如何控制 DateFormat 返回的月份和日期名称的大小写?

Here is a quick test program:

    public static void main( String[] args )
{
    Date date = Calendar.getInstance().getTime();

    System.out.println("Months:");
    printDate( "MMMM", "en", date );
    printDate( "MMMM", "es", date );
    printDate( "MMMM", "fr", date );
    printDate( "MMMM", "de", date );

    System.out.println("Days:");
    printDate( "EEEE", "en", date );
    printDate( "EEEE", "es", date );
    printDate( "EEEE", "fr", date );
    printDate( "EEEE", "de", date );

}

public static void printDate( String format, String locale, Date date )
{
    System.out.println( locale + ": " + (new SimpleDateFormat( format, new Locale( locale ) )).format( date ) );
}

输出是:

<代码>月份:zh: 九月es: 九月法国:九月去:九月天:zh: 星期一es: 月牙fr: 隆迪de: 蒙塔格

如何控制名称的大小写.出于某种原因，西班牙语和法语似乎总是返回以小写字母开头的名称.
