Preface
According to relevant statistics, at present, the recruitment volume of Java posts is still the largest on large and small recruitment websites, which is basically more than three times that of other languages. Due to the current dominant position of Java, the number alone See, there are a large number of systems implemented by the Java language. So many systems are using Java. In addition, the Java language is relatively simple to get started, which is convenient for beginners to learn. This has also led to the continuous increase in the number of Java programmers.
Under such a form, the question of how Java programmers learn and grow has always attracted much attention. Even if people who start together at the same time go through different learning processes, the gap will gradually manifest. So how do you learn Java when you are senior? What technology stacks need to be mastered? How can I not be shot dead on the beach by the'back wave'? Don't worry! Lei Feng from the Internet (in my editor) collected a set of Alibaba's internal Java full-stack knowledge compilation and growth notes for everyone to learn from, and hope to be helpful to everyone!
Java from ignorance to entry
The first document has 499 pages of content, which is relatively basic, so I won’t do too much display. It is suitable for Xiaobai to watch and understand this document. Even if it is an introduction to Java, friends in need can help comment and forward, follow me The way to get it later is at the end of the article!
The following document is a comprehensive analysis of high-level core knowledge in Java, suitable for advanced learning of friends who are just getting started
Getting started with Java
- basis
- container
- Concurrent
- JVM
Computer network knowledge
For the study of computer network, I think it is enough to master the basic knowledge. It does not need to be studied too deeply. The general interview is not very demanding in this aspect. After all, it is not specialized in networking. In this regard, the effect of documents and videos is better, and the editor has also sorted it out. The method of obtaining is at the end of the article!
Linux
For Linux, if we want to master the basic use, we need to be very familiar with some common commands such as: directory switching commands, directory operation commands, file operation commands, commands to compress or decompress files, and so on.
Data Structures and Algorithms
If you want to enter a big factory, I recommend that you start to take a little time every day to learn algorithms and data structures after learning the basics of Java. In order to improve your programming ability, you can also stick to Leetcode. As far as interviews with major domestic and foreign companies are concerned, Leetcode can be said to have become a way to go.
database
I don’t need to say more about this knowledge, it’s very important, and I will!
- Mysql
- Redis
system design
Java development tools
Very important! Very important! Especially Git and Docker. Basic Git skills are necessary, try to host your code on Github during the learning process. Learn to use Docker to install software such as MySQL that you need to use in your studies, which is much more convenient and can save you a lot of time!
Java Interview Guide (Resume Guidance)
Summary
After mastering the above development tools, you can enter the framework of learning, and then expand your own technology stack , multithreading, distributed, microservices, JVM, Netty, etc. Later, you can contact the project appropriately. Doing the project is not only to do, but also Improve, improve. In addition, if your teacher has a related Java background project, you can also actively apply to participate. You must learn to allocate your time. There are a lot of things to learn, really a lot . It's enough to figure out which things are the focus and which ones are only enough to understand. Be sure not to spend your energy on learning various frameworks. Algorithms and data structures are really important! You can read the following Java core knowledge points to sort out the missing parts!

Write at the end
To be honest, as long as you choose to enter this industry, it means that you can't stop learning. At the current pace of technological updates, you will fall behind as long as you stop. Although we often laugh at ourselves and deliver food when we can’t do it, we can’t deny that we should actually develop to a higher level as an architect!
As the saying goes: programmers who don't want to be architects are not good programmers! If you also have the idea of an architect, then this set of Ali’s internal Java advanced collections will definitely help you! If you have a friend who needs this collection, just like the article, follow me and add a small assistant. Get it for free!
