Answer 1

The answer to the student's question about the NumberFormat class is c) both percentage formats and locale-specific currency. NumberFormat provides numeric formatting catering to locale differences in displaying numbers, including currency symbols and percentage presentations.

Step-by-step explanation:

The student's question is asking which numeric formatting capabilities the NumberFormat class of the package provides. The correct answer is option c) both percentage formats and locale-specific currency. The NumberFormat class in many programming language's standard libraries, such as Java's java.text package, is indeed designed to handle both the formatting of numbers as percentages and the formatting of currency values in a way that adheres to the rules of a specific locale. This localization ensures that numeric values are displayed in a format that is familiar and easily readable by users from different regions, respecting differences such as decimal separators, grouping separators, and currency symbols.

For instance, formatting a number as a currency will yield "$1,000.00" in the US locale, while in the German locale it would be represented as "1.000,00 €". And for percentages, 0.85 might be formatted as "85%" in the US locale, whereas in France, it could appear as "85 %" with a space. Thus, the NumberFormat class provides a crucial tool in internationalizing software applications to accommodate various regional standards.
