Exam 1z0-808 topic 1 question 186 discussion

Answer is D. To test: public static void main(String[] args) { int a = 3; int b = 2; int c = 1; int r1 = a * b / c + 1; int r2 = a / b * c + 1; int r3 = a * (b / (c + 1)); System.out.println(r1 + " : " + r2 + " : " + r3); }

The correct answer is the letter D, remembering that we can divide "int" types even if there is leftover, dividing 3 by 2 would give "1.5" but as the whole number it cuts the decimal places getting "1" and making the code compile normally. Just doing the result of "r1" and "r2" you can already have the result without having to calculate "r3", the OCA test asks questions like this for you to waste time with distractors and time in a test that requires attention in every question is gold.
