求不同利率下的贷款（利率从5%到8%，每次递增1/8）

import java.util.Scanner;
public class Dooo {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
System.out.println("enter loan amount");//输入贷款总额
double loan=input.nextDouble();
System.out.println("choose number of years");//输入贷款年限

    int year=input.nextInt();

    double intersetRate=0.05;//年利率

System.out.printf("%-20s%-20s%-20s\n","Interest Rate","Monthil Payment","Total Payment");

while (intersetRate<0.081){
    System.out.printf("%-4.3f%%                   ",intersetRate*100);

    double monthlyPayment=loan*(intersetRate/12)/(1-(1/Math.pow((1+intersetRate/12),year*12)));//年利率/12为月利率，数学公式求月支付额度

    System.out.printf("%-20.2f",monthlyPayment);//输出每月支付额度

    double totalPayment=monthlyPayment*year*12;

    System.out.printf("%-20.2f\n",totalPayment);//输出总支付额

    intersetRate+=0.00125;//利率增长1/8；从5%到8%
}

        }
    }
