Is using try catch is good experience in coding practice
here is a detailed answer .
Best practice is that exception handling should never
hide issues. This means that try-catch blocks should be extremely rare.
There are 3 circumstances were using a try-catch makes
sense.
1. Always deal with known exceptions as low-down as you
can. However, if you're expecting an exception it's usually better practice to
test for it first. For instance parse, formatting and arithmetic exceptions are
nearly always better handled by logic checks first, rather than a specific
try-catch.
2. If you need to do something on an exception (for
instance logging or roll back a transaction) then re-throw the exception.
3. Always deal with unknown exceptions as high-up as you
can - the only code that should consume an exception and not re-throw it should
be the UI or public API.
