Apr 13, 2011 · Use exceptions rather than return codes. You can wrap exceptions in your own, if you like. It is perfectly reasonable to use exceptions for flow control -- in exceptional conditions. The usual recommendation is to avoid their use for ordinary flow control. Or sequential try/catches. But a single try/catch may be sufficient.

Feb 28, 2023 · In this article, we’ll explore all the possible combinations of try-catch-finally which may happen whenever an exception is raised and how the control flow occurs in each of the given cases. Control flow in try-catch clause OR try-catch-finally clause Case 1: Exception occurs in try block and handled in catch block

Jul 4, 2017 · I wrote an utility to create a CFG (Control Flow Graph) for a java method whose nodes are basic blocks instead of instructions. I could not consider exception throws to be edges in CFG. The reasons are that: Every instruction in try block can potentially throw exceptions / errors which can be handled by any of the nesting try-catch blocks.

Oct 12, 2017 · The exceptions should be used to signal errors in application. If you can avoid exception (eg checking if user specified correct file name using file.exists()) beforehand, then you should do that (unless it is really out of the normal logic flow and you just can't proceed).

We propose the analysis that estimates exception-induced control flow, and also propose exception flow graph that represents exception induced control flows. We show that a control flow graph can be constructed by merging an exception flow graph onto a normal flow graph.

Sep 16, 2008 · This paper presents an empirical study whose goal was to investigate the exception handling strategies adopted by Java libraries and their potential impact on the client applications. In this study, exception flow analysis was used in combination with ...

Sep 1, 1999 · The Factored Control Flow Graph, FCFG, is a novel representation of a program's intraprocedural control flow, which is designed to efficiently support the analysis of programs written in languages, such as Java, that have frequently occurring operations ...

Handling various complex scenarios and multi-layered exceptions was a crucial challenge. I honed my problem-solving skills to ensure the generated control flow graphs accurately reflected the intricacies of the code.

We present an algorithm to extract ow graphs from Java bytecode, including exceptional control ows. We prove its correctness, meaning that the behavior of the extracted control- ow graph is a sound over-approximation of the behavior of the original program.

Dec 27, 2016 · Exceptions are commonly used for flow control in Java, but how well do they perform compared to return values?
