What foundation is needed to learn java?

With the widespread use of Java as a language, more and more developers are beginning to learn this course. So, what foundation is needed to learn Java? What knowledge should I get into when I’m just getting started with Java? What should you learn to get started with Java?

First of all, I want to explain that JAVA has three major directions (J2se, J2me, J2ee). The techniques you may learn and the time you may spend in different directions may be different. different. I work in the web direction (J2ee). Apart from some simple C language syntax, I don’t have much programming foundation when learning Java. I used to think that programming requires a strong foundation in mathematics and English. Now it seems that this is not the case. It is not necessary. As long as you have certain logical thinking ability and master some common computer vocabulary, you also need to have certain self-learning ability, because software development requires continuous learning.

Secondly, I would like to talk about my learning process. I downloaded the JAVA teaching video from the Internet, watched the basics of Java from beginning to end, basically typed the above code, and then I I read the basic Java book once, and it took about a month to complete the book including the exercises above. At this time, you should have a relatively full understanding of Java syntax and basic knowledge.

Then, do some small projects and follow the steps in the video. It is best to be able to write independently and write as much as you can. Generally, it is difficult to find relatively new free project libraries on the Internet, because the project library needs to be updated in real time to ensure that it meets the needs of the market, and its upgrades and updates require money, so go to a training center to take advantage of its powerful projects. The library is a good choice for practical operations.

After operating for a period of time, you have a certain feeling about Java, and you need to start choosing your development direction. I chose J2ee. If you also want to take this path, you can continue to watch videos about J2ee, first html Js css, then Jsp serverlet, and then look at struts spring hibernate and other frameworks. At the same time, you can watch videos about design patterns from some large training institutions, preferably those recorded by IT experts. Of course, you also need to learn databases. With the accumulated experience in project work, you can almost go out to work in half a year.

I don’t know much about you if you go in other directions. Let me talk about my personal opinion. The prospects of J2me and J2se are not as good as J2ee. However, I have colleagues who are engaged in Android platform development. This does not require J2ee knowledge. You can buy an Android version and take a look. This direction seems to be very promising. , you should have often heard about mobile phones based on the Android platform. If you go in this direction, you can learn some Linux knowledge and C knowledge, because these are the bottom layers of this platform, and this is not necessary.

Having said so much, I hope it can be helpful to everyone. Finally, I would like to say that the most important thing to learn something is to do it. Only by doing it can you deeply understand and remember it firmly.
