What results from attempting to compile and run the following code? public class Ternary { public static void main(String args[]) { int a = 5; System.out.println("Value is - " + ((a < 5) ? 9.9 : 9)); } }

  1. prints: Value is - 9

  2. prints: Value is - 5

  3. Compilation error

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In Java's ternary operator, if the second and third operands have different numeric types, binary numeric promotion applies. Here, the expression's overall type is promoted to double, converting 9 to 9.0, resulting in Value is - 9.0. None of the specific print distractors matches.

AI explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) prints: Value is - 9 - This option is incorrect because the code will not print "Value is - 9". Instead, it will print "Value is - 9.0" because the expression (a &lt; 5) ? 9.9 : 9 evaluates to 9.9, which is a double value.

Option B) prints: Value is - 5 - This option is incorrect because the code will not print "Value is - 5". The value of the variable a is 5, but the ternary expression (a &lt; 5) ? 9.9 : 9 evaluates to 9.9, not 5.

Option C) Compilation error - This option is incorrect because the code will compile successfully without any errors. The code uses valid Java syntax.

Option D) None of these - This option is correct because the code will print "Value is - 9.0". The ternary expression (a &lt; 5) ? 9.9 : 9 evaluates to 9.9, which is a double value. The output will include the decimal point and ".0" because it is a double value.

Therefore, the correct answer is D) None of these.
