Java Calendar getDisplayName()用法及代码示例

Calendar类的getDisplayName(int cal_field，int cal_style，Locale local)方法用于以给定样式(int cal_style)和locale(int local)返回日历字段(int cal_field)值的字符串表示形式。

用法:

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

参数：该方法具有三个参数：

cal_field：这是整数类型，是指要在其上执行操作的日历字段。
cal_style：这是整数类型，是指应该应用于字符串表示形式的样式。
local：这是Locale对象类型，是指表示字符串的语言环境。

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形式，如果没有可用的字符串表示形式，则返回null。

以下示例程序旨在说明Calendar类的getDisplayName()方法的用法：
示例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_TURKEY
Second object is : english_UK
Name of the first object: turkish (TURKEY)
Name of the second object: english (UK)

示例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); 
    }
