Looking at the question you asked, you should be interested in java, in fact you can I just saw a very good article about how to learn java, it’s a migrant worker introduce himself how to self-study java and find a job in Java, it describes his learning method and learning process, I hope it’s helpful to you.
I am a local migrant worker, living in the economically backward countryside, there is an older brother and a younger brother, parents are authentic farmers, sunrise and sunset, I grew up learning has been very good, from elementary school to the first year of high school, the results of the whole class has always been at the top, so I also successfully got into the province’s key high school, however, the beginning of each semester is the family’s most difficult time, each time the tuition fee, let the parents pay the tuition fee, the parents are very happy. Every time to pay tuition fees are let parents worry for a long time, the family in order to raise money for me to study, have borrowed a lot of money, so that I read in high school. I know I read to high school family has owed a lot of debt, in order to reduce the burden on the family, I chose to quit school.
In 2009, I dropped out of high school, in order to pay off the debt to the family, dry construction site workers, engaged in the processing of plastic products, water delivery workers and so on. Very low wages are very low, a month is more than 1,000, plus overtime pay a month to get a little more than 2,000, I sent home every month 800-1,000 yuan, to the end of 2011, a chance I came into contact with Java, I heard that the prospects for Java is quite good, the wage is astronomical relative to a migrant worker, so I bought a few books in the Xinhua bookstore! Java books, despite the hard work during the day, come back at night or insist on reading books, but there is too poor in the foundation of a lot of very do not understand, but still insist on looking at a book to see 1-2 hours of Java, looked at many of the basics are slowly learned, but those more difficult to understand, and then also bought some books on the framework, or do not see, so off and on for more than half a year, I feel that the foundation of Java are almost understand. The basis of their own Java are almost understand, but the framework is still not understand, there is a lack of project experience, see a lot of recruitment of Java programmers profile to project experience, relative to me a migrant worker to even get the framework do not understand, I want to find a Java job for me is simply a luxury. I just want to learn Java, and I don’t dare to think that I can work in Java in the future.
On one occasion, I saw an article on Baidu that encouraged me to introduce a Java expert in the absence of a basic friend how to teach yourself how to get started with Java, the article is very well written, contains how to learn, how to learn, he mentioned a method is to watch the video, because reading the book is really too boring and convoluted, a lot of us can’t read it, I really agree with this point, I read the book myself! I really agree with this point, I read the book myself for a long time to learn the basics. Once thought to participate in training, but tens of thousands of dollars in training fees to discourage me, my salary is so low, every month, and remittance of money to the family, coupled with the city consumption is relatively high, although only a few hundred left each month, but compared to the tens of thousands of tuition fees and four months of food and housing costs forced me to even dare not think about it. So I decided to watch the video, I went to search for Java video, although I sporadically find some Java video, but are not systematic. The most important thing is not even the project. Later I found a very good video, is the IT Learning Alliance this site a set of videos called <<Zero-Basic Java employment class >> tutorials are not bad, very complete. Also presented 11 top enterprise projects. The price is very reasonable, so I buy it.
Then I went to 51job crazy resume, because of my educational problems, junior high school graduates, seriously, no one will want me to big companies. So I head to all the small private companies, I hope their efforts pay off. I did not think a few days later, there will be an interview, but the first interview I failed, although I think the written test is very good, because I did before the preparation, but their requirements than strict, need to have a year of project experience, so I was not selected. I interviewed with a few companies one after another, and finally I was able to interview with a private company. The company was relatively small, and my position was a Java programmer. I think I’m more fortunate, the manager of my efforts, decided to Lv Yong me, the wage is 3500 a month, although I know that in Beijing 3500 can only over the biochemistry of subsistence, but I think I’m enough, compared to the previous wage is better, and later you can send more money home. I think as long as I continue to work hard. My salary will definitely double. Write this article out, I hope to make and I have no basis for friends have confidence, in fact, we do not have low self-esteem, we are not dumber than others, only we are willing to work hard, we will be just as successful.

Domain-driven design (DDD) is what teaches us how to make good software, and also how to make better use of object-oriented techniques. It gives us a new perspective on designing software, but it also leaves developers with a big problem: how to put domain-driven design into practice.VaughnVernon’s book, Implementing Domain-Driven Design, gives us a comprehensive answer.
Implementing Domain-Driven Design is a detailed discussion of how to implement DDD at both the strategic and tactical levels, and includes a wealth of best practices, design guidelines, and eclectic discussions of some of the issues. Divided into 14 chapters, Realizing Domain-Driven Design explains domains, bounded contexts, context mapping diagrams, and architectures in the strategic section of DDD, and entities, value objects, domain services, domain events, aggregations, and repositories in the tactical section. A fictional case study is presented throughout the book, which is very useful for illustrating DDD implementations.
Implementing Domain-Driven Design bridges the gap between DDD ideas and implementations and can be read by architects and programmers alike, as well as serving as a DDD reference book.
Author:VaughnVernon is a seasoned software craftsman with over 25 years of experience in software design, development, and architecture. He is an advocate of innovation to simplify software design and implementation. He has been programming in object-oriented languages since the 1980s, and applied domain-driven design to domain modeling in the early 1990s, when he used the Smalltalk language. He has experience in many business areas, including aviation, environment, geography, insurance, medicine, and telecommunications. Vaughn has also had great technical success, including the development of reusable frameworks and class libraries. He provides software consulting and speaking engagements worldwide, in addition to teaching courses on Implementing Domain-Driven Design in many countries.

Using practical examples to clarify the dry theory of algorithms, and focusing more on the cultivation of algorithmic design thinking, it is suitable for algorithmic introductory book.
This is an algorithm design course textbook adopted by many famous schools, emphasizing the use of practical examples to illustrate boring algorithm theory, and focusing more on algorithm design thinking rather than algorithm complexity analysis. The book takes a novel pedagogical approach to stimulate algorithmic thinking by analyzing real-world problems. In a clear, straightforward manner, the two authors guide students to analyze and define problems themselves and from there identify algorithmic design principles that apply to a given scenario. The book encourages readers to gain a deeper understanding of the algorithmic design process and to explore the application of algorithms to the broader field of computer science.
This book has the following features:
