Java SE 7: Catching Multiple Exceptions

In Java SE 7 and later, a single catch block can handle more than one type of exception. This will avoid the code duplication.

For ex: Before Java SE 7, we would write the following code to catch multiple exceptions.

catch(IOException ex){
logger.log(ex);
throw ex;
} catch(SQLException ex){
logger.log(ex);
throw ex;
}

The same can be written as below in Java SE 7 and later which will avoid the duplicate code.

catch(IOException|SQLException ex){
logger.log(ex);
throw ex;
}

multiple exceptions are separated by vertical bar (|).

Note: If catch block handles more than one exception, then the catch parameter is implicitly final. So we can not assign any new value to the parameter (ex in the example).
