1Z0-811 Primitives, Strings and Operators Practice Question
Exhibit
Refer to the exhibit.
public class OperatorTest {
public static void main(String[] args) {
int x = 3;
int y = ++x * x++;
System.out.println(x + "," + y);
}
}What is the output of the following code?
int x = 5; int y = 16;
System.out.print(x + "," + y);
⚠ Common exam trap
This question tests simple variable initialization and output. The trap is that candidates might overthink and assume some operation changes the values, but since no operations are present, the output is simply the initial values. The comma in System.out.print is just a string literal, not a separator for multiple arguments.

Correct answer & explanation
✓
5,16
The code initializes `int x = 5;` and `int y = 16;` and then prints them using `System.out.print(x + "," + y);`. Since there are no operations that change the values, the output is simply the initial values: 5,16. Therefore, option A is correct.
