We all know that now is the Internet age, the age of artificial intelligence, from shopping, taxi, takeout, etc. everywhere. The development of these software requires a large number of programmers and lines of code. In the future, we need enough programmers to support, provide us with technology, and bring convenience. Therefore, the demand for programmers is still rising. When there is demand, the salary is definitely not low. To learn any language, interest is the most important. Now Java is the hottest computer language at the moment and many people learn it. There are many people who want to learn. So what do you learn about java programming?
The java foundation of the first stage mainly includes introduction to Java development, arrays, object-oriented, common classes, exceptions, collections, I/O streams, multi-threading, networking, reflection, and there are quite a lot of content. There are no shortcuts to learning. There is no talent. Remember to memorize, memorize, and practice more when entering the door of development. In-depth understanding can be slowly explored and learned in future work.
The second stage, JavaWeb, is an advanced stage. Students can master the basic grammar, data types and various operators of Java, and can write some operations-related programs at the beginning;
The third stage of the Java framework, the framework is another way of storing data in the program, which is more flexible than directly using arrays for storage, and is widely used in projects. At the same time, the data structure and algorithm involved will be studied in depth, which has a qualitative improvement to the technical depth of the students;
The fourth stage Java + cloud data, the evolution of billion-level concurrent architecture, Linux foundation, building tomcat environment, and big data development cloud computing and other advanced Java tutorials are high-end knowledge of Java technology. Among them, interspersed project actual combat drills, enterprise real projects are for students to apply learning and conduct the "second learning" of the knowledge system.
1. In the study, you must be able to summarize the learning methods (master the grammar rules, and then apply by analogy).
2. In the process of learning, it is best not to just stay on the surface of Java, not to run the results from the examples on the copy of the book. It should be noted that even a simple example must be patient to ponder, debug, and modify.
3. In the process of learning, you must do it yourself and try to write code instead of just watching videos and notes. Many things and experiences must be done by yourself to truly belong to yourself.
- In the process of learning Java, you may encounter various problems that are not easy to solve. You should first learn to think about the solutions to the problems yourself, and then you can also ask your classmates and the Internet for help.
