This may be the most comprehensive Java learning route

Hello everyone, I'm Dabin~

My undergraduate degree is not computer science. I started to learn Java by myself in my senior year, and got offers from several big companies in the Internet . I am quite experienced in learning Java. Let me share the Java self-study route I organized .

Here I also remind the younger students to determine their future direction as soon as possible, whether it is graduate school or work, and if they are looking for a job, they should also determine the job position as soon as possible. Those who want to change careers need to spend more time preparing. Many students only think about what they want to do in the future when they are about to graduate in their senior year. It is already a bit late at this time. If you miss the school recruitment and go to the social recruitment channel to find a job, the difficulty will increase by one level, and it will be too late to regret it!

Let me talk about my own experience (with self-study route).

contact programming

I basically never touched a computer before college, and I didn’t have a computer at home, and I never went to an Internet cafe. In computer courses in high school, I had to complete a self-introduction PPT for the final homework, and I didn’t know how to do it. In the end, I just copied the homework at the same table (I couldn’t copy and paste. I had to teach at the same table, covering my face).

One month after the college entrance examination, I bought a computer and started using it.

In the first semester of freshman year, the department opened a C language course, which was also my first contact with programming. The teaching materials are in English, and it is quite difficult to learn at the beginning. Every time I do a coursework, the students around me are copying and pasting, and so am I.

I remember that when I was talking about the chapter on pointers, I was confused. I was distracted for a while, and when I looked back, I no longer knew what I was talking about.

Later, there was an interest group in the department, because I was usually free and wanted to tinker with something, so I joined it. At the beginning, I didn’t understand anything. The teacher recommended me to learn about 51 single-chip microcomputer. I took a thick book about 51 single-chip microcomputer, followed the demo in the book, and discovered a new world! It turns out that programming is so interesting!

I remember when I ran out of the running water lamp for the first time, I was so excited and full of sense of accomplishment! Some motors, infrared remote control and other demos are also written later. Since then, my interest in learning programming has been sparked.

In the sophomore year, the counselor released the information of the National Electronic Design Competition in the group. The competition questions were related to the quadcopter. At that time, I was more interested in the quadcopter, so I invited two friends to participate together. There is only one month before the competition. During that month, I left early and returned late every day. While eating, I was still thinking about which piece of code had a bug. Although I failed to win the award in the end, I learned a lot of knowledge and improved my programming ability in the process.

decide to transcode

In a blink of an eye, the junior year started, and I began to struggle with whether to take the postgraduate entrance examination or work. After thinking about it for a week, I also entered the laboratory of the department to experience the life of a graduate student. In the end, I followed my inner thoughts and decided to find a job directly.

I consulted the employment situation of the brothers and sisters in this major in the past years, and most of them still found jobs in the Internet direction. A brother in a traditional industry also advised me to apply for a job in an Internet company, because there are a lot of overtime in traditional industries, but the wages are extremely low. . In the end, I decided to switch careers as a programmer and find a job related to the backend.

So which language to learn? There were three options at the time: c++, Java, python.

At that time, python was relatively popular, but after some careful consideration, I chose Java. Why choose Java?

Very simple, the market demand is large, and the learning difficulty is moderate. Compared with the classmates in the class, I lack the basic computer knowledge of the system, and I am less than a year away from the autumn recruitment, so I still choose Java, which is less difficult to learn.

self-study

After determining the direction, start to develop the learning route. I have to say that there are really many things to learn in Java. .

During the self-study period, I encountered a lot of problems, such as some environmental configuration problems, and sometimes I worked on it for several days, which greatly discouraged my enthusiasm. In the middle, I also doubted my level many times, whether it is not suitable for programming, and almost gave up. Fortunately, I persisted in the end.

For more than half a year, except for the usual classes, the rest of the time was in the library. On weekends or holidays, I wake up at 7 o'clock every day, go to the library to start studying at 8 o'clock in the evening, and return to the dormitory when the library closes at 10 o'clock in the evening. Every day, I am the last group to leave the library. Go back to the dormitory, take a shower, and continue to live until after twelve o'clock (the volume king!).

Many people are asking, is it too late for me to start learning Java by myself in my junior year? I think it depends on the individual's dedication and learning ability. Some people are better at self-learning, and can devote 10 hours or more to studying every day, and that's totally fine.

The self-study process is still very hard. To endure loneliness, the most important thing is to persevere!

Based on my self-study experience, I have sorted out some experience summed up by stepping on pits in the learning process. I hope that self-study friends can avoid detours:

• Pay attention to practice , don't just bury your head in reading, you must write more codes.
• When you first start self-study, you don't need to delve into the details too much, otherwise you may doubt your learning ability. When you have a certain foundation later, and you look back and review it, you may suddenly realize that it is not as difficult as you thought at the beginning.
• You can add some communication groups appropriately, and communicate with other people when you encounter knowledge points that you don’t understand.

Well, let me share with you my self-study experience.

self-study route

First look at the Java learning roadmap:

• springboot: habit is better than configuration, automatic configuration. At present, many companies use Spring Boot internally.
• springmvc: A lightweight web framework based on the MVC architectural pattern
• Mybatis: orm framework.
• springcloud

Spring

Most companies will use the Spring framework, must learn! . Mainly understand Spring's aspect-oriented and dependency injection features, and learn to use Spring to build applications. The recommended book "Spring in Action" will take you step by step to build a Spring application through a demo

The video recommends the latest version of the Spring5 framework tutorial by Teacher Wang Ze from Shang Silicon Valley. The video has just been released, and the content is also advancing with the times. It is worth learning!

SpringMVC

SpringMVC is a lightweight web framework based on the MVC architecture pattern . For beginners, it is necessary to master the process of web request from sending to corresponding, what SpringMVC does, and the idea of ​​MVC pattern.

The video recommends the latest SpringMVC tutorial for Java from Crazy God.

[Crazy God Talks Java] The latest SpringMVC tutorial IDEA version is easy to understand.

My shoe

MyBatis is an excellent persistence layer framework. MyBatis helps us do many things: establish connections, operate Statment, ResultSet, handle JDBC-related exceptions, etc., which simplifies the development process. Recommended book "Mybatis in simple terms".

The video recommends the latest and complete Mybatis tutorial of Kuangshenshuo, which has the most views on station b and has won unanimous praise from many friends.

SpringBoot

After learning SSM, you have to learn SpringBoot further. I believe that many people will have a headache when faced with various configurations after learning Spring. The emergence of SpringBoot solves this problem. SpringBoot removes a large number of XML configuration files and simplifies complex dependency management. The book recommends "Spring Boot in Action".

The video recommends the latest SpringBoot2 authoritative tutorial of the 2021 version of Raytheon of Silicon Valley.

SpringCloud

Now interviews will basically ask about microservice-related content, it is best to understand the knowledge related to microservices. Service registration and discovery, load balancing, service degradation, API gateway, etc. Recommended book "spring cloud microservice combat"

For the video tutorial, you can take a look at the SpringCloud tutorial by Mr. Zhou Yang from Shang Silicon Valley~

concurrency

What is concurrent programming, in simple terms, is to make full use of the cpu, execute multiple tasks at the same time, and complete tasks quickly.

For related content of concurrent programming, you can read the book "JAVA Concurrent Programming in Practice".

Video recommendation Crazy God speaks Java, very good video.

The main knowledge points are:

• The concept and case of thread
• Principle of thread pool
• Inter-thread communication method
• 锁（synchronized、ReentrantLock）
• Concurrency tools (CountDownLatch/CyclicBarrier/Semaphore)
• atomic class
• AQS
• Thread life cycle state
• Java memory model

Redis

[External link picture transfer failed, the source site may have an anti-leeching mechanism, it is recommended to save the picture and upload it directly (img-j1Reh2cA-1684976576806)(http://img.topjavaer.cn/image/Redis knowledge points.jpg)]

It is used to cache hot data to speed up reading and writing, thereby improving performance. Now Java backend interviews basically ask Redis.

Books recommend "redis combat" and "redis design and implementation".

