Java 根据贷款年限对应利率计算功能实现解析

public class MonthPay {
  public int total;//贷款总金额
  public int age; //贷款年限

  public void monthpay() {
    double monthpay;

    if (age<=3){
      monthpay = (6.03/100*total+total)/age;
    }else if(age <=5){
      monthpay = (6.12/100*total+total)/age;
    }else {
      monthpay = (6.39/100*total+total)/age;
    }
    System.out.println("***月供为"+monthpay/12);
  }
}

public class MonthPayTest {
  static Scanner sc = new Scanner(System.in);
  public static void main(String[] args) {
    MonthPay monthPay = new MonthPay();

    //选择贷款金额
    System.out.println("请输入贷款金额：");
    monthPay.total = sc.nextInt();
    System.out.println("请输入贷款年限：");
    monthPay.age = sc.nextInt();

    //计算月供
    monthPay.monthpay();
  }
}
