## 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
```
