mport java.util.Scanner;
public class ComputeLoan {
    public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        System.out.println("Enter annual interest rate, e.g., 7.25%: ");
        double annualInterestRate = input.nextDouble();

        double monthlyInterestRate = annualInterestRate / 1200;

        System.out.println("Enter number of years as an integer, e.g, 5: ");
        int numberOfYears = input.nextInt();

        System.out.println("Enter loan amount, e.g., 120000.95: ");
        double loanAmount = input.nextDouble();

        double monthlyPatment = loanAmount * monthlyInterestRate / (1-
                1 / Math.pow(1 + monthlyInterestRate, numberOfYears * 12));
        double totalPayment = monthlyPatment * numberOfYears * 12;

        System.out.println("The monthly payment is $" + (int)(monthlyPatment * 100) / 100.0);
        System.out.println("The total payment is $" + (int)(totalPayment * 100 ) / 100.0);
    }
}

Math类是在java.lang包中，而java.lang包中的所有类是隐式被导入的，因此，不需要显式导入Math类。
