Java, computing the following formula

I am trying the write the formula in the image using Java. However, I get the wrong output. This is what I am so far for the computation.
Assume Input is: Loan Amount = 50000 and Length = 3 year.My output is currently "676.08" for ‘Monthly Payment’ and "25661.0" for "Total Interest Payment" ‘Monthly payment’ should be "1764.03" and ‘Total Interest Payment’ should be "13505.05" Code is: “//Program that displays the interest rate and monthly payment based on the loan amount and length of loan the user inputs.

import java.util.Scanner;

public class bankLoanSelection{

public static void main(String[] args){
    
    Scanner input = new Scanner(System.in);

    //Declarations.

    double interestRate;
    final double n = 12;
    
    //Generates an account number in the range of 1 to 1000.

    int accountnumber = (int)(Math.random() * 1000)+1;

    //User input
    
    System.out.print("Enter Loan Amount: $");
    double L = input.nextDouble();
    System.out.print("Length of Loan (years): ");
    double i = input.nextDouble();

    //selection structure using if and if-else statements.

    if (L <= 1000)
    interestRate = .0825;
    else if (L <= 5000)
    interestRate = .0935;
    else if (L <= 10000)
    interestRate = .1045;
    else interestRate = .1625;
    
    
    //Computations. 

    double MonthlyPayment = L * (interestRate / n) * Math.pow(1 + interestRate / n, i * n) / Math.pow(1 + interestRate / n, i * n) - 1;
    double TotalAmountOfLoan = MonthlyPayment * i * n;
    double TotalInterest = L - TotalAmountOfLoan;

    //Output.

    System.out.println("Account Number: #" + accountnumber);
    System.out.println("Loan Amount: $" + L);
    System.out.println("Loan Length (years): " + i);
    System.out.println("Interest Rate: " + interestRate * 100 + "%");
    System.out.printf("Total Monthly Payment: $%.2f%n", MonthlyPayment); //Rounds second decimal
    System.out.println("Total Interest Payments: $" + TotalInterest);
    
}

}“ Formula

>Solution :

You can not put round parentheses between condition.

It should be:

double MonthlyPayment = L * ((interestRate / n) * Math.pow(1 + interestRate / n, i * n)) 
                           / (Math.pow(1 + interestRate / n, i * n) - 1);
