Java Calendar getDisplayName()用法及代碼示例

Calendar類的getDisplayName(int cal_field，int cal_style，Locale local)方法用於以給定樣式(int cal_style)和locale(int local)返回日曆字段(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)

參數：該方法具有三個參數：

cal_field：這是整數類型，是指要在其上執行操作的日曆字段。
cal_style：這是整數類型，是指應該應用於字符串表示形式的樣式。
local：這是Locale對象類型，是指表示字符串的語言環境。

返回值：該方法以傳遞樣式的形式返回給定字段的字符串表示形式，如果沒有可用的字符串表示形式，則返回null。

以下示例程序旨在說明Calendar類的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); 
    } 
}

輸出：

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); 
    } 
}
