B Correct answer
Explanation

System.exit() immediately terminates the JVM, bypassing the finally block. Only Hello world prints before exit(). The finally block never executes because System.exit() halts the program abruptly, skipping all normal cleanup including finally blocks.

AI explanation

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

Option A) Hello world \n Goodbye world - This option is incorrect because the \n character represents a newline character, which means that "Goodbye world" would be printed on a new line. However, the code snippet does not include the \n character, so the output will not have a newline.

Option B) Hello world - This option is correct. The code snippet will print "Hello world" because the statement System.out.println("Hello world"); is executed before the System.exit(0); statement. The System.exit(0); statement terminates the program, so the finally block is not executed.

Option C) Compilation Error - This option is incorrect. The code snippet does not contain any syntax errors, so it will compile successfully.

Option D) Run Time Error - This option is incorrect. The code snippet does not contain any statements that would cause a runtime error.

The correct answer is B. The output of the code snippet will be "Hello world" because the System.out.println("Hello world"); statement is executed before the program terminates.
