Exception handling syntax

<p>Exception handling syntax is the set of keywords and/or structures provided by a computer <a href="/facts/Programming_language/cWTYbgWa">programming language</a> to allow <a href="/facts/Exception_handling_(programming)/XM8EsBpg">exception handling</a>, which separates the handling of errors that arise during a program's operation from its ordinary processes. Syntax for exception handling varies between <a href="/facts/Programming_language/cWTYbgWa">programming languages</a>, partly to cover semantic differences but largely to fit into each language's overall <a href="/facts/Syntax/6PxSV98p">syntactic structure</a>. Some languages do not call the relevant concept "<a href="/facts/Exception_handling/VrJxgb9r">exception handling</a>"; others may not have direct facilities for it, but can still provide means to implement it.
</p><p>Most commonly, error handling uses a try...[catch...][finally...] block, and errors are created via a throw statement, but there is significant variation in naming and syntax.
