First: what happens in your example if array.length=2^n-1, where n is the number of bits used to represent i? How would you increment ++i then? Second: for (int i = 0; i <= array.length-1; i++) {} array[0..array.length-1] I should note that from mathematical point of view, "<" is not a relation of order, as it lacks reflexivity (meaning a<b and b>a does not imply a==b). Only <= and >= are relations of order, as they are also reflexive (as a<=b and b<=a implies a==b).
