hello~
I am Jaehwan Lee, the author of the book [Introduction to Java Programming by Jaehwan Lee].
Are you all having a hard time studying in this hot weather?
I have some good news for you all to cheer you up.
The course you are currently listening to is a lecture on the contents of the book [Pre-requisite Class], which is a separate appendix to the book [Lee Jae-hwan's Introduction to Java Programming]...
Thinking that we would not only provide the lectures for free, we also uploaded the [Pre-requisite Class] book, which is a separate appendix, in e-book format for free on online bookstores.
Since it is a separate appendix to the official book, it was officially registered in an online bookstore.
This is not a sample view, this is the full book.
(If it's a book that's not worth reading, it won't even be listed on an online bookstore.)
Below are links to bookstores where you can download the book.
