From Python Documentation: An except clause may name multiple exceptions as a parenthesized tuple, for example except (IDontLikeYouException, YouAreBeingMeanException) as e: pass Or, for Python 2 only: except (IDontLikeYouException, YouAreBeingMeanException), e: pass Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated and does … Read more
This is bad practice for two reasons: Normally, cleanup kind of actions … should also be executed when your code doesn’t fail; right? But if you only put it into the catch … cleanup isn’t called when no exception is thrown! Beyond that: the above will not call cleanup() for subclasses of Throwable that are … Read more
Probably, because of using getString() method, just use while parsing optString() method instead of getString() .getString(“Rate”); –> .optString(“Rate”); /** * Returns the value mapped by {@code name} if it exists, coercing it if * necessary, or throws if no such mapping exists. * * @throws JSONException if no such mapping exists. */ public String getString(String … Read more
Yes, if you don’t intend to handle or rethrow exceptions, you shouldn’t catch them.
The block: catch (Exception ex) { System.out.println(“NumberFormatException”); } will catch all the exceptions, as the Exception class is the base class for all the exceptions. When you catch Exception, you catch all the exceptions that extend Exception, which, all the exceptions do. Hence it produces the error that RuntimeException has already been caught
Assuming you have enough memory: try { std::vector<std::vector<double>> vec(5000000, std::vector<double>(5000000)); // … } catch (std::bad_alloc const& e) { // … }
Use a try catch block. var serversToTry = new []{“Server1”, “Server2”}; foreach (var server in serversToTry) { try{ //connect to server return; //if you made it this far, connection succedded. } catch (Exception e) { //log e if you want } }
