SimpleDateFormat.format介绍

[英]Formats the specified date as a string using the pattern of this date format and appends the string to the specified string buffer.

If the field member of field contains a value specifying a format field, then its beginIndex and endIndex members will be updated with the position of the first occurrence of this field in the formatted text.
[中]使用此日期格式的模式将指定的日期格式化为字符串，并将该字符串附加到指定的字符串缓冲区。
如果字段的字段成员包含指定格式字段的值，则其beginIndex和endIndex成员将更新为该字段在格式化文本中第一次出现的位置。
