Purpose of FINALLY Block

[tal.benavraham]

finally block
- it handles uncatched exceptions.
- this must be followed with the try and catch block.
- if try block throw an exception then no other catch block handle that exception. now finally block executes that exception.
example:

try {
//it throws a zero by division error

}
catch(NullPointerException)
{
// it throws NullPointerException instead of Zero by division error
}
finally{
printStackTrace();
}
- in the above example no catch statement to handle the exception i.e throw by the try then finally block can handle that exception by using the printstacktrace() method. printstacktrace(), which handles any other exption.
main advantage is to be finally block must be executed.

note:dont enter any statement between try,catch and finally block even System.out.print() also. if u use compiler gives an error

1) please note that the finally block will ALLWAYS be executed, no matter what. not just if an exception was not caught.
2) what happends if an exception is thrown from within the finally block? - aha: the execution of the finally code will stop and the exception will be thrown out of the current function!

the Finally is to ensure tht the code enclosed with in this block is xecuted ever if when our program teriminates due uncatched xception
