Given the code fragment: boolean checkOut = true; int days = 0; while (checkOut) { days++; if (days > 3) { checkOut = false; } } System.out.print (days); What is the result?

The correct answer is B. 4. B (4) is correct because days increments before the condition is checked - so when days reaches 4, the condition days > 3 is finally true, checkOut is set to false, the loop exits, and 4 is printed. A (2) is wrong because the loop runs far more than two iterations - it only…

Explanation

B (4) is correct because days increments before the condition is checked - so when days reaches 4, the condition days > 3 is finally true, checkOut is set to false, the loop exits, and 4 is printed.

A (2) is wrong because the loop runs far more than two iterations - it only exits once days exceeds 3, not when it equals 2. D (3) is a common trap: the condition is days > 3 (strictly greater than), not days >= 3, so the loop does not stop at 3. C (infinite loop) is wrong because checkOut is eventually set to false once days > 3, giving the loop a guaranteed exit.

Memory tip: When you see > in an exit condition like days > 3, the variable must pass the threshold - think "the loop needs one extra step to cross the line," making the final value one higher than the number in the condition (3 + 1 = 4).
