Is java good for self-study or training?

Now more and more people want to engage in java programming, and Java often relies on the practical skills they have learned outside of college education. At present, there are two main ways to learn JAVA language for the choice of learning methods of JAVA technology computer programming language: classroom learning in JAVA training class and self-learning Java language through video. However, they have their own advantages and disadvantages. Let's take a look at these two ways to learn the Java language: the advantage of attending the training class is that there are fewer detours, classes, learning environment and atmosphere, students' communication and teachers' guidance. This is a more reliable way of learning, and most people can graduate smoothly. However, attending classes often has some disadvantages. One is that there are many students and the period and class hours are relatively fixed. For some people with high learning efficiency, the progress may be a little slow, but for those with slow learning, it seems too fast to meet everyone's needs. At the same time, the charges are quite high. If you have an economic foundation, you can consider going. It is quite expensive. Generally, tens of thousands of tuition fees are needed. You will learn the basics for four or five months, and then continue to work with you on the project. It will be easy when you finish learning. If you choose the video mode, you can relatively reduce the memory pressure. Its advantage is that you should learn to develop your independent thinking ability through video learning, and you should have time to think. At the same time, you can watch it repeatedly and think about specific knowledge points. This learning method is similar to technical communication with people. However, the disadvantage lies in the lack of teachers' guidance and the inability to have a deeper understanding and grasp of unknown important knowledge points. In addition, after a period of study, I feel good about myself, but I do find myself ignorant in application or practical application. Another point is that the study time will be longer. The most important thing is not to be self-disciplined. If you learn, you will give up. Also, if you have the foundation of C language, C++ and c++, learning java well will be very simple. Everyone must have given it according to their own observations. All roads lead to Rome. As for self-study or training, it seems that both can be successful. The key is to see which one you are more suitable for.
