You know, looking back at your post history, I'm going to recommend the most helpful tutorial I can think of for the balance of your time in computer science:

If you refuse to make any effort to find information and figure things out on your own, you may as well just pick a different subject to study altogether.

Read the stickies at the top of this forum, it will keep you busy for quite a while; and yes, like Ezzaral said, putting in a bit more effort would be beneficial for you as well as us.

Since two of the forum's senior guys have already posted onto this (one a mod and the other a featured poster) there's no need for me to do this but since I feel that one point escaped both of theirs attention I would like to comment on that. Did I see you asking for free ebooks ? Well as it happens there are some of the authors that I know of who offer some of their books for free on the net, like Bruce Eckel, Elliote Rusty Harold etc and there might be many more, don't expect everything to be free of cost. The author who's book you are so wanting to read put in months and months of hardwork researching on the subject so that readers shouldn't get incorrect information. There were several reviewers at the publishers who went over and over again filtering the material so that you not only get correct information you only get what you need to and none of the extra stuff. There might be authors who might be writing as an extended activity, but I believe for many of them thats the sole way of earning bread. So give the author whose collected information you want so desparately to access some credit for his work (and the men at the publishers too), and BUY the book !!!

Also I remember you being told many times to drop your habit of those irritating commas that you use while posting and not use chat speak like stuff. Give some attention to that, or do you want a free ebook on "dropping IM speak and writing proper english" too.
