Java GregorianCalendar - getActualMaximum() Method

The java.util.GregorianCalendar.getActualMaximum() method returns the maximum value that this calendar field could have, taking into consideration the given time value and the current values of the getFirstDayOfWeek, getMinimalDaysInFirstWeek, getGregorianChange and getTimeZone methods.

For example, if the date of this instance is February 1, 2004, the actual maximum value of the DAY_OF_MONTH field is 29 because 2004 is a leap year, and if the date of this instance is February 1, 2005, it's 28.

Syntax

public int getActualMaximum(int field)

Parameters

Return Value

Returns the maximum of the given field for the time value of this GregorianCalendar.

Exception

In the example below, the java.util.GregorianCalendar.getActualMaximum() method returns the maximum value for the given field for the given time.

import java.util.*;

public class MyClass {

    //creating a Calendar object with specified date
    GregorianCalendar Cal = new GregorianCalendar(2015, 1, 25);

    //printing the Calendar
    System.out.println("The Calendar is: " + Cal.getTime());

    //printing the actual maximum value for day_of_month
    int mon = Cal.getActualMaximum(GregorianCalendar.DAY_OF_MONTH);
