Current time in HH:MM:SS with Java 8+ and DateTimeFormatterBuilder 📎

With the DateTimeFormatterBuilder you can directly specify the desired time format. The invocation of the method currentFormattedTime:


import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
import java.time.format.DateTimeFormatterBuilder;
import static java.time.temporal.ChronoField.HOUR_OF_DAY;
import static java.time.temporal.ChronoField.MINUTE_OF_HOUR;
import static java.time.temporal.ChronoField.SECOND_OF_MINUTE;
        
static String currentFormattedTime() {
    DateTimeFormatter timeFormatter = new DateTimeFormatterBuilder()
            .appendValue(HOUR_OF_DAY, 2)
            .appendLiteral(':')
            .appendValue(MINUTE_OF_HOUR, 2)
            .optionalStart()
            .appendLiteral(':')
            .appendValue(SECOND_OF_MINUTE, 2)
            .toFormatter();
    return LocalTime.now().format(timeFormatter);
}

will return the current time as e.g.: 07:37:12.