Video recommendation Kuangshen said that the latest ultra-detailed tutorial of Java's Redis not only teaches you to learn Redis, but also teaches you how to learn.

message queue

Message queue is a data structure in the basic data structure FIFO. It is used to solve problems such as application decoupling, asynchronous messages, and traffic cutting. It can achieve high performance, high availability, scalability, and eventual consistency.

The video recommends Dark Horse's RocketMQ tutorial and Baizhi Education's RabbitMQ tutorial, just choose one of the two to learn!

JVM

[External link picture transfer failed, the source site may have an anti-theft link mechanism, it is recommended to save the picture and upload it directly (img-S2cTXZjt-1684976576806)(http://img.topjavaer.cn/image/JVM Knowledge Point Summary.jpg) ]

JVM is also what is often asked in interviews. Java developers don’t need to do memory management and garbage collection by themselves, the JVM does it for us, but it is still necessary to understand the working principle of the JVM, so that when problems such as oom occur, they have ideas to troubleshoot and solve problems. The book recommends Mr. Zhou's "In-depth Understanding of Java Virtual Machine".

The video recommends Song Hongkang's full set of courses in Silicon Valley. The full set of courses is divided into three chapters: "Memory and Garbage Collection", "Bytecode and Class Loading" and "Performance Monitoring and Tuning".

Basic knowledge of JVM:

• jvm memory structure (program counter, virtual machine stack, local method stack, heap, method area, runtime constant pool, direct memory)
• class loading process
• parent delegation
• garbage collection algorithm
• garbage collector
• Tuning tools (jsp/jstack/jstat/jmap, just understand)

Computer Basics

To learn programming, you must lay a solid computer foundation!

For non-major students, the biggest gap between them and the students of major classes lies in basic theoretical knowledge . If you are a non-major self-taught programmer and want to enter a large factory, then the basic computer knowledge must not be left behind.

Every qualified programmer should know the structure of the computer system, what the internal logic is, and have his own thinking.

In short, basic skills are very important!

operating system

No matter what programming language you learn, you need to deal with the operating system. If you are not familiar with the operating system, you will encounter many obstacles in your future learning, such as thread process scheduling, memory allocation, Java virtual machine and other knowledge, and you will be at a loss. Therefore, only by understanding the operating system can we better learn other computer knowledge.

book recommendation

Entry-level books: "Modern Operating Systems", "Introduction to Operating Systems" , Advanced: "In-depth Understanding of Computer Systems"

Strongly recommend the book "In-depth Understanding of Computer Systems".

CSAPP is a very good book, which combines the basic knowledge of computer composition principles, operating systems, network programming, parallel programming principles and other courses. For those who are new to programming, or those who are not from majors like Dabin, this is a guiding book. It will tell you, if you want to become an excellent programmer, you should focus on understanding the underlying principles of computers, Tell you which courses you should focus on in the future self-study process, such as operating system and architecture.

Why study Data Structures and Algorithms? For students majoring in computer science, this course is compulsory, and the postgraduate entrance examination is basically a compulsory subject. For programmers, data structures and algorithms are also very important points of investigation necessary for interviews and written tests.

Data structures and algorithms are one of the important criteria for programmers to embody internal skills, and data structures are also used in various aspects. The data structure also contains some object-oriented ideas, so learning to master the data structure will greatly improve the abstraction ability of logical thinking.

book recommendation

"Big Talk Data Structure" and "Algorithm Diagram"

The biggest feature of this book "Big Talk Data Structure" is that the whole article is described in an interesting way, and a variety of life knowledge is quoted for analogy, and the graphic language is fully used to reflect the abstract content. Some classic algorithms involved can be analyzed line by line and compared with multiple algorithms. This book is especially suitable for beginners.

"Illustrated Algorithm" is a very good introductory algorithm book, with rich examples, rich pictures and texts, and explains the algorithm in an easy-to-understand way, aiming to help programmers better utilize the energy of the algorithm in daily projects.

Many students who learn Java may ask if there is a Java version of data structure and algorithm books?

