import java.text.DecimalFormat;
import java.util.Currency;
import java.util.Locale;

public class Main {
    public static void main(String[] args)
    {

        // Get the Currency Instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Stores the values
        String values = deciFormat.getCurrency()
                            .getDisplayName();

        // Prints the currency
        System.out.println(values);
    }
}

Output:

    public static void main(String[] args)
    {

        // Get the Currency Instance

        String values = deciFormat.getCurrency()
                            .getDisplayName();
