1Z0-829 Controlling Program Flow Practice Question

How many times does the following loop execute? int i=0; while(i<5) { System.out.println(i); i++; }

⚠ Common exam trap

The trap here is that candidates often miscount the iterations by starting at 1 instead of 0, or forget that the condition is checked before each execution, leading them to choose 4 or 6 instead of the correct 5.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The loop starts with i=0, checks the condition i<5 (true), prints i, then increments i. This repeats until i becomes 5, at which point i<5 is false and the loop terminates. Thus, the loop executes exactly 5 times (i=0,1,2,3,4).

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
0
Why it's wrong here
The condition i<5 is initially true, so the loop executes.
✗
6
Why it's wrong here
The loop stops when i becomes 5, so it runs 5 times.
✓
5
Why this is correct
The loop runs for i=0 through i=4, which is 5 iterations.
✗
4
Why it's wrong here
The loop runs 5 times, not 4.
