Java programming language is an object-oriented programming language that can write cross-platform application software.
Java programming technology has excellent versatility, efficiency, platform portability and security, and is widely used in personal PCs, data centers, game consoles, scientific supercomputers, mobile phones and the Internet. It also has the world's largest developer professional society group. In the global cloud computing and mobile Internet industry environment, Java has significant advantages and broad prospects.
For novices who want to learn by themselves, before learning, here are some suggestions for you!
1. Find a good textbook
Good teaching materials can let you enter the world of Java faster and better. For students in school, your textbooks are usually good, and you can choose suitable textbooks online or in bookstores.
Two, learn basic grammar
To learn Java, to put it plainly, is to learn its grammar, function, structure, etc. Then write the code according to its syntax. Java syntax is the foundation of learning. When you start learning, it may be a little difficult to understand. It doesn't matter, this is normal. See more, ask more, practice more, and slowly you will get started.
Three, more hands-on practice
Learning Java is the same as learning mathematics. After learning the theory, you must practice it. Learning Java cannot be a free rider. Sometimes, the grammar and examples are simple and easy to understand, but when you write by yourself, it feels different. Only multi-hands programming, even simple small programs, repeating the simple examples in the book, is also accumulating and improving. Hands-on coding is inseparable from the support of programming tools.
Fourth, standard programming
As the saying goes, there is no square without rules. Programming is a process of turning thinking logic into code and letting the computer execute it. Special requirements are required. Whether it is variable, function naming or code format, consistent specifications are required. This makes it easy to read and modify the code. The standardization of the code occupies an important proportion in the quality of the code.
V. Notes
The role of code comments is not an exaggeration, just like a sign for tourist attractions. When we are programming, we are very clear about our own ideas. But after a while, or let someone else read the code. If the comments are abundant, reading the code can generally be replaced by reading the comments.
Note that the comments should be comments on sentences, process methods, or structures that have a certain degree of difficulty. Comments are not necessary if they are very simple and understandable. Get in the habit of commenting difficult code.
For beginners who are just learning Java, many people who are suitable will feel that they have no direction to learn, and the more they learn, the more confused they are. In this case, the learning method is generally wrong at the beginning. There is no professional and systematic study of Java technology. From the perspective of employment and saving time, if anyone encounters problems in this area, they can join my learning skirt 766.328.863. There are corresponding learning materials in them, and they can download them by themselves (suitable for beginners) and communicate with everyone. , Don't learn blindly by yourself, less detours is the biggest shortcut to learning Java.
Six, look at other people's code more
There can be many encoding methods for the realization of the same function. Read more of other people's codes, and use them to open up ideas and improve coding flexibility. You can even often get inspiration from other people's code, generate inspiration, and create excellent code.
Seven, the code is as simple and easy to understand as possible
The simplicity and correctness of the code are the most important. Don't write obscure code in pursuit of high efficiency. When you read and modify the code later, you will pay a lot for the obscure code. Remember, try to write the code in a way that beginners can understand, then your code will be very beautiful.
8. Master several commonly used design patterns
The design pattern is a summary of some programming methods summarized by the masters. Very useful. Learning design patterns can improve our programming flexibility and design rationality. Not only Java, but other programming languages, such as C# and C++, design patterns are also popular. Therefore, you have no reason to miss the programming essence summarized by the masters.
9. Learn more and communicate more
This is very helpful for improving your Java. Personal wisdom is limited. If you gather the programming experience of many masters, then your master journey will go smoothly.
10. Persistence is the magic weapon to win
Learning Java is easy to get started, but difficult to master. Never reduce your interest in it because you are afraid of difficulties. Many people are learning Java every year because it is so powerful. If you can persevere, then you are also strong.
If you still think that self-study is a difficult thing, it takes a lot of your energy, and you urgently need to find a more easy and efficient learning method, then it is recommended to find a professional to guide you, so as to avoid you from making detours. .
