这就是我正在与之合作。这是一个月付款贷款计算器。我不断收到一个错误“方法monthlyPayment(double,int,int)对于类型Assignment 8是未定义的。”这个错误显示在主要方法中。该错误是在第27行如何为未定义的方法解决此错误?
CLASS
public class LoanCalc {
public static double monthlyPayment(double amountBorrowed, int loanLength, int intRate) {
double principal;
double interestRate;
double monthlyPayment;
principal = amountBorrowed;
interestRate = intRate/100/12;
monthlyPayment = (interestRate * principal)/
(1- Math.pow((1 + interestRate) , - loanLength * 12));
return monthlyPayment;
}
}
主要方法

10 double amountBorrowed = kbd.nextDouble();
11
12 System.out.println("Enter the interest rate: ");
13 int intRate = kbd.nextInt();
14
15 System.out.println("Enter the minimum length of loan: ");
16 int minLength = kbd.nextInt();
17
18 System.out.println("Enter the maximum length of loan: ");
19 int loanLength = kbd.nextInt();
20 while (loanLength < minLength) {
21 System.out.println("Invalid input: Input must be greater than 22 minimum length of loan");
23 System.out.println("Enter the maximum length of loan: ");
24 loanLength = kbd.nextInt();
25 }
26
27 double payment = monthlyPayment(amountBorrowed, loanLength, intRate);
28 System.out.println(payment);
29
30 }
}
