Question
Consider the application of international e-commerce. Now you are asked to extend that solution to deal with another aspect of doing business internationally online: depending on the location of the consumers, the system is supposed to automatically convert the price into the local currency and display it. Provide a skeleton implementation in Java. The code should be pretty close to compilable with correct Java syntax; however, it does not actually have to be ran through a Java IDK. The specifics with actual operations can be sketchy. The main emphasis is on the structure and how well the code works together (calling other methods).
Explanation / Answer
import java.text.NumberFormat;
import java.util.Currency;
import java.util.Locale;
public class NumberToCurrencyExamples
{
public static void main(String[] args)
{
//This is the amount which we want to format
Double currencyAmount = new Double(123456789.555);
//Get current locale information
Locale currentLocale = Locale.getDefault();
//Get currency instance from locale; This will have all currency related information
Currency currentCurrency = Currency.getInstance(currentLocale);
//Currency Formatter specific to locale
NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance(currentLocale);
//Test the output
System.out.println(currentLocale.getDisplayName());
System.out.println(currentCurrency.getDisplayName());
System.out.println(currencyFormatter.format(currencyAmount));
}
}
