语法:

public void setWeekdays(String[] *newWeekds*)

参数:该方法取一个参数 newWeekds ，该参数是 字符串 类型的数组，指的是在现有工作日中要替换的新字符串。 返回值:该方法以字符串形式返回工作日的修改名称。 下面的程序说明了 setWeekdays()方法的使用。 例 1:****

Java 语言(一种计算机语言，尤用于创建网站)

// 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] + "  ");
        }
    }
}
