
如果FieldPosition字段不为空，并且此FieldPosition指定的字段已格式化，请在FieldPosition中设置格式化字段的开始和结束索引。
如果列表字段不为空，则查找此日期的字段，使用这些字段设置字段位置，并将它们添加到字段向量中。
