Java DateFormatSymbols setShortWeekdays()用法及代碼示例

Java中的DateFormatSymbols類的setShortWeekdays(String [] newShWeekds)方法用於將日曆工作日的短名稱(以字符串格式)設置為一些不同的字符串。例如，可以將“Sun”更改為“FRI”，將“Mon”更改為“WED”等。

用法:

public void setShortWeekdays(String[] newShWeekds)

參數：該方法采用一個參數newShWeekds，它是String類型的數組，表示將在現有工作日中替換的新字符串。

返回值：該方法以字符串格式返回修改後的工作日簡稱。

以下示例程序旨在說明setShortWeekdays()方法的使用。
示例1:

// Java code to demonstrate setShortWeekdays() 
  
import java.text.DateFormatSymbols; 
import java.util.Locale; 
  
public class DateFormat_Main { 
    public static void main(String args[]) 
    { 
        // Initialising DateFormatSymbols object 
        DateFormatSymbols format 
            = new DateFormatSymbols( 
                new Locale("en", "US")); 
  
        // Taking the default short weekdays 
        String[] shDays 
            = format.getShortWeekdays(); 
  
        // Displaying the original 
        System.out.print("Original: "); 
  
        for (int i = 1; i < shDays.length; i++) { 
            System.out.print(shDays[i] + "  "); 
        } 
        System.out.println(); 
  
        // Taking an alternative names 
        String[] modDays = { "WED", "THU", "FRI", 
                             "MON", "TUE", "SUN", "SAT" }; 
  
        // Setting the default into modified 
        format.setShortWeekdays(modDays); 
  
        // Displaying the mdified string 
        String[] modifiedDays 
            = format.getShortWeekdays(); 
  
        System.out.print("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.print(modifiedDays[i] + "  "); 
        } 
    } 
}

輸出：

Original: Sun  Mon  Tue  Wed  Thu  Fri  Sat  
Modified: WED  THU  FRI  MON  TUE  SUN  SAT

        for (int i = 1; i < shDays.length; i++) { 
            System.out.print(shDays[i] + "  "); 
        } 
        System.out.println(); 
  
        // Taking an alternative names with 
        // additional random strings 
        String[] modDays = { "WED", "THU", "FRI", 
                             "MON", "TUE", "SUN", 
                             "SAT", "ONE", "TWO" }; 
  
        // Setting the default into modified 
        format.setShortWeekdays(modDays); 
  
        // Displaying the mdified string 
        String[] modifiedDays 
            = format.getShortWeekdays(); 
  
        System.out.print("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.print(modifiedDays[i] + "  "); 
        } 
    } 
}

輸出：

Original: Sun  Mon  Tue  Wed  Thu  Fri  Sat  
Modified: WED  THU  FRI  MON  TUE  SUN  SAT  ONE  TWO
