Thread: Need help will inflation calculator

Hello, I need at create an inflation calculator that should execute as follows:

Enter the current cost of the item: 1000

Enter the expected inflation rate per year
(Enter as a percentage and do not include the percent sign): 6

Enter the whole number of years in the future to project cost: 10

At 6.00% inflation per year, the cost in 10 year(s) will be $1,790.85.

Process completed.

So far my code looks like this:

InflationCalculator.java:

import java.util.Scanner;

class InflationCalculator {
public static void main(String[] args){
Scanner keyboard = new Scanner (System.in);
RateOfInflation rateObject = new RateOfInflation();

int cost, numberOfYears;
double rateOfInflation;

System.out.print("Enter the current cost of the item:");
cost = keyboard.nextInt();

System.out.println("Enter the expected inflation rate per year");
System.out.print("(Enter as a percentage and do not include the percent sign");
rateOfInflation = (keyboard.nextInt() * .01);

System.out.print("Enter the whole number of years in the future to project cost:");
numberOfYears = keyboard.nextInt();

rateObject.calcMethod(cost, numberOfYears, rateOfInflation);


}
}

and
RateOfInflation.java

public class RateOfInflation {
public double calcMethod(int cost, int numberOfYears, double rateOfInflation){
int n = 0;
double answer;
while (n == numberOfYears){
answer = (cost * rateOfInflation) + cost;
n++;
System.out.println( answer );
}

}
}

Not even sure if I have the right approach at this, been reading java for the past couple weeks and its driving me crazy. Thanks for any help that can be provided.

Are you doing the OPs homework for him?

Everything looks good to me, except I would look at your method thats actually calculating the inflation.