Of course there are, you can read the book **"Data Structure and Algorithm Analysis Java Language Description"**, and describe various data structures and algorithms in Java language, which is easier for Java developers to understand.

video recommendation

UCSanDiego's data structure and algorithm special course : https://www.coursera.org/specializations/algorithms

The data structure course of Grandma Chen Yue of Zhejiang University .

Grandma Chen Yue and Professor He Qinming of Zhejiang University jointly taught a very classic course. Grandma my idol!

Data structures and algorithms mainly study the following contents:

• Basic data structures (arrays, linked lists, stacks, queues, etc.)
• Tree (binary tree, avl tree, b-tree, red-black tree, etc.)
• heap structure
• Sorting algorithms (bubble sort, selection sort, insertion sort, quick sort, merge sort, heap sort, etc. and time and space complexity)
• Dynamic programming, backtracking, greedy algorithm (swipe leetcode more)
• recursion
• bit operation

Still feeling exhausted after learning? It can be consolidated with the help of some question brushing websites. Below are a few recommended websites for brushing questions.

Niuke.com

As a popular celebrity in Niuke, let's give a wave of publicity to Niuke! (Niu Ke pays money!)

Niuke.com has a super-rich IT question bank, question bank + interview + learning + job hunting + discussion, basically covering all written interview questions, and can be called an "Internet job hunting artifact". Here you can not only brush up questions, but also discuss and communicate with other cattle friends to grow together. There are also various referral opportunities on Niuke, which is also very good for students who are looking for jobs.

LeetCode

Force button, force push ! Li Kou abused me thousands of times, and I treated Li Kou like first love!

From now on, you will be able to thank me for a few months’ worth of algorithmic questions every day (tsundere face)

When I first started doing algorithm questions, I chose to do it on Likou. When I first brushed the easy-level questions, I felt a bit difficult. After half a year, I didn't panic when I encountered medium-level or even hard-level questions.

But practice makes perfect.

LintCode

A quiz site similar to Leetcode.

LeetCode/LintCode have about the same amount of questions. LeetCode's test case is relatively complete , and LeetCode has a discussion area , it is more meaningful to look at other people's code.

LintCode's UI, tagging, and filter are more flexible and have more advantages. You can choose one of them to brush the questions.

database

Internet applications are mostly data-intensive applications. For real-world data-intensive applications, unless you are going to start from the wheel of basic components, there are not so many opportunities to play with fancy data structures and algorithms.

In actual production, the data table is the data structure, and the index and query are the algorithms. The application code often plays the role of glue, handling IO and business logic, and most of the other work is to move data between data systems. In the broadest sense, where there is state, there is a database. It is everywhere, behind the website, inside the application, stand-alone software, in the blockchain, and even in the web browser farthest from the database.

book recommendation

• "MySQL Must Know"
• "High performance mysql"

"MySQL Must Know" is mainly about the basic syntax of Mysql, which is easy to understand. After you have a foundation, read "High Performance MySQL".

• Reasonable use of design patterns and documentation of the use of design patterns will help others understand the system faster
• Learning design patterns will help beginners understand object-oriented ideas more deeply

Classification of Design Patterns :

1.1 Creational patterns

The creation pattern (Creational Pattern) abstracts the instantiation process of the class, and can separate the creation and use of objects in the module.

Creational patterns include factory method patterns, abstract factory patterns, singleton patterns, builder patterns, and prototype patterns

1.2 Structural patterns

Structural Pattern describes how to combine classes or objects to form a larger structure, just like building blocks, which can form complex and more powerful structures through the combination of simple building blocks.

Structural patterns include adapter pattern, decoration pattern, proxy pattern, appearance pattern, bridge pattern, combination pattern, flyweight pattern

1.3 Behavioral patterns

A Behavioral Pattern is an abstraction of the division of responsibilities and algorithms between different objects. Behavioral patterns focus not only on the structure of classes and objects, but also on their interactions.

Behavioral patterns include strategy pattern, template pattern, observer pattern, iterative sub-pattern, chain of responsibility pattern, command pattern, memo pattern, state pattern, visitor pattern, intermediary pattern, interpreter pattern, etc.
