java.text.ParseException: Unparseable date: yyyy-MM-dd HH:mm:ss.SSSSSS

Question

I am getting ParseException for the following code

    String dateStr = \"2011-12-22 10:56:24.389362\";
    String formatStr = \"yyyy-MM-dd HH:m         


        

Answer 1

Your date input for milliseconds is incorrect. It should be:-

String dateStr = "2011-12-22 10:56:24.389";

You also do not need the extra number of "S"s in the pattern. The following should suffice:

String formatStr = "yyyy-MM-dd HH:mm:ss.S";

It is clearly mentioned in the java docs for presentation type of Number:

Number: For formatting, the number of pattern letters is the minimum number of digits, and shorter numbers are zero-padded to this amount. For parsing, the number of pattern letters is ignored unless it's needed to separate two adjacent fields.

It works when you set lenient to be true (or comment out the line which defaults it true) since you are asking the parser to be not strict about the parsing. From java docs on setLenient():-

Specify whether or not date/time parsing is to be lenient. With lenient parsing, the parser may use heuristics to interpret inputs that do not precisely match this object's format. With strict parsing, inputs must match this object's format.
