import java.util.Scanner;
public class Question {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter loan amount:");
double loanAmount = input.nextDouble();
System.out.print("Enter number of years: ");
int numberOfYears = input.nextInt();
double annualInterestRate = 5.0;
System.out.printf("%-18s%-18s%-18s\n", "Interest Rate",
"Monthly Payment", "Total Payment");
while (annualInterestRate <= 8.0) {
double monthlyInterestRate = annualInterestRate / 1200;
double monthlyPayment = loanAmount
* monthlyInterestRate
/ (1 - 1 / Math.pow(1 + monthlyInterestRate,
numberOfYears * 12));
double totalPayment = monthlyPayment * numberOfYears * 12;
System.out.printf("%-18.3f%-18.2f%-18.2f\n", annualInterestRate,
monthlyPayment, totalPayment);
annualInterestRate = annualInterestRate + 1.0 / 8;
}
}
