GregorianCalendar(int year, int month, int date)Ĭonstructs a GregorianCalendar with the given date set in the default time zone with the default locale. There are also several constructors for GregorianCalendar objects − Sr.No.Ĭonstructs a default GregorianCalendar using the current time in the default time zone with the default locale. These represent the two eras defined by the Gregorian calendar.
GregorianCalendar defines two fields: AD and BC.
The getInstance( ) method of Calendar returns a GregorianCalendar initialized with the current date and time in the default locale and time zone. We did not discuss Calendar class in this tutorial, you can look up standard Java documentation for this. GregorianCalendar is a concrete implementation of a Calendar class that implements the normal Gregorian calendar with which you are familiar. Long start = System.currentTimeMillis( ) The SimpleDateFormat class has some additional methods, notably parse( ), which tries to parse a string according to the format stored in the given SimpleDateFormat object. For more details, you can refer to Java Standard documentation. There are other useful classes related to Date and time. Nine-digit nanoseconds (with leading zeroes) Three-digit milliseconds (with leading zeroes) Two-digit hour (without leading zeroes), between 1 and 12 Two-digit hour (with leading zeroes), between 01 and 12 Two-digit hour (without leading zeroes), between 0 and 23 Two-digit hour (with leading zeroes), between 00 and 23 Three-digit day of year (with leading zeroes) Last two digits of the year (with leading zeroes)įirst two digits of the year (with leading zeroes) ("%s %tB % display time and date using toString() You can use a simple Date object with toString() method to print the current date and time as follows − Example This is a very easy method to get current date and time in Java. Sets the time and date as specified by time, which represents an elapsed time in milliseconds from midnight, January 1, 1970.Ĭonverts the invoking Date object into a string and returns the result. Returns a hash code for the invoking object. Returns the number of milliseconds that have elapsed since January 1, 1970. Returns true if the invoking Date object contains the same time and date as the one specified by date, otherwise, it returns false. Otherwise, it throws a ClassCastException. Operates identically to compareTo(Date) if obj is of class Date. Returns a positive value if the invoking object is later than date. Returns a negative value if the invoking object is earlier than date. Returns true if the invoking Date object contains a date that is earlier than the one specified by date, otherwise, it returns false.Ĭompares the value of the invoking object with that of date. Returns true if the invoking Date object contains a date that is later than the one specified by date, otherwise, it returns false. This constructor accepts an argument that equals the number of milliseconds that have elapsed since midnight, January 1, 1970.įollowing are the methods of the date class. This constructor initializes the object with the current date and time. The Date class supports two constructors as shown in the following table. Java provides the Date class available in java.util package, this class encapsulates the current date and time.
