CurrencyConversion 为用户提供将美元转换为英镑或其他方式的选择。（你可以假设 1 美元 = 1.64 英镑。）

// Import scanner 
import java.util.Scanner;

public class MoneyConversion {

    public static void main (String[] args) {

        // Declare variable
        final double RATE  = 1.64;

        // Declare currency 
        double dollar;
        double Pounds;

        // Call scanner from keyBoard
        Scanner fromKeyboard = new Scanner(System.in);

        // Ask user to enter the amount of pounds 
        System.out.print("Please write number of pounds");

        // Read the value into variable 
        Pounds = fromKeyboard.nextDouble();

        // Write the method for currency conversion
        dollar = Pounds * RATE;

        System.out.println("The number of dollars is "  +  dollar);

    } // End of main


} // End currency conversion

为不同的货币换算制作不同的类如下：

public static void main(String[] args) {
        Scanner fromKeyboard = new Scanner(System.in);
        System.out.print("Please write number of pounds");
        System.out.println("The number of dollar is "  +  convertToDollar(fromKeyboard.nextDouble()));
    }    

public static double convertToDollar(double pound){
        double rate  = 1.64;
        double Pounds;
        return( pound * rate);
    }
