Apples simulator - amended main method and toString() method

gistfile1.java

// prints out something like "Apple 27 (GRANNY_SMITH, 3)"
public String toString() {
    return String.format("Apple %d (%s, %s)",size,type,batchNumber);
}

public static void main(String[] args) {
        Random random = new Random(); // this is the line missing from the workshop pdf
        final int SIZE = random.nextInt(5) + 1;
        Apple[] apples = new Apple[SIZE]; // a randomly sized apples array
        for (int i = 0; i < SIZE; ++i) {
            AppleType[] types = AppleType.values();
            int whichType = random.nextInt(types.length);
            int size = random.nextInt(20) + 10;
            apples[i] = new Apple(size, types[whichType]); // create random apples
        }
        System.out.println("New apples: " + Arrays.deepToString(apples));
    }
