Catch Multiple Exceptions
Did you know that Exceptions can be chained?
You can chain exception catch!
Did you know that Exceptions can be chained?
apex
try {
// do some stuff
} catch (Exception a) {
// logic after A exception
} catch (Exception b) {
// logic after B exception
}It can be useful if you want to implement different strategies depending on a thrown exception:
apex
try {
Example.doSomethingRisky();
} catch (NullPointerException nullProblem) {
Helper.callSystemAdmin();
} catch (DmlException insertProblem) {
System.debug('It\'s not a big deal!');
}It also works with custom exceptions:
apex
try {
Example.doSomethingRisky();
} catch (MyQueueStackException customException) {
System.enqueueJob(new EmergencyQueueable());
} catch (LastHopeException hopeException) {
GodClass.sendForHelp();
}
