Currency

TheCurrencyclass encapsulates information about a currency. It defines no constructors. The

methods supported byCurrencyare shown in Table 18-10. The following program

demonstratesCurrency:

// Demonstrate Currency.

import java.util.*;

class CurDemo {

public static void main(String args[]) {

Currency c;

c = Currency.getInstance(Locale.US);

System.out.println("Symbol: " + c.getSymbol());

System.out.println("Default fractional digits: " +

c.getDefaultFractionDigits());

}

}

The output is shown here:
