DateTimeFormatter can not parse date with decimal 0 after second in Java 8

I am using Java 8. I am trying to parse a date to string with DateTimeFormatter. But it gives the following error. My attempt and error are given below.

My code:

String getFormatedDateForList(String dateObj) {
    // dateObj = "2019-02-06 00:00:00.0"
    DateTimeFormatter inputFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
    DateTimeFormatter outputFormat = DateTimeFormatter.ofPattern("dd/MM/yyyy");
    String output = LocalDate.parse(dateObj, inputFormat).format(outputFormat)
    return output
}

Error:

Text '2019-02-06 00:00:00.0' could not be parsed, unparsed text found at index 19. Stacktrace follows: Message: Text '2019-02-06 00:00:00.0' could not be parsed, unparsed text found at index 19

Answer

Your input formatting pattern yyyy-MM-dd HH:mm:ss specifies the first 19 characters, while your input dateObj contains more than that. Hence the parser finds unparsed text from the 20th character (index 19) onwards.

Given you have a tenth of a second in dateObj, you need to specify that in your formatting pattern. Based on the API, I think you want:

yyyy-MM-dd HH:mm:ss.S
