日付の区切り記号のプレース ホルダーを使用する代わりに、正確な文字列を 1 年の月のパターンでは、日付の区切り記号を設定することをお勧めします。We recommend that you set the date separator in the year month pattern to an exact string instead of using the date separator placeholder. たとえば、年日パターンを取得するには、"yyyy MM"する年の月のパターンを設定します。For example, to get the pattern MM-yyyy, set the year month pattern to "MM-yyyy".
