Java 如何获得正确的输出？

所以对于这一点，我似乎只得到了输出的美元数量的“无穷大”。我想这和数学有关。（不要介意那些草率的代码，我被告知要在不做太多修改的情况下对其进行调试）这是我似乎遇到的唯一问题。除此之外，其他一切都很好

        months = reader.nextInt();
        System.out.print("What is the decimal interest rate? ");
        annualInterest = reader.nextDouble();

        //Output
        calculatePayment(price, downPayment, tradeIn, (int) annualInterest, months);
    }

    public static void calculatePayment(int price, int downPayment, int tradeIn,
            int months, double annualInterest) {

        int loanAmt;
        double payment;

        //Calculations
        interest = (double) annualInterest/ (double) 12 ;
        loanAmt = (int) (price - downPayment - tradeIn);
        payment = loanAmt / ((1.0 / interest) - (1.0 / (interest * Math.pow(1.0, annualInterest))));
        String custName = "Any Name";

        System.out.print("The monthly payment for ");
        System.out.print(custName + " is $ ");
        System.out.println((double) payment);

        return;
    }
}

calculatePayment的参数不匹配
计算付款（价格、首付款、折价，（国际）年利息、月）；应
计算付款（价格、首期付款、折价，月，年利息）
你的数学很差。
math.pow（1.0，annualInterest）总是
所以你有1/利息-1/利息，它是0。然后你有loanAmt/0.0==>无穷大
回去检查你的付款计算

@MadProgrammer实际上他没有。下一个电话将跳过换行符。告诉我@panzo，你为什么要将利率（转换为

int

，因此小数部分被截断）作为月数，将月数作为利率？@immibis你知道，我真的很讨厌

扫描器

@immibis哪一行？很抱歉，我对编码还不熟悉。@panzo cliff2310说它已经改变了这一点，但它仍然可以无限运行，这是数学问题还是代码本身的问题。
