White Box Testing

Given the following method in Java, which finds the maximum value in an array of integers.

public static int maximumValue(int[] a) {

if (a != null && a.length > 0) {

int max = a[0];

for (int i = 1; i < a.length; i++) {

if (a[i] > max) {

max = a[i];

}

}

return max;

}

return Integer.MIN_VALUE;

}
