MITS4002 Activity 03
Analysis:
In the given problem, we need to design a program which would take amount of investment, rate
of annual interest & no. of years as input from the user and calculates the future investment value
based on the formula provided. The output of the program will be the calculated future
investment value.
Design:
1. All the variables were declared with their datatypes.
2. Main class was declared and inputs were taken from the user with scanner class object.
3. The future investment value was calculated based on the inputs from the user with the
formula given to us in the problem statement.
4. The program printed the calculated “fi” value.
5. The program was made such that it could handle exceptions.
Coding:
import java.util.Scanner;
import java.util.InputMismatchException;
public class fiValue {
public static void main (String[] args) {
try {
double fi=0.0;
Scanner scanner= new Scanner (System.in);
System.out.println("Amount of investment required: ");
double amt= scanner.nextDouble();
System.out.println("Rate of interest required (in %): ");
double interest= scanner.nextDouble();
System.out.println("Number of years required: ");
double years=scanner.nextDouble();
fi= amt* Math.pow((1+interest/100),years);
System.out.println("Accumulated value is: " + fi);
}
catch (InputMismatchException e) {
System.out.println("You must enter valid numericals");
main(null);
}
catch (Exception e) {
System.out.println(e);
main(null);
}

Testing:
1. The sample values were entered as input and the program returned the correct value as
output.
2. Another set of sample values were entered and the correct answer was shown.
