Why does an error occur when converting String to LocalTime?

Question

Kotlin

The following code throws an exception: Exception in thread "main" java.time.format.DateTimeParseException: Text '8:20:35' could not be parsed at index 0

val time = "8:20:35"
val localTime = LocalTime.parse(time)

I tried to pass the formatter there - it does not help:

val time = "8:20:35"
val formatter = DateTimeFormatter.ofPattern("HH:mm:ss", Locale.getDefault())
val localTime = LocalTime.parse(time, formatter)

Answer 1

Because your string does not comply with ISO-8601, it should not be "8", but "08"
val time = "08:20:35"
Here is the documentation
