Question

我正在尝试创建一个收取货币金额$ XX.xx的java程序，并输出更改的数量e-g季度，角钱，镍币等数量。

我无法将扫描程序从公共类传递给转换中使用的方法，然后在main方法中调用所述方法。

到目前为止，这是我的代码。

import java.util.Scanner;

public class moneyConverter{


double currentAmount = (int)(money *100.00);                            //variables

public static Scanner scan = new Scanner(System.in);

public static double money = scan.nextDouble();


    public static void main(String[] args)
    {

        double money = 0.0;

        money.Dollar();
        money.Quarter();
         money.Dime();                                                  
        money.Nickel();
        money.Penny();


    }

    public static void Dollar(Scanner scan){                            

        double dollarAmount = scan.nextDouble() / 100.00;
        double currentAmount = dollarAmount % 100.00;

        System.out.println("Dollars: " +dollarAmount);

        return;

    }

    public static void Quarter(Scanner scan){

        double dollarAmount = scan.nextDouble() / 25.00;
        double currentAmount = dollarAmount % 25.00;

        System.out.println("Quarters: " +dollarAmount);

        return;

    }

    public static void Dime(Scanner scan){

        double dollarAmount = scan.nextDouble() / 10.00;
        double currentAmount = dollarAmount % 10.00;

        System.out.println("Dimes: " +dollarAmount);

        return;

    }

    public static void Nickel(Scanner scan){

        double dollarAmount = scan.nextDouble() / 5.00;
        double currentAmount = dollarAmount % 5.00;

        System.out.println("Nickels: " +dollarAmount);

        return;

    }

    public static void Penny(Scanner scan){

        double currentAmount = currentAmount;

        System.out.println("Pennies: " +currentAmount); 

        return;

    }
}

有人可以帮忙吗？

Answer 1

attribute_id是money，它没有您尝试调用的方法。

通过执行以下操作来调用double类中的方法：

moneyConverter

Java - 将扫描器传递给方法然后调用方法
