finally

Another interview question which was expecting a true / false answer and I wasn't too sure. Duplicate In .NET, what if something fails in the catch block, will finally always get called? Does a finally block always run? Conditions when finally does not execute in a .net try..finally block Will code in a Finally statement fire if I return a value in a Try block? finally is executed most of the time . It's almost all cases. For instance, if an async exception (like StackOverflowException , OutOfMemoryException , ThreadAbortException ) is thrown on the thread, finally execution is not guaranteed.

I'm reviewing some new code. The program has a try and a finally block only. Since the catch block is excluded, how does the try block work if it encounters an exception or anything throwable? Does it just go directly to the finally block? If any of the code in the try block can throw a checked exception, it has to appear in the throws clause of the method signature. If an unchecked exception is thrown, it's bubbled out of the method. The finally block is always executed, whether an exception is thrown or not. Peter Lawrey A small note on try / finally : The finally will always execute unless

I found the following behavior at least weird : def errors(): try: ErrorErrorError finally: return 10 print errors() # prints: 10 # It should raise: NameError: name 'ErrorErrorError' is not defined The exception disappears when you use return inside a finally clause. Is that a bug? Is that documented anywhere? But the real question (and the answer I will mark as correct) is: What is the python developers' reason to allow that odd behavior? You asked about the Python developers' reasoning. I can't speak for them, but no other behavior makes sense. A function can either return a value, or it can

I'm wondering a bit about C++ try/catch/finally blocks. I've seen these commands with two underscores like __try. But MVSC 2010 projects also run without the underscores. So when do you need these underscores? Hans Passant On Windows, exceptions are supported at the operating system level. Called Structured Exception Handling (SEH), they are the rough equivalent to Unix signals. Compilers that generate code for Windows typically take advantage of this, they use the SEH infrastructure to implement C++ exceptions. In keeping with the C++ standard, the throw and catch keywords only ever throw and

This question already has an answer here: Multiple returns: Which one sets the final return value? 7 answers By reading all the questions already asked in this forum related to the topic above (see title), I thoroughly understand that finally gets always called. (except from System.exit and infinite loops). However, I would like to know if a return is called in a catch block and then another return is called from the finally block. For example: public static void main(String[]args) { int a = new TestClass().absorbeTheValue(); } int absorbeTheValue() { try { int a = 10/0; if (a > 0) return 4; }
