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: 2019The given calendar's month is: 1The 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: 2019The given calendar's month is: 9The given calendar's day is: 2
