Java中的 DateFormatSymbols setShortMonths() 方法及示例

Java中DateFormatSymbols 类的setShortMonths(String[] newShMonth )方法用于将字符串格式的日历月份的短名称设置为不同的字符串。例如，“Jan”可以更改为“FEB”，“JUN”可以更改为“GEEK”等。

句法：

public void setShortMonths(String[] newShMonth)

参数：该方法采用一个参数newShMonth ，它是一个String类型的数组，引用了现有Months中要替换的新字符串。

返回值：该方法以字符串格式返回修改后的月份名称。

下面的程序说明了 setShortMonths() 方法的使用。
示例 1：

// Java code to demonstrate setShortMonths()
  
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.getShortMonths();
  
        // Displaying the original
        System.out.println("Original: ");
  
        for (int i = 0; i < Days.length; i++) {
            System.out.println(Days[i] + "  ");
        }
  
        // Taking an alternative names with
        // additional random strings
        String[] modDays = { "GEEK", "FOR",
                             "GEEK", "DEC",
                             "NOV", "JAN",
                             "FEB" };
  
        // Setting the default into modified
        format.setShortMonths(modDays);
  
        // Displaying the modified string
        String[] modifiedDays
            = format.getShortMonths();
  
        System.out.println("Modified: ");
        for (int i = 0; i < modifiedDays.length; i++) {
            System.out.println(modifiedDays[i] + "  ");
        }
    }
}
