    text
    copied!<p>I've been asked to create a method that returns all of the factors as an array list. Any help would be appreciated as I've been stuck for some while now.</p> <pre><code>/** * Determines whether the number has factors. * * @return true iff the number has a factor */ public boolean hasMoreFactors() { if (number &gt;= 2) { return true; } else { return false; } // return (number &gt;= 2); } /** * Is number divisible by a given other number? * * @param otherNumber the number we test whether it divides the object's number * @return true iff the number is divisible by otherNumber */ public boolean isDivisible(int otherNumber) { if (number % otherNumber == 0) { return true; } else { return false; } } /** * Determine next factor. * pre-condition: call only if hasMoreFactors * returns true * * @return a factor of the object's number */ public int nextFactor() { int triedFactor = 2; while (! isDivisible(triedFactor)) { triedFactor = triedFactor+1; } number = number / triedFactor; return triedFactor; } /** * Print all factors of the generator's number on standard output. */ public void printAllFactors() { System.out.println("Factors of " + number); while (hasMoreFactors()) { System.out.println(nextFactor()); } System.out.println("That's it."); } /** * Main method: Read an integer and print all its factors. */ public static void main(String[] args) { System.out.print("Please enter a number greater or equal 2: "); Scanner sc = new Scanner(System.in); int num = sc.nextInt(); System.out.println(); FactorGenerator gen = new FactorGenerator(num); gen.printAllFactors(); } </code></pre> <p>}</p>
