Can multiple catch blocks of the same try catch finally statement be executed?
No we cannot execute multiple catch blocks for the same try statement. This is because in all cases in case of exception only once the catch statement is executed.

What is the difference between catch and finally block in Java?
If the type of exception that occurred is listed in a catch block, the exception is passed to the catch block much as an argument is passed into a method parameter. The finally block follows a try block or a catch block. A finally block of code always executes, irrespective of occurrence of an Exception.
What happens when you re-throw an exception in a catch block?
