在Java 8中解析时钟时间

Question

我想知道是否有可能在Java 8中解析时钟时间:分钟:秒？

例如

final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
final String str = "12:22:10";
final LocalDateTime dateTime = LocalDateTime.parse(str, formatter);

我试过但得到这个例外:

Exception in thread "main" java.time.format.DateTimeParseException: Text '12:22:10' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {},ISO resolved to 12:22:10 of type java.time.format.Parsed

Answer 1

由于您只有时间使用LocalTime该类:

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
String str = "12:22:10";
LocalTime time = LocalTime.parse(str, formatter);
