JavaScript current date plus (day, week, month, year)
The code is as follows://create the date var myDate = new Date(); //add a day to the date myDate.setDate(myDate.getDate() + 1); //add a week myDate.setDate(myDate.getDate() + 7); / /add a month myDate.setMonth(myDate.getMonth() + 1); //add a year myDate.setYear(myDate.getYear() + 1);

Extract day, month, year from YYYY-DD-MM string in Javascript
I YYYY-DD-MM found the best solution to extract day, month, year from a string in Javascript: Excerpt from: 2019-25-01 Objection: { day: 25, month: 01, year: 2019 } What is the best way. Thanks in advance! 1> Nina Scholz..: You can split, deconstruct and Return a new object. const getDate = string => (([year, day, month]) => ({ day, month, year }))( string.split(‘-‘)); console.log(getDate(‘2019-25-01’));
Java example – get year, month, etc.
The following example demonstrates how to use the Calendar class to output the year, month, etc.: /* author by w3cschool.cc File name: Main.java */import java.util.Calendar;public class Main { public static void main(String[] args) { Calendar cal = Calendar .getInstance(); int day = cal.get(Calendar.DATE); int mOnth= cal.get(Calendar.MONTH) + 1; int year = cal.get(Calendar.YEAR); int dow = cal.get( Calendar.DAY_OF_WEEK); int dom = cal.get(Calendar.DAY_OF_MONTH); int doy = cal.get(Calendar.DAY_OF_YEAR); System.out.println(“Current time: ” + cal.getTime()); System. out.println(“Date: ” + day); System.out.println(“Month: ” + month); System.out.println(“Year: ” + year); System.out.println(“Day of the week Days: ” + dow); // Sunday is the first day of the week and the output is 1, Monday is 2, and so on System.out.println(“The number of days in January: ” + Come to 2 sources gaodaima#com ([email protected]&网 dom); System.out.println(“Day of the year: ” + doy); }} The output result of running the above code is: Current time: Fri Mar 27 21:44:15 CST 2015 date: 27 month: 3 year: 2015 day of the week: 6 day of month: 27 year Day: 86 The above is the Java example – getting the year, month, etc., please pay attention to (www.gaodaima.com) for more related content!
Java date conversion SimpleDateFormat format (year, month, day, hour, minute and second)
24-hour time display: import java.util.Date; public class DateTest { /*** @param args*/public static void main(String[] args) { Date current = new Date();java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(“yyyy-MM-dd HH:mm:ss “);String time = sdf.format(current);System.out.println(time);} } For 12-hour format, just change HH:mm:ss is changed to hh:mm:ss
Java gets the current year, month, day, hour, minute, second, etc.
Calendar cal = Calendar.getInstance(); // Current year int year = cal .get(Calendar.YEAR); // Current month int mOnth= cal .get(Calendar.MONTH) + 1; // Current day int day = cal .get(Calendar.DATE); // Current hour int hour = cal .get(Calendar.HOUR_OF_DAY); // Current minute int minute = cal .get(Calendar.MINUTE); > // Current second int secOnd= cal .get(Calendar.SECOND); System.out.println(year + “year” + month + ” month” + day + “日” + hour + “hour” + minute + “minute” + second + “second”); // The current is The day of the week int dayOfWeek = cal .get(Calendar.DAY_OF_WEEK); // The current day of the month int dayOfMOnth= cal .get(Calendar.DAY_OF_MONTH); // The current day of the year int dayOfYear = cal .get(Calendar.DAY_OF_YEAR); SimpleDateFormat format = new SimpleDateFormat(” yyyy-MM-dd”); // The first day of the month cal = Calendar.getInstance(); cal .add(Calendar.MONTH, 0); cal .set(Calendar.DAY_OF_MONTH, 1); String firstday = format.format(cal .getTime()); System.out.println(“this The first day of the month is: ” + firstday ); // The last day of the month cal = Calendar.getInstance(); cal .add(Calendar.MONTH, 1); cal .set(Calendar.DAY_OF_MONTH, 0); String lastday = format.format(cal .getTime()); System.out.println(“The last day of this month is: ” + lastday); / / Obtain through Date objectSimpleDateFormat format = new SimpleDateFormat(“yyyy-MM-dd hh:mm:ss”);Date date = new Date(); System.out.println(“current…
