Last Update:
What is the output of the following code?
1: public class TernaryTester {
2: public static void main(String[] args) {
3: int x = 5;
4: System.out.println(x > 2 ? x < 4 ? 10 : 8 : 7);
5: }}
❌ A. 5
❌ B. 4
❌ C. 10
✅ D. 8
❌ E. 7
❌ F. The code will not compile because of line 4.
Explanation:
Although parentheses are not required, they do greatly increase code readability, such as the following equivalent
statement: System.out.println((x > 2) ? ((x < 4) ? 10 : 8) : 7)
We apply the outside ternary operator first, as it is possible the inner ternary expression may never be evaluated. Since (x>2) is true, this reduces the problem to: System.out.println((x < 4) ? 10 : 8)
Since x is greater than 2, the answer is 8
