precipitation 、 Share 、 grow up , Let yourself and others have something to gain !

One 、 Preface

1. First of all, congratulations on winning 3.8 Million downloads !

《 Relearning Java Design patterns 》PDF, My second ebook , So far, the number of downloads on the whole network 3.8 Ten thousand copies . This is a real-life scenario coding learning design patterns , The book deals with transactions 、 marketing 、 Place an order 、 seckill 、 Rule engine and middleware 22 A real scene , total 18 swastika 271 page , Time consuming 50 The liver is over ! Download instructions are provided at the end of the article

Of course, the promotion of this book needs the support of fans , I also thank my friend No. 1 to help reprint and share . There are also owners who use this book to make powder for themselves , Also thank you for your promotion of this book , So that more people can learn Useful design patterns .

2. You can move on with a good body !

10 month 4 Japan , Finally driving from the hospital 250 Km is back from Zhangjiakou ! It's really not easy to be in hospital , Fortunately, it's not a troublesome disease , It's just a small incision in the waist . Ha ha ha , Everything's OK , It's just that I haven't bathed for days , I didn't take off my clothes when I was sleeping . In the hospital, in addition to simple care , Basically, it's just idle . But I finally turned on the computer , It looks like this !

 Little brother Fu & The hospital attendants beat the code

3. by Java Face meridian and liver out of a Book PDF!

To make sure you understand is to really understand ! This is definitely not a simple book Interview manual , It's not simple Interview questions . It's an in-depth explanation of the interview scene Java Core knowledge , It's like learning to understand deeply :HashMap The perturbation function makes the hash more uniform 、ThreadLocal Use Fibonacci golden section to hash 、 The purpose of double ended queues is 、 Red and black tree 2-3 The relationship between trees 、 Shuffle algorithm and other core knowledge .

Two 、 brief introduction

Hello,world of java! Hello ,java The world of coding !

Welcome here , I'm glad you got the book . If you can stick to it and follow the practical examples in the book to learn , Then there must be a very profound harvest .

This is an introduction in the name of interview java Core knowledge of the book , A lot of knowledge is what you usually use , But a lot of details may have been overlooked . It's like ,HashMap The perturbation function makes the hash more uniform 、 In addition to this hash, there is ThreadLocal You can use Fibonacci golden section hash and so on , A series of knowledge points are explained to you in depth through practice in this book .

Let understand is really understand

Let understand is really understand , Is the core purpose of this book . For every knowledge point that needs deep understanding , From the most basic principles of analysis . And then through the examples that can be verified in practice , To learn these core knowledge points , Make the learning content simple , It can also go deeper .

1. Is it really just rocket building ?

It's often said that interviews make rockets , Screw in . But do you really have the ability to build rockets , Most of them are self mockery that they dare not admit their knowledge blind areas, technical bottlenecks and lack of experience .

During the interview

  • I hope you understand data structure , Because you're using HashMap、ArrayList、LinkedList, More handy .
  • I hope you understand hashing , Because then when you design the route , There will be a lot of choices ; division method Square hash Fibonacci (Fibonacci) Hashing etc. .
  • I hope you understand open source code , Because then when you have a problem , Can quickly locate , It is also possible to create middleware for system services , To better decouple the system .
  • I hope you understand design patterns , Because then you can write extensible 、 Easy to maintain program , Let the whole team develop in a better direction .

therefore , Never CRUD I chose you , It's not making screws to make you a tool maker . It's your technical ability that determines your vision , Vision determines the code you write !

2. Suits the crowd

  1. Have a certain programming foundation , Work 2 More than years of R & D personnel
  2. Hope to break through their own stage bottleneck period , There can be deeper technological growth
  3. Willing to be an architect , But we can't find a direction yet
  4. Interview for a job , I'm the worst one , Take the most expensive offer

3. What can I learn

  1. Study Java Commonly used API Data structure and algorithm of
  2. Learn more about perturbation functions 、 Load factor 、 Red and black trees 、 Fibonacci and other core knowledge points
  3. Break the learning bottleneck , Let's practice the way of learning , Add more knowledge to yourself

4. Reading suggestions

Little brother Fu , Series of special articles are inclined to practice , Each chapter has a corresponding case code for verification . So the best way to learn is to experiment with yourself , Only in this way can we learn the essence of the book more deeply . take care of every single thing personally , come on. !

3、 ... and 、PDF download

Before downloading , A little bit of support for the original author , give the thumbs-up Looking at Share Leaving a message. appreciate , You can get this book if you finish anything PDF Books .

Four 、 Close the tail

Let understand is really understand !

The most important thing to learn programming is not to memorize theory 、 Recite the result , It's not crazy to collect information and recite answers for interviews . None of this will make you gain a lot , It could be counterproductive . In case you recite it wrong , It's easy to tear it apart !

And for our coding line , If you don't want to be eliminated by this industry , You need to learn almost every day ! In particular, I feel that I have reached a certain bottleneck period , When it's hard to grow up again . When is the bottleneck period ? If you can't pass Ali's P7、 You can't pass Jingdong's T7 wait , Some high threshold positions in the Internet industry , Then it is in a technical bottleneck period .

time management ?, I don't think I have any time management , It's just that I haven't played a game in a year . I spend most of my time learning , Sort out the data 、 Writing an article 、 In terms of technical exchange . In particular, the materials are sorted out and compiled on the blog , I've made great progress in technology myself , At the same time, I have made great progress in writing . This is my biggest gain in nearly a year !

Last , This is not the end of the manual , And then it goes on ! precipitation 、 Share 、 grow up , Let yourself and others have something to gain !
