Question

Inside Method A, there is method B. Method B throws exception, but method A compiled even it does not catch exception or throws exception, could it be possible?

Method B is something like as below:

MethodB() throws SomeException{
   if(Some)
        doneSomething
        return
   else if(some)
        donesomethingElse
        return 
   throw SomeException  
}

Answer 1

If the SomeException extends RuntimeException. Then you don’t need to catch it even if the signature looks like that.

Also note that you can just remove the throws SomeException in that case. Read more here.
