我有一个方法 compute(int months) 但它不会像我想要的那样迭代

Question

这是我的方法compute()，需要多少个月：

 public double compute(int months){
        double balance = employee.getSalary();
        double newBalance=0;
        double monthlyInterest = (bankName.getInterestRate())/12;
        double annualRaise = employee.getAnnualRaise();

if (months <=12){
      for (int i = 1; i <= months; i++){
        newBalance = (newBalance+balance)*(1+monthlyInterest);
      }
      return newBalance;
    }

    else{

      int cycle = months/12;

      while (cycle >0){
        for (int i = 1; i <= 12; i++){
          newBalance = (newBalance+balance)*(1+monthlyInterest);
        }
        cycle--;

        months = months - 12; //remainder of months

        balance = balance*(1+annualRaise/100); //new starting salary

      }

      for (int k = 1; k <= months; k++){
        newBalance = (newBalance+balance)*(1+monthlyInterest);
      }
      return newBalance;
    }

  }

为了给出一个上下文，

1. 余额：是员工在每个月初获得的固定月薪
2. monthly interest : 是每月根据员工银行余额计算的利率
3. 年加薪 : 是员工在新年伊始每月工资的加薪

我的输入示例如下：

Bill Jobs 54000.0 0 0.012 13

Bill Jobs 为员工，余额为 54K，年利率为 0%，银行年利率为 1.2%，计算时间为 13 个月以上。我想要的输出应该是：

Bill Jobs: salary is 54K, annual raise is 0% has balance of 706933.71 

当我调用计算方法时计算 706933.71 的余额，但我最终得到了

Bill Jobs: salary is 54K, annual raise is 0% has balance of 705852.63

13 个月后他的余额是 705852.63。

Answer 1

请参阅下面的基本计算方法，以计算每月加息 1.5% 的工资。您可以根据自己的要求进行修改。

import java.util.Scanner;

public class Salary {

public static void main(String[] args) {

    double salary = 24000;
    double interest = 1.5;
    double total = 0;
    Scanner sc = new Scanner(System.in);
    System.out.println("Enter the month = ");
    int month = sc.nextInt();
    if(month != 0 && month  < 13){
        for(int i=1; i <= month; i++){
            salary += total;
            total = (salary + (salary * (interest/100)))  ;
        }
        System.out.println("salary with interest "+total);
    }else{
        System.out.println("Enter the month from 1-12");
    }


   }

}
