Preparing for summer internship , In the process of preparing the autumn move , Many recording friends are confused about , I don't know what to learn , I don't know how to learn , It's like everything , It seems that nothing .

So there is no sense of direction in learning every day .

It's time to look at other people's learning experiences , War preparation experience is the most helpful .

This recording friend （ Planet nickname ：color） When graduate students enter the University, they decide to transcode , Start with zero Basics java, Summer internship to get bytes offer.

There are still many detours in the process , I also understand a lot of learning methods .

His experience is worth learning from , I believe after reading , Everyone will be impressed by their learning progress , planning Will have a relatively clear understanding .

Here's what he shared in Knowledge of the planet Inside Java The road to self-study ：

---

I wrote before , ByteDance summer internship , Back end development experience .

This time I will write another article on my self-study JAVA The way , I hope I can help you .

Background introduction

Undergraduate double non ,211 Master , Not a regular , No internship , No game , I taught myself almost all the way , Without the guidance of senior brothers and sisters , I don't have any friends to study with .

I am a 2020 year 9 Admission in May , So I followed the principle of "research and development" , second year graduated school student , In this order .

Grind on

The corresponding time point is almost 2020 year 9 month -2021 year 1 month .

At first, I decided to change my career , It is because the research group is engaged in theory , It's not easy to find a job , So I decided to switch to self-taught programming . In fact, at the beginning, I was very repellent to learn programming , When I was an undergraduate , I learned one C Language , But I almost forgot .

So it is zero foundation to start self-study , At the beginning, typing is a Zen , Now, there is no pressure on the two hands , So it's just by making progress every day , Learn a little every day , To this day .

in general , In the process of learning programming , I have been encountering difficulties , find a way out of a difficulty , But never give up .

Java Basics ：

About Java The basic part , I am looking at the power node , Old Du's video , His video is very interesting , Be my first teacher .

however , Just like everyone else , Forget after reading .

So I suggest you , It's best to summarize your notes , Easy to review .

For the question of forgetting after reading , Forget to read again , There seems to be no good way .

database ：

Here is also the video , Watching older videos , such as JDBC these , Now it seems , It's a detour .

I've also read a story about MySQL In the video , Then there's the code , You can follow the practice , Improve writing SQL Ability .

web front end , Back end ：

Here I learned HTML,CSS,JavaScript, These interviews are almost impossible to ask , And I forgot all about it . So I took another detour .

I also learned Servlet,JSP, These old technologies , They are all detours .

in general , Although I spent a lot of time studying , But we have taken quite a number of detours . It is recommended that you refer to what Kago shared on the planet Java Learning route . The above is just to complete the timeline , I don't recommend that you learn the old knowledge .

Study one winter vacation

I did a during the winter vacation CRM project ( Customer relationship management system ), For this reason, I learned AJAX,JQuery, A dynamic proxy ( It is not recommended that you learn ).

This project , The technology used is also very old , I didn't write it on my resume , Because I have forgotten all , Write it up , Is to pit yourself , ha-ha .

however , Finish the project , There's something to gain , such as debug The ability of , All these are helpful to the project of Niuke community .

Have a general understanding of how to develop a project , The presentation layer , The business layer , Persistence layer ,web This is how the project is basically played .

summary ： Grind on , Took a lot of detours , So pay attention to ： Choice is important , Direction is important , Choice is greater than effort , Go and have a look at the facial scriptures .

Grind it

Time ：2021-3 Month to 8 month ( I didn't go home during the summer vacation )

SSM frame ：

Mainly watching videos , Then in class demo Follow the knock .

The time spent in this part , Maybe at least one month .

But in fact, the framework is not very important , Computer foundation is important .( Byte's interviewer told me so , He said , It doesn't matter what framework your project uses , It mainly depends on your foundation .)

Personally, I think , Will use it , There is no need to understand the source code .

