1Z0-811 Arrays and Methods Practice Question
Exhibit
Refer to the exhibit.
public class VarargsExample {
public static void main(String[] args) {
print(1, 2, 3);
print(new int[]{4, 5, 6});
}
public static void print(int... nums) {
for (int n : nums) {
System.out.print(n + " ");
}
}
}What is the output?
⚠ Common exam trap
Many exam-takers assume each method call starts on a new line, but the `print` method does not output a newline, so the output is concatenated on the same line.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
1 2 3 4 5 6
The code uses a varargs method `void print(int... nums)` which accepts zero or more int arguments. When called with `print(1, 2, 3)` and `print(4, 5, 6)`, each call prints the passed integers separated by spaces, resulting in "1 2 3 " and "4 5 6 " on the same line because there is no newline between calls. Thus the output is "1 2 3 4 5 6".
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
1 2 3
Why it's wrong here
The second call is also executed, so it prints more.
- ✓
1 2 3 4 5 6
Why this is correct
The first call prints 1 2 3 (with spaces), and the second call prints 4 5 6 on the same line.
- ✗
1 2 3 4 5 6
Why it's wrong here
No newline is printed between calls because the print method does not output a newline.
- ✗
Compilation error: ambiguous method call
Why it's wrong here
There is no ambiguity; the method can accept both forms.
