Java 日历 getDisplayName()方法及示例

Calendar类的 getDisplayName(int cal_field , int cal_style , Locale local ) 方法用于返回一个日历字段(int cal_field)在给定风格(int cal_style)和locale(int local)中的字符串表示。

语法

public String getDisplayName(int cal_field, int cal_style, Locale local)

参数： 该方法需要三个参数。

返回值： 该方法以传递样式的形式返回给定字段的字符串表示，如果没有可用的字符串表示，则返回空。

下面的程序说明了日历类的getDisplayName()方法的工作原理：

例1 :

// Java Code to illustrate// getDisplayName() Method  import java.util.*;  public class Calendar_Demo_Locale {    public static void main(String args[])    {          // Creating Locale objects class        Locale first_obj = new Locale("TURKISH", "Turkey");          Locale sec_obj = new Locale("ENGLISH", "UK");          // Displaying the objects        System.out.println("First"                           + " object is : " + first_obj);        System.out.println("Second"                           + " object is : " + sec_obj);          // Getting the display names        String obj_nm = first_obj.getDisplayName();          // Displaying the results        System.out.println("Name of the"                           + " first object: " + obj_nm);          // Getting the display names        obj_nm = sec_obj.getDisplayName();        System.out.println("Name of the"                           + " second object: " + obj_nm);    }}

输出:

First object is : turkish_TURKEYSecond object is : english_UKName of the first object: turkish (TURKEY)Name of the second object: english (UK)

例2 :

// Java Code to illustrate// getDisplayName() Method  import java.util.*;  public class Calendar_Demo_Locale {    public static void main(String args[])    {          // Creating Locale objects class        Locale first_obj = new Locale("RUSSIAN", "Russia");          Locale sec_obj = new Locale("GERMAN", "Germany");          // Displaying the objects        System.out.println("First"                           + " object is : " + first_obj);        System.out.println("Second"                           + " object is : " + sec_obj);          // Getting the display names        String obj_nm = first_obj.getDisplayName();          // Displaying the results        System.out.println("Name of the"                           + " first object: " + obj_nm);          // Getting the display names        obj_nm = sec_obj.getDisplayName();        System.out.println("Name of the"                           + " second object: " + obj_nm);    }}

输出:

First object is : russian_RUSSIASecond object is : german_GERMANYName of the first object: russian (RUSSIA)Name of the second object: german (GERMANY)
