More than 800 pages of JAVA core explanation +DVD4G video tutorial, this is the best JAVA book I have ever bought. I closed all other JAVA books. And there are many examples in this book, and each line of code has comments. Enough to show the author's professional style. As a matter of fact, I have listened to the course of the author Li Xinghua before, which is very in line with the current actual development. The JAVA class I took in college was reviewed in the video class of MLDN. I support teacher Li's book! !
