How to get started with java beginners

Many people are confused about which one to start learning JAVA. The following are my four learning routes and directions. I hope it helps you!

(1) Learning the basics of language Obviously, mastering the basics of language is the first step. If you don't know the basics, then you don't know if you did something wrong or what to do next. Of course, this does not require you to remember all the basic knowledge, such as all Java keywords, core concepts or basic coding techniques.

2 Start writing some small programs If you are sure that you are familiar with most of the basic knowledge and concepts and can relate them in some way, you can proceed to the next step. You can start to try to write some very basic Java programs, such as printing hello world, realizing simple addition and subtraction, and so on.

(3) Using Java API to write advanced programs When you have completed most of the basic programming and mastered the basic programming skills, you can proceed to the next step. I advise you to study the Java collection and the API in Java IO. You need to be familiar with the various classes and interfaces provided by these APIs and use them to create programs. It should be noted that you should look for existing APIs and methods to implement functions, rather than implementing these logics yourself. Your task is to be familiar with these APIs, so you can only find solutions in these existing APIs.

(4) Writing Desktop Programs and Web Applications Through this step of learning, you can be confident in any Java interview and when discussing Java-related topics. You need to write at least one Java desktop or GUI application, such as calculator, and then write a Web application, such as hospital management program. In the previous study, you have mastered the most basic Java knowledge. Now you need to explore and then write these two applications.

Most importantly, it can help you form a good habit of completing a task at all costs. This persistent attitude is very important for the long-term development of your career.

Finally, the most important thing is to watch more video tutorials. There is a lot of such information, so you can search it yourself. There are a lot of learning materials about java. I take the liberty of recommending one for your reference: a web link.
