1Z0-811 Primitives, Strings and Operators Practice Question
Evaluate the following expression: int x = 5; int y = (x > 5) ? 10 : 20; What is y?
⚠ Common exam trap
Oracle often tests the ternary operator by setting the condition to a borderline value (like equality) to see if candidates mistakenly think the true branch is selected when the condition is false.

Correct answer & explanation
✓
20
The ternary operator `(x > 5) ? 10 : 20` evaluates the condition `x > 5`. Since `x` is 5, the condition is false, so the expression returns the value after the colon, which is 20. This value is assigned to `y`, making `y` equal to 20.
