Preface It's almost six years since I graduated from college. I have been engaged in development and training in these six years. In contrast, I have been involved in training for a longer time. Due to the characteristics of the work, I encountered a variety of students, encountered a series of problems in learning programming, and many confused times, hoping to write a book, summarize relevant issues and share your experience with you. Of course, some of the knowledge is just my personal opinion, and I hope you can actively correct it, help Programming beginners, and Program Developers can deeply understand basic concepts, learn programming better, and engage in development work. There is always a name for writing a book. Let's name it the story of Java programming. It mainly uses a popular language to explain the following: 1, What is program design? 2, Java-related basic syntax and Applications 3, How to establish the basic program logic and other programming and Java-related issues, this book is intended to be written in the form of online serialization, it is estimated that the writing cycle will be relatively long, I hope I can do my best for the software development industry.
