Static method and exception

Question

I have file which is reading from file and deleting it.
delete is done by static method.
now i need to do like this if file is empty it should throw exception and delte the file.
so i added else like this
else{
throw new empty("Empty");
but it is only thorowing exception not deleting file.as that static code is unreachable after throwing exception.
any idea
