# Java: Compute the future investment value at a given interest rate for a specified number of years

## Java Method: Exercise-8 with Solution

Write a Java method to compute the future investment value at a given interest rate for a specified number of years.

Sample data (Monthly compounded):

Input the investment amount: 1000

Input the rate of interest: 10

Input number of years: 5

**Sample Solution:**

**Java Code:**

```
import java.util.Scanner;
public class Exercise8 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Input the investment amount: ");
double investment = in.nextDouble();
System.out.print("Input the rate of interest: ");
double rate = in.nextDouble();
System.out.print("Input number of years: ");
int year = in.nextInt();
rate *= 0.01;
System.out.println("Years FutureValue");
for(int i = 1; i <= year; i++) {
int formatter = 19;
if (i >= 10) formatter = 18;
System.out.printf(i + "%"+formatter+".2f\n", futureInvestmentValue(investment, rate/12, i));
}
}
public static double futureInvestmentValue(double investmentAmount, double monthlyInterestRate, int years) {
return investmentAmount * Math.pow(1 + monthlyInterestRate, years * 12);
}
}
```

Sample Output:

Input the investment amount: 1000 Input the rate of interest: 10 Input number of years: 5 Years FutureValue 1 1104.71 2 1220.39 3 1348.18 4 1489.35 5 1645.31
