比较不同利率下的贷款

import java.util.Scanner;
class Main {
  public static void main(String[] args) {
    //Create a Scanner
    Scanner input = new Scanner(System.in);
    
    //Enter loan amount
    System.out.print("请输入贷款总额，比如 300000：");
    double loanAmount = input.nextDouble(); 
    
    //Enter number of years
    System.out.print("请输入年数，比如 5：");
    int numberOfYears = input.nextInt();
       
    double annualInterestRate = 5.0;

    for(int i = 0; i <= 24;i++){
      //Obtain monthly interest rate
      double monthlyInterestRate = annualInterestRate / 1200;

      //Calculate payment
      double monthlyPayment = loanAmount * monthlyInterestRate / 
      (1 - 1/Math.pow(1 + monthlyInterestRate,numberOfYears * 12));
      double totalPayment = monthlyPayment * numberOfYears * 12;
      
      //Display results
      if(i == 0)
        System.out.print("Interest Rate       Monthly Payment     Total Payment\n");
      
      System.out.print(annualInterestRate + "%\t\t\t\t");
      System.out.printf("%-20.2f%-10.2f\n", monthlyPayment, totalPayment);
      
      annualInterestRate += 0.125;
     }
    input.close();
