參數：該方法采用一個參數newWeekds，該參數是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工作日的已修改名稱。

以下示例程序旨在說明setWeekdays()方法的使用。
示例1:

// Java code to demonstrate setWeekdays() 
  
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[] Days = format.getWeekdays(); 
  
        // Displaying the original 
        System.out.print("Original: "); 
        for (int i = 1; i < Days.length; i++) { 
            System.out.print(Days[i] + "  "); 
        } 
        System.out.println(); 
  
        // Taking an alternative names with 
        // additional random strings 
        String[] modDays = { "WEDNESDAY", "THURSDAY", 
                             "FRIDAY", "MONDAY", 
                             "TUESDAY", "SUNDAY", 
                             "SATURDAY" }; 
  
        // Setting the default into modified 
        format.setWeekdays(modDays); 
  
        // Displaying the modified string 
        String[] modifiedDays = format.getWeekdays(); 
  
        System.out.print("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.print(modifiedDays[i] + "  "); 
        } 
    } 
}

輸出：

Original: Sunday  Monday  Tuesday  Wednesday  Thursday  Friday  Saturday  
Modified: WEDNESDAY  THURSDAY  FRIDAY  MONDAY  TUESDAY  SUNDAY  SATURDAY

示例2:

// 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[] Days = format.getWeekdays(); 
  
        // Displaying the original 
        System.out.print("Original: "); 
        for (int i = 1; i < Days.length; i++) { 
            System.out.print(Days[i] + "  "); 
        } 
        System.out.println(); 
  
        // Taking an alternative names with 
        // additional random strings 
        String[] modDays = { "WEEK", "RANDOM", 
                             "WEDNESDAY", "THURSDAY", 
                             "FRIDAY", "MONDAY", 
                             "TUESDAY", "SUNDAY", 
                             "SATURDAY" }; 
  
        // Setting the default into modified 
        format.setWeekdays(modDays); 
  
        // Displaying the mdified string 
        String[] modifiedDays = format.getWeekdays(); 
  
        System.out.print("Modified: "); 
        for (int i = 0; i < modifiedDays.length; i++) { 
            System.out.print(modifiedDays[i] + "  "); 
        } 
    } 
}

輸出：

Original: Sunday  Monday  Tuesday  Wednesday  Thursday  Friday  Saturday  
Modified: WEEK  RANDOM  WEDNESDAY  THURSDAY  FRIDAY  MONDAY  TUESDAY  SUNDAY  SATURDAY
