Many people choose the programmer industry, and most people think that technical work is interesting and not monotonous, with a lot of money and development. This is true to some extent, but the treatment depends on your professional level and ability to do the job.
Java is an excellent programming language, and its popularity has remained unabated since its birth, and it is deeply loved by developers. I started with Java learning, and the 7 pictures let you practice solid professional basic skills.
1. Basics of Java
This picture is from the introduction of Java development, basic concepts of Java programming, object-oriented knowledge and application, enumeration, internal classes, arrays, assertions, common classes, exception handling, annotations, reflection, coding methods, time processing, syntactic sugar, JAVA copy , Generics and more than a dozen commonly used Java knowledge points have been summarized, and I hope it will be helpful for those who are getting started with Java.
Two, Java SE
This picture summarizes Java SE from four categories: understanding of Java, basic grammar, JVM virtual machine, and JUC concurrent programming. This part has a lot of content, so you can collect it and learn it slowly. It is recommended to combine theory and practice. If beginners are too entangled in theoretical knowledge, they will often be discouraged because of boring. It is recommended to type more codes. If you type too much, you may have an epiphany one day.
3. New features of Java8
This picture summarizes and analyzes lamda expressions, refactoring/testing and debugging, replacing null with optionals, new date and time APIs, functional programming skills, streams, default methods, functional thinking, etc. The content is rich, and I hope that after reading it, I can quickly grasp the new features of Java8.
4. Front-end thinking
From the 12 questions and answers, this picture of front-end thinking can help most of the small partners who are engaged in front-end work to solve their doubts. Do you want to improve development efficiency? Want to brush up on the basics? Want to learn framework & library technology? Want to dive deeper into the front end? Want to learn applets? Want to learn mini games? Want to learn data visualization, backend, database, server, APP? If you want to know the answers to these questions, just look at this picture.
5. Database table structure
He must have done something right for the database table structure diagram that was cloned and used by more than 1,000 people. If you also find this template useful, welcome to like and bookmark the clone one-click triple link.
6. SSM Technical
Architecture
This is a SSM technical framework diagram of the technical framework of SSM-based storage, persistence, data service and request distribution.
7. Microservice
