Answer 1

```java
public class MaxDifference {
    public static void main(String[] args) {
        int[] numbers = {2, 5, 9, 3, 1, 12, 6, 8};

        int maxDifference = findMaxDifference(numbers);
        System.out.println("Maximum difference: " + maxDifference);
    }

    public static int findMaxDifference(int[] numbers) {
        if (numbers == null || numbers.length < 2) {
            throw new IllegalArgumentException("Array must contain at least 2 numbers");
        }

        int minNumber = numbers[0];
        int maxDifference = numbers[1] - minNumber;

        for (int i = 2; i < numbers.length; i++) {
            if (numbers[i - 1] < minNumber) {
                minNumber = numbers[i - 1];
            }

            int currentDifference = numbers[i] - minNumber;
            if (currentDifference > maxDifference) {
                maxDifference = currentDifference;
            }
        }

        return maxDifference;
    }
}
