SCJP題庫第164題
Given:
1. d is a valid, non-null Date object
2. df is a valid, non-null DateFormat object set to the current locale
What outputs the current locale's country name and the appropriate version of d's date?
A. Locale loc = Locale.getLocale();
System.out.println(loc.getDisplayCountry()
+ " " + df.format(d));
B. Locale loc = Locale.getDefault();
System.out.println(loc.getDisplayCountry()
+ " " + df.format(d));
C. Locale loc = Locale.getLocale();
System.out.println(loc.getDisplayCountry()
+ " " + df.setDateFormat(d));
D. Locale loc = Locale.getDefault();
System.out.println(loc.getDisplayCountry()
+ " " + df.setDateFormat(d));
Ans: B
解說:
Locale是本地化(/國際化)程式撰寫工具方法，locale 是指一個有共同語言和習慣的地理或政治區域。在 Java 編程語言中，locale 由 Locale 對像來代表。對 locale 敏感的操作（例如排序原則和日期格式化）將根據 Locale 而變化。
