dayofweek

问题 For example, in the case of 03/27/2016 to 04/02/2016, the dates fall in different months. var curr = new Date; // get current date var first = curr.getDate() - curr.getDay(); var last = first + 6; // last day is the first day + 6 var firstday = new Date(curr.setDate(first)).toUTCString(); var lastday = new Date(curr.setDate(last)).toUTCString(); 回答1: The getDay method returns the number of the day in the week, with Sunday as 0 and Saturday as 6. So if your week starts on Sunday, just subtract

问题 I tried the below code but it gives me the name of the day of week two days ago. DatePicker picker; int date = picker.DayOfMonth; int month = (picker.Month + 1);//month is 0 based int year = picker.Year; SimpleDateFormat simpledateformat = new SimpleDateFormat("EEE"); Date dt = new Date(year, month, date); 回答1: First convert your Date in to specific Date format using SimpleDateFormat Use SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEEE"); to get Day name in week WHERE EEEE ->

问题 In Java 8, what I found is TemporalAdjuster temporal = dayOfWeekInMonth(1,DayOfWeek.MONDAY) gives the temporal for the first Monday of a month, and next(DayOfWeek.MONDAY) gives the next Monday after a specific date. But I want to find nth MONDAY after specific date. For example, I want 2nd MONDAY after 2017-06-06 and it should be 2017-06-19 where dayOfWeekInMonth(2,DayOfWeek.MONDAY) will give me 2017-06-12 and next(DayOfWeek.MONDAY) has of course no parameter for the nth DayOfWeek's indicator

问题 Assuming the following code... Instant x = Instant.now(); How do I get day of week from x? 回答1: You have to convert it to ZonedDateTime Instant.now().atZone(ZoneId.systemDefault()).getDayOfWeek() 回答2: I have awarded points to techtabu, but I ended up using atOffset instead. Here is where I ended up... int currentDayOfWeekValue = Instant.now().atOffset(ZoneOffset.UTC).getDayOfWeek().getValue(); I am amazed how difficult the Java8 datetime libraries are. There are so many variations of similar

问题 I'm porting an existing application from Joda-Time to Java 8 java.time . I ran into a problem where parsing a date/time string that contains a 'day of week' value triggered an exception in my unit tests. When parsing: 2016-12-21 20:50:25 Wednesday December +0000 3 using format: yyyy'-'MM'-'dd' 'HH':'mm':'ss' 'EEEE' 'MMMM' 'ZZ' 'e I get: java.time.format.DateTimeParseException: Text '2016-12-21 20:50:25 Wednesday December +0000 3' could not be parsed: Conflict found: Field DayOfWeek 3 differs

问题 What is wrong with the below code? It gives wrong day for any date of the year. import java.util.Scanner; import java.util.Calendar; public class Solution { public static String getDay(String d, String m, String y) { String[] days = {"SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY"}; Calendar c = Calendar.getInstance(); c.set(Integer.parseInt(y), Integer.parseInt(m), Integer.parseInt(d)); return days[c.get(Calendar.DAY_OF_WEEK) - 1]; } public static void main

问题 I've been trying to figure out how to take next available day based on Present day i.e., if today is Friday, then search in Array for the next nearest day like if Array values are 1[Monday], 2[Tuesday], 4[Thursday], 6[Saturday] then my next day should be Saturday. Here is what i tried //Here i'll get days like 0, 2, 3, 4, 6 pattern, and i'm spliting them based on comma to get single-single day value in array of string string[] GetDays = DayInWeek.Split(','); [Here day patterns will change
