SimpleDateFormat.parse介绍

[英]Parses a date from the specified string starting at the index specified by position. If the string is successfully parsed then the index of the ParsePosition is updated to the index following the parsed text. On error, the index is unchanged and the error index of ParsePosition is set to the index where the error occurred.
[中]从位置指定的索引处开始分析指定字符串中的日期。如果成功解析字符串，则ParsePosition的索引将更新为解析文本后面的索引。出错时，索引保持不变，ParsePosition的错误索引设置为发生错误的索引。
