The static method removeTime() in the code snippet below will take a Date object as parameter and will return a new Date object where the hour, minute, second and millisecond information have been reset to zero. (Update: Here’s a link to a very similar example that also demonstrates the Java SimpleDateFormat class: How to get today’s date in Java.The following code snippet shows you how to remove time information from the object. Calendar tomorrow Calendar.getInstance () tomorrow.add (Calendar.DATE, 1) wakeuptime '05:00:00' Date datewakeuptime new SimpleDateFormat ('HH:mm:ss').parse (wakeuptime) Calendar calwakeuptime Calendar.getInstance () tTime (datewakeuptime) t (Calendar.HOUR, calwakeuptime. The setDate (String dateStr) method is so unreadable and splitting string with indexOf is so hard. I’ll add some more tutorials out here about using the Java Date and Calendar classes, including how to format dates, and perform date “math,” but for now, if you just need to get today’s date, I hope this helps. Java Date class and Calendar class with examples. Return value Changes the Date object in place, and returns its new timestamp. Try it Syntax setDate(dateValue) Parameters dateValue An integer representing the day of the month. instance it defaults to "today", or more accurately,Īs I write this article, the output from this class is: The setDate () method of Date instances changes the day of the month for this date according to local time. create a calendar instance, and get the date from that * A Java Date and Calendar example that shows how to A complete Java “get today’s date” exampleįor the sake of completeness - and to help you experiment - here’s the source code for a complete Java class which demonstrates this technique of getting today’s date (a “now” date): There are other ways to do this that are similar to this approach, but I believe this is the correct way to get an instance of today’s date, i.e., a date to represent “now”. Originally created for reports at Improvely, the Date Range Picker can be attached to any webpage element to pop up two calendars for selecting dates.

The Date class of java.util package implements Serializable, Cloneable and Comparable interface. ![]() Calendar c Calendar.getInstance () This returns a new Calendar instance set to the current time. ![]() From there you can set the Calendar instance to the date that you need. Java Code Example : This java example source code demonstrates the use of set () method of Calendar class. ![]() For example: 1 2 UtilDateModel model new UtilDateModel () tDate (1990, 8, 24) That sets the initial date to Septem(because in Java, the month number is zero-based). To create a new date, you will need a Calendar instance. This code can be read as, “Create an instance of a Java Calendar, which defaults to the current date and time then use the getTime method to convert this to a reference.” Setting initial date You can set the initial date for the calendar component when it is popped up. One is to set the instant parameter to a millisecond offset from the Epoch. The calendar is based on either the standard ISO-8601 chronology or any of the other chronology classes defined in the package. You can still get today’s date in Java using one line of code with the Java Calendar class, like this:ĭate today = Calendar.getInstance().getTime() There are two ways to set a Calendar to a date-time value. public class DatePicker extends ComboBoxBase < LocalDate > The DatePicker control allows the user to enter a date as text or to select a date from a calendar popup.Java Date/Calendar FAQ: How do I get an instance of today's date with Java?
