Checking for a Leap Year using GregorianCalendar in Java
The GregorianCalendar.isLeapYear() method determines if the given year is a leap year. Returns true if the given year is a leap year.
Firstly, import the following package to work with GregorianCalendar class.
import java.util.GregorianCalendar;
Now, check for a year by adding it as a parameter in the isLeapYear() method.
gcal.isLeapYear(2012)
The following is an example.
Example
import java.text.ParseException;
import java.util.GregorianCalendar;
public class Demo {
public static void main(String[] args) throws ParseException {
GregorianCalendar gcal = new GregorianCalendar();
System.out.println("Is it a leap year? "+gcal.isLeapYear(2012));
}
}Output
Is it a leap year? true
Let us see another example.
Example
import java.text.ParseException;
import java.util.GregorianCalendar;
public class Demo {
public static void main(String[] args) {
GregorianCalendar calendar = (GregorianCalendar) GregorianCalendar.getInstance();
System.out.println("Current date-time = " + calendar.getTime());
boolean res = calendar.isLeapYear(calendar.get(GregorianCalendar.YEAR));
System.out.println("Is it a leap year? " + res);
}
}Output
Current date-time = Mon Nov 19 15:45:30 UTC 2018 Is it a leap year? false