Data structures and algorithms ：

Here I learned the data structure and algorithm class of hanshunping , It took almost a month , But the gains are very small .( I don't suggest you watch it )

So I suggest you , Learn algorithms , Still follow Kago （programmercarl.com）,YYDS, No doubt. , Do it twoorthree times , During the interview , The algorithm is certainly not a problem .

Redis：

I learned some basic operations from the video , Forget when you have finished learning .

Redis Let's take a look at this piece of advice 《Redis Design and implementation 》

SpringBoot：

springboot I also watched a lot of videos on this one , Now it seems , It is also a detour .

Or that sentence , Will use it , Before the interview, there were eight shares , Just OK 了 , such as spring Of IOC,AOP these .

=============================================

Draw a dividing line , These above , Many of them don't have to learn , Or say , My learning method is very problematic , In limine , I thought that after watching the video , Knowledge will , You can find a job . Now it seems , It is self deception , Always stay in your comfort zone .

Now think about it. , Why didn't you meet Kako earlier .

After meeting Kako , I taught myself the way of programming , It seems that it is really beginning .

Yan ershang

Time ：2021 year 8 month -2022 year 1 month

I spent more time on scientific research this semester ( Mainly engaged in small papers ), I don't have much time to learn programming .

Time not mentioned below , They are basically doing small papers , Simulation , drawing , Write a paper .

Random code recording ：

From August , I started to brush questions , The first question brushing process was really painful , Even more painful than the time when I was preparing for the postgraduate entrance examination , It's really painful , occasionally , One afternoon , Even did a data structure algorithm problem .

But now that you have chosen this path , You can only go on with it , I can only force myself to do , Gnawing one question at a time , Finally 10 month 2 Number , Jot down the code （programmercarl.com） The above topic has been brushed once , Also thanks carl Brother's summary , It helped me a lot .

Next October 、 November , I spent a little time watching Xiao Lin's 《 Graphic operating system 》 I also saw 《 Graphic network 》( Not finished ).

From November to February , We are also doing the second brush of code random recording ( Because there are so many things , So the battle line is long ).

Brother Lin is also very awesome , Recommend his website ：https://xiaolincoding.com/

Yan Erxia

Time ： from 2022 year 1 month -3 At the beginning of .

During this period , It is mainly that I have read xiaolingo's graphic operating system and graphic network .

Then I reviewed MySQL Eight shares of , Put together a copy of MySQL Face meridian of .

Then review JAVA Eight shares of , Including the foundation , Assemble these .

In the last period of time, I also did the project of Niuke community , Because if there is no project , I really can't write a resume .( This project is on the knowledge planet , Kago's java Learning route ).

Then there is the written test , interview , Recite the eight strands .

At the end

Can get byte internship offer, I feel lucky , At the same time, I am also very scared .

I also failed in many written examinations , That's enough to say , Own or dish , There is still much room for improvement in the algorithm .

So I always have the mentality of learning from others , Keep up with the big guys , I also want to thank you very much @PrinceH23, It seems that he is the first one on the knowledge planet to get bytes offer Of .

meanwhile , It is also the kage , Brother Xiao Lin These big guys , I'm not a Cobain , There's a chance , Put your strength in the right place , Thank them ！！

In this paper, the PrinceH23, It should be regarded as the first recording friend to get byte summer internship on the planet this year , I got it in February , Then I shared a wave of experience on the planet .

After that, many recording friends went to him to communicate ,

Of course The author of this article color, One of them went to find PrinceH23 Recording friends for communication （ although PrinceH23 yes C++ The direction of the , But review strategies can be used for reference ）.

The original post of this article is also very popular on the planet , This is the comment area of this post ：

Can be in Knowledge of the planet 「 The essence of 」 Find the original post in ：

Finally, you are welcome to join the code Capriccio Knowledge of the planet , There are many excellent people here , There are many wonderful things ！

Many recording friends not only have good academic qualifications , Very hard ：

Sometimes what you need is a positive learning atmosphere , Let's see how this recording friend feels
