MITS4002 Activity 03
Analysis
In this program, future investment value will be calculated using the formula which is being
provided. For the program, input will take in the form of double data types and pow function
is being used which is in java.util.Math library. The value which is being taken from the user
is the amount of investment, monthly interest rate and a number of years as a double data
type. The output which is being displayed will be the future investment value which will be
provided to the customer after investing money for number years at after a monthly interest
rate.
Design
The following criteria were designed before coding of a program:
 The flow of execution of the program is top to down.
 Data types are being defined for every variable which are being used
 Double data types will be used for every variable to maintain the compatibility of the
program.
 Scanner class will be used for taking the input of variable which is being asked by the user.
 Power function will be used for calculating the power of monthly interest rate and the number
of years.
 Future investment value is being calculated after performing the following operations
according to the formula which is being provided.
Code
import java.util.Scanner;
import java.lang.Math;
public class Main
{
public static void main(String[] args) {
System.out.println("Enter Investment Amount: ");
Scanner sc = new Scanner(System.in);
double amount_of_investment = sc.nextDouble();

System.out.println("Enter annual interest rate:");
double interest_rate = sc.nextDouble();
System.out.println("Number of years: ");
double number_of_years = sc.nextDouble();
double future_value_of_investment;
number_of_years = number_of_years *12;
interest_rate = (1+ interest_rate/100);
interest_rate = Math.pow(interest_rate, number_of_years);
future_value_of_investment = amount_of_investment *
interest_rate;
System.out.println("Accumulated values is "+
future_value_of_investment);
}
}

Testing:
 Program will be exited if any wrong value is being inserted by showing wrong input.
 Other criteria and examples were also calculated according to the formula which is
being used in this program.
