Can we catch more than one exception in single catch block code example

Example: Can we catch more than one exception in single catch block

From Java 7, we can catch more than one exception with single catch block. 
This type of handling reduces the code duplication.

When we catch more than one exception in single catch block , 
catch parameter is implicity final. We cannot assign any value to catch 
parameter.

Ex : catch(ArrayIndexOutOfBoundsException || ArithmeticException e){
20
}

In the example e is final we cannot assign any value or 
modify e in catch statement
