Catching Multiple Exceptions in Java 7
Jakob Jenkov |
In Java 7 it was made possible to catch multiple different exceptions in the same catch block. This is also known as multi catch.
Before Java 7 you would write something like this:
try { // execute code that may throw 1 of the 3 exceptions below. } catch(SQLException e) { logger.log(e); } catch(IOException e) { logger.log(e); } catch(Exception e) { logger.severe(e); } As you can see, the two exceptions SQLException and IOException are handled in the same way, but you still have to write two individual catch blocks for them.
In Java 7 you can catch multiple exceptions using the multi catch syntax:
try { // execute code that may throw 1 of the 3 exceptions below. } catch(SQLException | IOException e) { logger.log(e); } catch(Exception e) { logger.severe(e); } Notice how the two exception class names in the first catch block are separated by the pipe character |. The pipe character between exception class names is how you declare multiple exceptions to be caught by the same catch clause.
