Exception handling syntax varies between programming languages in order to cover semantic differences.
The syntactic structure of programming languages requires that the try/catch block is expressed somewhat differently from one language to the next.
Some languages do not call this concept
exception handling, while others may not have direct facilities for it, but can still provide a means for implementing it.
Most commonly, error handling uses a
try...[catch...][finally...]
block, and errors are created by means of a throw statement.
