Data and Time Format. A formatting string describes how a date/time values should be read and written from (to) string representation (flat files, human readable output, etc.). A format can also specify an engine which CloudConnect will use by specifying a prefix (see below). There are two built-in date engines available: standard Java and 3. A SimpleDateFormat, as its name indicates, formats Date s. Not a Calendar. So, if you want to format a GregorianCalendar using a SimpleDateFormat, you must convert the Calendar to a Date first: dateFormat.format (calendar.getTime ()); And what you see printed is the toString () representation of the calendar. Use the java.Util.Date Class to Get the Current Year in Java. The getYear () method present in the java.util.Date class can be used to get the current year in the older versions of JDK, which is now replaced with the Calendar.get (Calendar.YEAR) method. This method is used to return the value by subtracting 1900 from the current date object. The ofYearDay (int year, int dayOfYear) method of LocalDate class in Java is used to obtain an instance of LocalDate from an input year and day-of-year. Here no value of the month is passed. The passed year forms the year of the instance and the day and month are calculated on the basis of dayOfYear. Here 1st January forms the starting day. 7. Library Management System. Learning Management System, this project build on Java is a great way to update the record, monitor and add books, search for the required ones, taking care of the issue date and return date. It comes with basic features like creating a new record and updating and deleting it. I need to find the first day of the last week of a year using Java 8 Date and Time API (java.time) and finally came to this solution: LocalDate date = LocalDate.of(2016, 2, 17); LocalDate lastWeek .
