In the given example statements demonstrate three catch blocks, but you can have
any number of them after a single try.
If an exception occurs in the
protected code, the exception is thrown to the first catch block in the
list. If the data type of the exception thrown matches ExceptionType1,
it gets caught there. If not, the exception passes down to the second
catch statement. This continues until the exception either is caught or
falls through all catches, in which case the current method stops
execution and the exception is thrown down to the previous method on the
call stack.
try { //Protected code }catch(ExceptionType1 e1) { //Catch block }catch(ExceptionType2 e2) { //Catch block }catch(ExceptionType3 e3) { //Catch block }
