Is resource release guaranteed in the finally block after executing try/catch?

Answer from AI

In Java, the finally block is guaranteed to execute after the try block and any associated catch blocks, except in certain critical situations such as:

  • If the JVM terminates abruptly (for example, System.exit() is called inside try or catch).
  • If the thread is interrupted or killed before executing finally.
  • If an infinite loop occurs in the try or catch block, or the program hangs.

Under normal circumstances, when execution reaches the end of the try or catch block, the finally block will execute and release resources, such as closing files or connections.

Example:

try {
    // work with resource
} catch (Exception e) {
    // handle exception
} finally {
    // resource release, guaranteed to execute
}

Therefore, the finally block is a reliable place for resource cleanup, but not absolute if the program terminates abruptly.
