class MyException extends Throwable{}
Is this MyException checked exception or what?
void myMethod() throws MyException{
throw new MyException3();
This method is throwing new MyException3 but the throws statement mention MyException?
Is it valid to mention some Exception with throws statement and then actually throwing some other Exception in the body? I mean can they differ?
Thanks a lot;

What do you think?
void myMethod() throws MyException{
throw new MyException3();

Myexception3 is also there in the code.

You might want to go through this first before attempting questions on exceptions -

After this this code:
Code: Select all
void myMethod( ) throws MyException{
throw new myException3( );
}
Which exception actually gets thrown ? Is it myException3 or myException? If myException is thrown, will a catch(myException3 e) block effectively catch it?

The compiler won't actually tell me if it's myException3 that gets thrown or myException that gets thrown.

Of course not. Exception is thrown at run time. So you need to put your code in a class and call it from main. Then execute the class and you will see the result on the command line.

If MyException3() comes before the MyException() (switch the order of catch block), what gonna happen?
