Formatting a date time string

I have the following date which we get from an API 2022-11-23 06:12:31

I am wondering if my approach is the best.

And I need to display in this format 23 November 2022

I am using substringbefore to remove the time portion so I am left with the following: "2022-11-23"

I am using org.threeten.bp

val DAY_MONTH_YEAR_DISPLAY_FORMATTER =
    DateTimeFormatter.ofPattern("dd MMMM yyyy").withZone(ZoneOffset.systemDefault())

fun formatAsFullMonthDisplayDate(localDateTime: String): String {
    return try {
        LocalDate.parse(localDateTime.substringBefore(" "), DAY_MONTH_YEAR_DISPLAY_FORMATTER).buildDate()
    } catch (ignored: Exception) {
        ""
    }
}

private fun LocalDate.buildDate(): String {
    return buildString {
        append(this@buildDate.dayOfMonth)
        append(" ")
        append(this@buildDate.month)
        append(" ")
        append(this@buildDate.year)
    }
}

You can try this:

val inputDate = "2022-11-23 06:12:31"
val outputFormat = "dd MMMM yyyy"
val inputFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
val outputFormatter = DateTimeFormatter.ofPattern(outputFormat)

val date = LocalDateTime.parse(inputDate, inputFormat)
val formattedDate = date.format(outputFormatter)

println(formattedDate) // "23 November 2022"
