Saikrishna,

The following line throws java.lang.ArithmeticException: / by zero
int i = 4541 / 0 ;

But you are not catching the exception so it just comes to finally block.
Try the following:

in your code when exception occurs at line
int i = 4541 / 0 the control jumps to finally block
this is why exception is not thrown.
As you know finally block always executes and
When exception is thrown at line i = 4541 / 0
and you donot handle it line System.out.println(i)
will never execute and then finaly block is executed.



check code below which throws Exception

In your case, an Arithmetic exception is thrown in a catch clause. Then there is a finally clause which will be executed. Since finally has a return statement, this overrides any exception. That means the expection that was raised in catch block is lost after the return statement.

Yes, the JLS would say that this is is a case of the finally block "ending abruptly" and that the original reason is lost.

Yes. When you use return or throw in finally block it will show a warning message called "finally block does not complete normally".

Always remember before printing the RuntimeException it executes the finally block (if anything defined). In this case since we had the return statement in finally compiler didnt get a chance to print the RuntimeException!
