What will be the result of executing the following code? 1. boolean a = true; 2. boolean b = false; 3. boolean c = true; 4. if (a == true) 5. if (b == true) 6. if (c == true) System.out.println("Some things are true in this world"); 7. else System.out.println("Nothing is true in this world!"); 8. else if (a && (b = c)) System.out.println("It's too confusing to tell what is true and what is false"); 9. else System.out.println("Hey this won't compile");

  1. The code won't compile

  2. "Some things are true in this world" will be printed

  3. "Hey this won't compile" will be printed

  4. None of these


Correct Option: D

AI Explanation

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

Option A) The code won't compile - This option is incorrect. The code will compile without any syntax errors.

Option B) "Some things are true in this world" will be printed - This option is incorrect. The code will not reach the line that prints this statement because the conditions in the if statements are not met.

Option C) "Hey this won't compile" will be printed - This option is incorrect. The code will compile successfully.

Option D) None of these - This option is correct. The correct answer is none of the above.

The code will execute as follows:

  • Line 1: a is assigned true.
  • Line 2: b is assigned false.
  • Line 3: c is assigned true.
  • Line 4: The condition a == true is true, so the code proceeds to the next line.
  • Line 5: The condition b == true is false, so the code does not proceed to the next line.
  • Line 6: The condition c == true is true, so the code prints "Some things are true in this world".
  • Line 7: The code does not reach this line because the previous if statement was executed.
  • Line 8: The code does not reach this line because the previous if statement was executed.
  • Line 9: The code does not reach this line because the previous if statement was executed.

Therefore, the output will be "Some things are true in this world". None of the given options correctly describe the output, so the correct answer is D) None of these.
