Below program illustrate the java.util.GregorianCalendar.isLeapYear() function in Java :
Program 1:
Java
// Java Program to illustrate isLeapYear() function // of GregorianCalendar import java.io.*;import java.util.*; class GFG { public static void main(String[] args) { // Create a new calendar GregorianCalendar c = (GregorianCalendar) GregorianCalendar.getInstance(); // Display the current date and time System.out.println("Current Date and Time : " + c.getTime()); int year = c.get(GregorianCalendar.YEAR); if(c.isLeapYear(year)) { System.out.println(year + " is leap year"); } else { System.out.println(year + " is Not a leap year"); } }} |
Output:
Current Date and Time : Fri Jul 27 11:53:39 UTC 2018 2018 is Not a leap year
Program 2:
Java
// Java Program to illustrate isLeapYear() function // of GregorianCalendar import java.io.*;import java.util.*; class GFG { public static void main(String[] args) { // Create a new calendar GregorianCalendar c = (GregorianCalendar) GregorianCalendar.getInstance(); // Display the current date and time System.out.println("" + c.getTime()); // Modifying the current calendar c.add((GregorianCalendar.MONTH), -30); int year = c.get(GregorianCalendar.YEAR); if(c.isLeapYear(year)) { System.out.println(year + " is leap year"); } else { System.out.println(year + " is Not a leap year"); } }} |
Output:
Fri Jul 27 11:53:41 UTC 2018 2016 is leap year
