[determinator]

Hey!
why answer option:
for (Blogger b: loader) {b.blog ("Hello from textbook"); }
is it correct?

after all, the condition explicitly says:
"Assume that data refers to the data that needs to be blogged."

data stored in a variable named "data" MUST be posted on a blog.

And in this answer they post completely wrong data on the blog:
"Hello from textbook".

Yes, it is correct. The data variable that you are referring to is the method parameter name. That is what the problem statement says, "...blog(String data) method of a blogging service...". As per the assumption, whatever this data variable points to will be blogged by the blog(String data) method.

When you call b.blog ("Hello from textbook"); , b is a reference to the blogging service and the String "Hello from textbook" will be assigned to the data variable of the blog method. In other words, within the blog method data will point to "Hello from textbook" and that will be blogged.

just explain why this question?

how could i know that loader.iterator() is correct if no mention about it in the PDF of mister Deshmukh??

the only mention about service loader are about modules and its very short

"Remember that java.util.ServiceLoader implements java.util.Iterable. Iterable" is not even mentionned in his pdf

If you have the PDF or Kindle, you can just search for a word by doing control F. If you have hard copy, you can look it up in the index. As you can see, it is explained in detail. You need to read it.

Note: If this is the book that you are referring to please refrain from mangling the name of the author. It is disrespectful. You wouldn't like people screwing up your name, would you?
