Java final, finally and finalize - GeeksforGeeks

3 weeks ago - In Java, the keywords "final", "finally" and "finalize" have distinct roles. final enforces immutability and prevents changes to variables, methods or classes. finally ensures a block of code runs after a try-catch, regardless of exceptions.

What is the point of the "finally" clause in Java?

You often perform clean up tasks in the finally block. Say you opened a connection, an exception occurred, now you can perform proper connection clean up in finally. The finally block is guaranteed to be called. If your clean up code wasn't called, you may introduce a memory leak. If youre using an object that implements Closable, you probably would call the close method in finally. Finally is often used when dealing with "resources", like files, or network requests.

What is the purpose of `finally` in `try/catch/finally`?

The finally part executes even if the exception was not caught (because it wasn't the type matched by the catch or because there was no catch clause at all), if the catch clause re-throws the exception or throws another exception, or if either of the clauses returns or otherwise jumps out of the current block.

java - Why use finally - Stack Overflow

They differ if

the try-block completes by throwing a java.lang.Throwable that is not a java.lang.Exception, for instance because it is a java.lang.Error such as AssertionError or OutOfMemoryError.
the try-block completes abruptly using a control flow statement such a continue, break or return
the catch-block completes abruptly (by throwing any throwable, or using a control flow statement)

More generally, the java language guarantees that a finally block is executed before the try-statement completes. (Note that if the try-statement does not complete, there is no guarantee about the finally. A statement might not complete for a variety of reasons, including hardware shutdown, OS shutdown, VM shutdown (for instance due to System.exit), the thread waiting (Thread.suspend(), synchronized, Object.wait(), Thread.sleep()) or being otherwise busy (endless loops, ,,,).

So, a finally block is a better place for clean-up actions than the end of the method body, but in itself, still can not guarantee cleanup exeuction.

finally block executes always.

finally block is used for cleanup, like to free resources used within try/catch, close db connections, close sockets, etc.. even when an unhandled exception occurs within your try/catch block.

The only time the finally block doesn't execute is whensystem.exit() is called in try/catch or some error occurs instead of an exception.

The error in the description above means when Java application exit with conditions like Out Of Memory error. I see some downvotes :( for this reason it seems.
