typical example

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

Step 1: Create a project, importMaven Dependencies

Step 2: Download the source code of tess4j and copy the tessdata folder into the project.

tessdata devolved language libraries, the default English library, Chinese library need to be downloaded separately, download address: /tesseract-ocr/tessdata/blob/master/chi_sim.traineddata.

The directory holds the images to be recognized.

Step 3: Test the code

/**

java image recognition

public class Test4JDemo {

public static void main(String[] args) throws TesseractException {

// If you do not put tessdata in the root directory you need to specify an absolute path.

String path = “E:/Workspaces/Module/Tess4JDemo/”;

ITesseract instance = new Tesseract();

//Set the location of the training library

(path + “tessdata”);

// If you need to recognize languages other than English, you need to specify the recognized languages and put the corresponding language packs into the project.

Self-introduction, I graduated from Shanghai Jiaotong University in 13 years, once stayed in a small company, but also went to Huawei, OPPO and other large factories, 18 years into Ali has been to the present.

Knowing that most Java engineers, want to improve their skills, often their own growth or enrollment classes, but for the training institutions moving thousands of tuition, really a lot of pressure. Their own unsystematic self-study effect is inefficient and long, and it is very easy to run into the ceiling technology stagnation!

Therefore, the collection of a "2024 Java development of a full set of learning materials", the original intention is also very simple, is that we hope to be able to help to want to self-study to improve and do not know where to start learning friends, while reducing the burden of everyone.

There are both zero-basic material suitable for white people to learn, but also suitable for more than 3 years of experience partners in-depth learning to enhance the advanced courses, basically covering more than 95% of the Java development knowledge points, the real systematic!

Because the file is relatively large, here is just part of the directory outline screenshot out, each node contains a large factory interviews, study notes, source code handouts, real-world projects, explain the video, and the follow-up will continue to update!

If you find this content helpful, you can add V to get: vip1024b (note Java)

At the beginning of sharing with you I said, I was not prepared for the interview, all rely on the usual accumulation, indeed a little bit of ad hoc, so that I am still quite chagrined. (I could have gotten 40k if I was prepared, but only 30k+ if I wasn't. Do you know what that feels like?)

How do I prepare for an interview?

1. Pre-preparation (technical deposition)

Programmer interview is actually for the technology of a final exam, your technology bully, then you are the master. Big factory for the technical requirements are mainly reflected in: basic, principle, in-depth study of the source code, breadth, five aspects of the actual combat, and only the principle of theory combined with the actual combat in order to eat through the technical points.

Here are some notes on the material I'll be looking at to help you learn Java from the ground up, from point to point, and deal with the soul-searching questions of interviewers at the big firms

This part of the content is too much, I only posted part of the content to show you, forgive me!

Java programmers must see "Java Development Core Notes (Huashan Edition)

Redis Learning Notes

Java Concurrent Programming Study Notes

Four parts, breaking down concurrent programming in detail - Concurrent Programming + Patterns + Applications + Principles

Java programmer must read book "deeper understanding ava virtual machine 3rd edition" (pdf)

Big Factory Interview Essential Questions - Data Structures and Algorithms Pooled Notes

Others like Spring, SpringBoot.SpringCloudSpringCloudAlibaba, Dubbo, Zookeeper, Kafka, RocketMQ, RabbitMQ, Netty, MySQL, Docker, K8s, etc. I've organized them all, so I won't show them all here.

2. Brush up on interview questions

① Big Factory HF 45 written questions (IQ questions)

② Summary of interviews at BAT's big factories (some screenshots)

③Interview summary

3、Combined with the actual, modify the resume

Programmer's resume must be more effort, especially on some of the words to deliberate again and again, such as "proficient, familiar, understand" the difference between the three must be distinguished clearly, otherwise it is digging a pit for themselves. Of course not packing, I can give you my resume for reference, if not enough, then the following resume templates for you to choose:

Shared above, I hope you can find a good job in the golden three silver four job-hopping season, but also remember that the technology must be usually work kind of cumulative or self-study (or enroll in a class to follow the teacher to learn) through the actual combat cumulative, don't make a hasty retreat.

In addition, the interview will not meet the question may try to speak their own thinking, because some questions are not to examine our programming ability, but logical thinking expression ability; Finally, usually to self-analysis and evaluation, good career planning, and continue to feel, improve their programming ability and abstract thinking ability.

A person can go very fast, but a group of people can go farther. Whether you are engaged in the IT industry old bird or newcomers interested in the IT industry, are welcome to sweep the code to join our circle (technical exchanges, learning resources, workplace trolling, large factories push, interview coaching), let us learn and grow together!

I analyze and evaluate, plan my career well, and keep figuring out how to improve my programming and abstract thinking skills.
