localdate

I have a DateConverter class: public class DateConverter extends StringConverter<LocalDate> { String pattern = "EEE, dd. MM. uuuu"; DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern,Locale.US); @Override public String toString(LocalDate object) { try { return formatter.format(object); } catch(Exception ex) { return ""; } } @Override public LocalDate fromString(String string) { try { return LocalDate.parse(string, formatter); } catch(Exception ex) { return null; } } public String getPattern(){ return pattern; } } And I have this piece of code: allProd.forEach((prod) -> {

I am reading text and storing the dates as LocalDate variables. Is there any way for me to preserve the formatting from DateTimeFormatter so that when I call the LocalDate variable it will still be in this format. EDIT:I want the parsedDate to be stored in the correct format of 25/09/2016 rather than printing as a string My code: public static void main(String[] args) { LocalDate date = LocalDate.now(); DateTimeFormatter formatters = DateTimeFormatter.ofPattern("d/MM/uuuu"); String text = date.format(formatters); LocalDate parsedDate = LocalDate.parse(text, formatters); System.out.println(

I have stored in the DB this Time Frame: any day from 15:00 to 16:00 in LONDON (BST) I need to execute a program IF when I receive an event is between this Time Frame. I am running the Test now in Paris (16:22) where in London is 15:22 (so in between the Time Frame stored in the DB). SO this is my code // create Local Date Time from what I have stored in the DB LocalDateTime dateTime1 = LocalDateTime.of(2017, Month.JUNE, 15, 15, 00); LocalDateTime dateTime2 = LocalDateTime.of(2017, Month.JUNE, 15, 16, 00); Instant now = Instant.now(); System.out.println (now.isAfter (dateTime1.atZone(ZoneId.of

With Joda library, you can do DateTimeFormat.forPattern("yyyy").parseLocalDate("2008") that creates a LocalDate at Jan 1st, 2008 With Java8, you can try to do LocalDate.parse("2008",DateTimeFormatter.ofPattern("yyyy")) but that fails to parse: Text '2008' could not be parsed: Unable to obtain LocalDate from TemporalAccessor: {Year=2008},ISO of type java.time.format.Parsed Is there any alternative, instead of specifically writing sth like LocalDate.ofYearDay(Integer.valueOf("2008"), 1) ? LocalDate parsing requires that all of the year, month and day are specfied. You can specify default values

I´m trying to pase the next String using LocalDateTime, but I always get de unparsed text found error: Error java.time.format.DateTimeParseException: Text '2016-08-18 14:27:15.103+02' could not be parsed, unparsed text found at index 10 Here is my String: convertDate: ' 2016-08-18 14:27:15.103+02 ' And my code: public static LocalDate conversorStringToLocalDateTime(String convertDate) throws ParseException { LocalDate dateTime =LocalDate.parse(convertDate); return dateTime; } I guess is not too complicated, buy I´m not able to see the error. Could the +02 in the String be the cause? Basil

历史 早期，Java 对时间和日期的使用往往重度依赖 java.util.Date 和 java.util.Calendar 。 可惜的是，这2个api 本身不够健壮，有类似线程不安全等诸多问题，于是乎2000年左右，市面上出现了很多用于处理时间类的框架，如Joda-Time。 在Java 8 时代 官方为JDK开发新的时间/日期API的进程：JSR-310，启动了。于是就出现了新一套健壮的API。 Roadmap 新的API Java 8 中 新的API 包括了 5个包 java.time java.time.chrono java.time.format java.time.temporal java.time.zone java.time 是基础包，里面包含了 时间 日期的 基础类 如 LocalDate, LocalTime等 java.time.chrono 有点像linux 的守护进程 chronyd 用来访问不同的时间服务器。 java.time.format 顾名思义用来格式化和转换日期时间 java.time.temporal 可能也想不出好名字吧，里面都是些底层扩展类 java.time.zone 用来对各时区的支持 1. 时间线 Java8中 引入了时间线的概念，时间是连续不断，抽象成一条线，线上的点表示某一时刻。 一班来说，这个设定主要是面对机器的
