Java 日历 get()方法及实例

Calendar类的 get(int field_value ) 方法用于返回参数中给定的日历字段的值。

语法

public int get(int field)

参数： 该方法需要一个整数类型的参数 field_value ，指的是需要返回其值的日历。

返回值： 该方法返回所传递字段的值。

下面的程序说明了日历类的get()方法的工作原理：

示例1 :

// Java Code to illustrate
// get() Method
  
import java.util.*;
  
public class CalendarClassDemo
    extends GregorianCalendar {
    public static void main(String args[])
    {
        // Creating a calendar
        Calendar calndr = Calendar.getInstance();
  
        // Getting the value of all
        // the calendar date fields
        System.out.println("The given calendar's"
                           + " year is: " + calndr.get(Calendar.YEAR));
        System.out.println("The given calendar's"
                           + " month is: " + calndr.get(Calendar.MONTH));
        System.out.println("The given calendar's"
                           + " day is: " + calndr.get(Calendar.DATE));
    }
}

输出:

The given calendar's year is: 2019
The given calendar's month is: 1
The given calendar's day is: 13

例2 :

// Java Code to illustrate
// get() Method
  
import java.util.*;
  
public class CalendarClassDemo
    extends GregorianCalendar {
    public static void main(String args[])
    {
        // Creating a calendar object
        Calendar calndr = new GregorianCalendar(2018, 9, 2);
  
        // Getting the value of all
        // the calendar date fields
        System.out.println("The given calendar's"
                           + " year is: " + calndr.get(Calendar.YEAR));
        System.out.println("The given calendar's"
                           + " month is: " + calndr.get(Calendar.MONTH));
        System.out.println("The given calendar's"
                           + " day is: " + calndr.get(Calendar.DATE));
    }
}

输出:

The given calendar's year is: 2019
The given calendar's month is: 9
The given calendar's day is: 2
