原文:https://www . geesforgeks . org/calendar-getactualmaximum-method-in-Java-with-examples/
calendar 类的getActualMaximum(intfield _ value)方法用于根据此 Calendar 的时间值返回指定日历字段可能具有的最大值。
语法:
public int getActualMaximum(int *field_value*)
参数:该方法取整数类型的一个参数 field_value ，指需要返回最大值的日历。
返回值:该方法返回传递字段的最大值。
下面的程序说明了日历类 getActualMaximum()方法的工作:
例 1:
// Java Code to illustrate
// getActualMaximum() Method
import java.util.*;
public class CalendarClassDemo {
public static void main(String args[])
{
// Creating a calendar
Calendar calndr
= Calendar.getInstance();
// Getting the maximum value that
// year field can have
int yr
= calndr.getActualMaximum(Calendar.YEAR);
System.out.println("The Maximum year: "
+ yr);
// Getting the maximum value that
// month field can have
int mon
= calndr.getActualMaximum(Calendar.MONTH);
System.out.println("The Maximum Month is: "
+ mon);
}
}
Output:
The Maximum year: 292278994
The Maximum Month is: 11
例 2:
// Java Code to illustrate
// getActualMaximum() Method
import java.util.*;
public class CalendarClassDemo {
public static void main(String args[])
{
// Creating a calendar object
Calendar calndr
= new GregorianCalendar(2018, 9, 2);
// Getting the maximum value that
// year field can have
int yr
= calndr.getActualMaximum(Calendar.YEAR);
System.out.println("The Maximum year: "
+ yr);
// Getting the maximum value that
// month field can have
int mon
= calndr.getActualMaximum(Calendar.MONTH);
System.out.println("The Maximum Month is: "
+ mon);
}
}
Output:
The Maximum year: 292278993
The Maximum Month is: 11
