In what cases will the finally section not execute?

Answer from AI

The finally section in Java will not execute in the following cases:

If the JVM terminates abruptly — for example, when calling Runtime.getRuntime().halt() or due to serious errors causing JVM crash.
If the thread executing the try-finally block was interrupted or stopped before finally executes — for example, when using deprecated methods like Thread.stop().
If System.exit() is called within a try or catch block, the JVM will terminate, and finally may not execute.

Example where finally will not execute:

try {
    System.exit(0);
} finally {
    System.out.println("This code will not execute");
}

Under normal conditions, during a regular completion of try/catch block, finally always executes, even if a return statement or an exception occurs inside try/catch.
