I'm here to give you some advice.
If you choose to train
Some people take you to training, but you need to quit your job and go to other cities, because the training institutions in big cities are definitely different from those in small cities, which means that not only the training cost is 20,000+,but also the accommodation for four months is at least 1 10,000, which is very expensive. But the advantage is that you have a learning direction, and someone will take you to learn, but the courses of training institutions are very urgent, and many of them are in a hurry. Whether they can keep up is still a question. Many people said that they didn't understand what they said before and began to talk about new knowledge. The more anxious they are, the less anxious they will be. Not everyone is suitable for fast training.
Training institutions will draw cakes for you to make your appetite big. Don't trust anyone to tell you what your salary is after you finish studying. It's inaccurate.
Remarks: If the training institution says "guaranteed employment", you can leave directly. No matter where you are, there can be no such thing as guaranteed employment.
If you choose to teach yourself
I basically get lost when I study by myself. I don't know what I'm learning, and then I can't read or write. I don't have an accurate and general learning direction. All I know is that I watch videos every day. This is a very common phenomenon. It's hard for you. If possible, finding a consultation place on the Internet will solve most of your problems. To learn Java, we must first find out what talents the enterprise needs now, what is popular now, and what we need to learn. How should I learn so as not to waste time? Where to find a job after studying, these are all questions you should think about when you start studying, especially how to study. I have met many people who study directly without thinking about anything, and the more they learn, the more confused they become. The reason is that they didn't think about learning Java at first. If you choose self-study, almost all the problems will be solved by yourself, which will be very difficult, but you have to believe that someone has succeeded in self-study. If you don't know much about this, you will still be in a helpless state.
Whether you are training or self-study, I will write some suggestions for you:
Suggestion 1: First of all, you should understand what kind of developers are needed by enterprises that recruit Java developers now, and what their minimum requirements are, because in the final analysis, they are all looking for jobs. If you don't know this, it is equivalent to learning without goals and not knowing what level to learn to be competent.
Suggestion 2: The learning method and learning efficiency of learning Java basically determine whether this person can persist in learning and why so many people give up halfway. It is because the more you learn, the more confused you are, and you don't know how to learn at all. It is easy to lose confidence and feel that you are not suitable. In fact, there is nothing suitable. Only when you learn will you feel that you are not suitable. You will feel fit when you learn. So it is very important for beginners to know this.
Today's market is different from five years ago. In five years, our industry is not only short of talents, but also short of novices. At that time, the company was willing to recruit interns and go to work in the company after training, but the salary would definitely not be high, so these people all jumped ship and the cost was too high. Many people have switched to java today, and the novices are full, but it is still difficult for the company to recruit someone with development experience, so you should not be the same as five years ago. Looking forward to several months of intensive training, there are still many companies that want you. Now the company wants people who can work directly and really master the technology, so it wants to dispel their ideas through intensive training.
When you don't know anything about the java industry, for example, you don't know the future development trend, what initial problems should be paid attention to when learning java, and you don't know the specific learning plan and learning route. I just buy books and watch videos blindly, and I have the idea of giving up in the medium term. This is mainly because I feel that the more I learn, the more confused I am, and I know if I can find a job if I continue studying like this. This is the biggest misunderstanding for beginners. I don't know how to learn Java, nor can I solve the problems in the process of learning Java. You can go to this Java learning skirt, which contains the latest learning routes and tutorials, and you can follow them. If you don't understand anything, you can ask questions in it at any time, and everyone will help you answer them. Here is this Java learning skirt, first a 494, then a 80 1, then a 93 1. Self-study for a period of time in this way, and then take part in the training after laying a solid foundation, so that there will be no situation that you can't keep up with the progress, and the foundation will be solid and you will learn quickly. At the same time, you can also study repeatedly where you can't, make sure that every knowledge point is thoroughly understood, and then start learning the next knowledge point, so that you won't be unable to find a job.
