How to use this method?

Question

I am very close to finishing my task, but I can't figure out how to call findChange() correctly. My guess is that it needs to be in the main method. But when findChange(); call it, it asks for int, List<Integer>, List<Integer> so how do I do this "correctly" so to speak.

CODE

import java.io.*;
import java.util.*;
import java.lang.*;

public class homework5 {

    public static int change;

    public static void main(String[] args)
        throws FileNotFoundException 
    { //begin main

        ArrayList<Integer> coinTypes = new ArrayList<Integer>();//array to store
        //coin types

        Integer i;
        File f = new File (args[0]);
        Scanner input = new Scanner(f); //initialize scanner
        input.nextLine();
        while(input.hasNextInt()) {
            i = input.nextInt();
            coinTypes.add(i);
        }
        change = coinTypes.get(coinTypes.size()-1); //this will add all ints
        coinTypes.remove(coinTypes.size()-1);
        System.out.println("Found change"); //used for debugging
        System.out.println("Change: " + change);

        //findChange(); ideal spot to call the method
        //System.out.println(coinTypes);
    }

    boolean findChange(int change, List<Integer> coinTypes,
                       List<Integer> answerCoins) 
    { //contains means of
        //finding the change solutions
        if(change == 0) {
            return true; //a solution
        }
        if(change < 0) {
            return false; //if negative it can't be a solution
        } else {
            for(Integer coin : coinTypes) {
                if(findChange(change - coin, coinTypes, answerCoins)){
                    answerCoins.add(coin); //if it works out add it to the
                    return true;         //solution List
                }
            }

        }

        List<Integer> answer = new ArrayList<Integer>();
        boolean canFindChange = findChange(change, coinTypes, answer);
        if(canFindChange) { //if there is a solution, print it
            System.out.println(answer);
        } else { System.out.println("No change found");
        }
        return false; //else return false
    }

}

This program calculates all the different ways to show change for a certain amount of money ie: 143 ($1.43). All I gotta do is call findChange() to main and it should work, what am I missing?

EDIT I just realized I didn't specify the method call I need help with I apologize for any unclearness

INPUT FILE

// Coins available in the USA, given in cents.  Change for $0.09?
1 5
9

CURRENT OUTPUT

Change: 9

WANT

Change: 9
['solutions to all possible combinations to make $0.09']
