Objective

Since March last year I began to read "effective Java second Edition", of course, I read the Chinese version of the; Maybe I can not understand the ability, for the content of the book always feel difficult to understand; take the first chapter of the content " Create and destroy objects "to say, this is the most I read the chapter, presumably the reason everyone also understand, every time I can not read down, I began to read from the beginning, so, now I am the first chapter of this book is the most familiar." Later, on the Internet, I saw a netizen said that this book and most of the translation of books, for some of the content of the original translation is not very smooth, so it will lead to the reading of the people feel difficult to understand, so I ventured the English version of the comparison to see, found that it is easier to understand, So at last it took a month or two to finish the whole book. (Well, the real situation is that I've been involved in several projects this time, so I've accumulated a lot of programming experience, so there's a little bit of thought and understanding of the "best practices" recommended in the book "Effective Java".) ）
