Select the second method of the publication: Version n (n ≥ 3)

After work today, I continued to read "UML basics, cases and applications (the third edition)" on the bus. The more I see it, the more I feel open. I had no clue in the vast UML teaching materials and did not know how to choose it. Later I was attracted by the three words "the third edition" on the cover of this book and decided to give it a try, it turns out that you are very eye-catching ~~~

I have read many books of version n, the most famous of which is mankun's "economic principles (the third edition)" and Sun's "Java2 core technology (version 5th)". The former is probably the best textbook I have ever seen. As mankun expected in the preface, I do not need certain concepts or formulas of underline during reading. I admire mankun's lecture on the high quality of water products. Needless to say, thinking in Java is the opposite. Many people choose to step from it to Java.

The motivation for multiple revisions is actually from the most authentic market demand, rather than the author's painstaking efforts to improve product supply without any reason. Therefore, this "version n" can be regarded as a self-issued but credible Award by the author. This proves the old saying of Economics: The market is an invisible hand. This hand also knows how to present awards :)

P.s. I didn't have any experience in getting started with technical teaching materials, so I had to buy them. Since several times of domestic career patchwork Masters (ctrl c/V master), it will no longer touch domestic teaching materials. This may be mean, but the truth is the truth. Let's leave it alone. Which domestic publishing house has the technical power to look at QC? As a result, he switched to foreign language translation and began to try it out at random. The translation of foreign languages is of course not well written (or poorly translated), so you can only accumulate experience on your own. Later, I gradually concluded that as long as I recognize those large publishers (such as Hz books and Mc Graw Hill), I will certainly not regret it.
