Question

Here is my code which i am using to parse string using Instant.parse,

String date = "2018-05-01T00:00:00";
Instant.parse(date)

And getting below error

java.time.format.DateTimeParseException: Text '2018-05-01T00:00:00' could not be parsed at index 19
        at java.time.format.DateTimeFormatter.parseResolved0(DateTimeFormatter.java:1949)
        at java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1851)
        at java.time.Instant.parse(Instant.java:395)

I cannot use other then Instant so looking solution for it only!

Answer 1

Instant.parse will only accept the string that are in ISO INSTANT FORMAT

Obtains an instance of Instant from a text string such as 2007-12-03T10:15:30.00Z.

The string must represent a valid instant in UTC and is parsed using DateTimeFormatter.ISO_INSTANT.

But the String you have represents LocalDateTime , so parse it into LocalDateTime and then convert into Instant

A date-time without a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30.

LocalDateTime dateTime = LocalDateTime.parse(date);
Instant instant = dateTime.atZone(ZoneId.of("America/New_York")).toInstant();
