import java.util.GregorianCalendar;

public class GregorianCalendarDemo {
   public static void main(String[] args) {

      // create a new calendar
      GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();

      // print the current date and time
      System.out.println("" + cal.getTime());

      // get weeks available in the YEAR
      System.out.println(cal.getWeeksInWeekYear());
   }
}

package com.tutorialspoint;

import java.util.GregorianCalendar;

public class GregorianCalendarDemo {
   public static void main(String[] args) {

      // create a new calendar
      GregorianCalendar cal = (GregorianCalendar) GregorianCalendar.getInstance();

      // print the current date and time
      System.out.println("" + cal.getTime());

      // subtract 2 years 
      cal.add((GregorianCalendar.YEAR), -2);

      // get weeks available in the YEAR
      System.out.println(cal.getWeeksInWeekYear());
   }
}

Output

Let us compile and run the above program, this will produce the following result −
