Method Structure - Elite Pattern

Every clean method follows this structure:

public int findMaximumSubarraySum(final int[] numbers) {

    if (numbers == null || numbers.length == 0) {
        throw new IllegalArgumentException("Input array cannot be null or empty");
    }

    int currentSum = numbers[0];
    int maximumSum = numbers[0];

    for (int index = 1; index < numbers.length; index++) {
        int value = numbers[index];
        currentSum = Math.max(value, currentSum + value);
        maximumSum = Math.max(maximumSum, currentSum);
    }

    return maximumSum;
}

Predictable structure signals seniority.
