Given the code fragment: ``java public static void main(String[] args) { int j = 0; int ii = 7; for (int i = 0; i < ii; i = i + 2) { j = j + i; } System.out.print(ii + " " + j); } `` What is the…

Question

public static void main(String[] args) {
 int j = 0;
 int ii = 7;
 for (int i = 0; i < ii; i = i + 2) {
 j = j + i;
 }
 System.out.print(ii + " " + j);
}

Options

• A0 2 4
• B0 2 4 6
• C2 4
• DCompilation fails.

• A
  71% (15)
• B
  10% (2)
• C
  14% (3)
• D
  5% (1)

Explanation

Tracing through this code reveals that the marked answer A is actually incorrect - this appears to be a flawed exam question.

What the code actually does:

After the loop: ii = 7, j = 12.

System.out.print(ii + " " + j) outputs 7 12.

Why none of the choices are correct:

• A (0 2 4) - incorrect; that would require printing i inside the loop with ii < 6, neither of which is true here
• B (0 2 4 6) - those are the values i takes, but they aren't what gets printed
• C (2 4) - no path produces this
• D (Compilation fails) - the code is syntactically valid Java

The actual answer is 7 12, which is not among the choices. This is a defective question - either the print statement or the answer choices contain a typo. When you encounter a question like this on an exam, trust your loop trace over the listed choices. The key skill being tested is tracking i and j separately through each iteration.
