Question

Write a program in java to compute the monthly payment for investment for different interest rate. One for 5 years and another for 10 years, the initial rate is 3.75% with an increment of 0.025%

P= r*(pv)/1-(1+r)^-n

P= payment

R= interest rate

Pv =Investment

Answer 1

import java.util.Scanner;
public class investment{
 
 public static void main(String[] args) {
    Scanner in1 = new Scanner(System.in); 
    System.out.print("Payment amount: "); 
    double pmt = in1.nextDouble();
    System.out.print("Investment amount: ");
        double investmnt = in1.nextDouble();
        System.out.print("Rate of interest: ");
        double rate1 = in1.nextDouble();
        System.out.print("Number of years: ");
        int year1 = in1.nextInt();
        
        rate1 *= 3.75;
        
        System.out.println("Years    monthlyValue");
        for(int j = 1; j <= year; j++) {
        int formatter1 = 5;
            if (j >= 5) formatter1 = 10;
                System.out.printf(i + "%"+formatter1+".2f\n", monthlyValue(investmnt, rate1/12, j));
       }
         }
 
 public static double monthlyValue(double P, double monthlyrateofinterest, int years) {
                return P= monthlyrateofinterest*(pmt*investmnt)/1-(1+monthlyrateofinterest)pow(-n), years * 12);
        }
}
