This article introduces the relevant knowledge of "what are the ten minefields that must be avoided by Java". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Too much research and too little practice

The lack of practice in programming is fatal. If you start to learn from * days, you should practice programming every day. It's like learning boxing or dancing. If you learn it only through video, you'll never learn it. You will never have confidence in programming unless you make it a daily habit.

two。 Endless blind learning without goals

Some students, old as they are, simply like to study. They pursue the process, not the result. Even if it broadens your horizons, you have to admit that there is no point in wasting hundreds of hours (if not thousands) on trendy hobbies.

Programmers who only want to make money will not work for Google or other famous software companies, because the programming industry does not belong to them. Similarly, if you love programming, but don't want to spend time practicing every day, then maybe programming is not for you.

3. Learn too many skills at once

The field of software development is a deep sea of data and coding tools. If you expect to learn something that is hot and looks interesting, you may be completely confused at the beginning. This is why you need to make a specific plan based on your situation, including core coding projects and programming tools that incorporate Java. Specific plans and goals can also help you avoid becoming an endless learner and set your learning within a clear time frame.

4. Create a learning gap

Do you remember the motto of learning Java: "practice coding every day"? Well, whenever you want to skip a few days of coding study, think about this. If beginners fish for three days and sun up their nets for two days at the beginning, the consequences will be more serious than expected. Once you start to learn a new piece of knowledge, which involves previous knowledge, you will find that you don't remember what you learned before. This amazing amnesia will continue to hinder your progress, so try your best to learn and move forward without interruption.

5. Think that as long as you know Java, you can start coding.

A good developer must master the language as a necessary tool. Some people may think that programming must be good at math-no, not necessarily. Similarly, knowing how to write code doesn't mean you're going to be a programmer. Programming also requires many other skills: strong logical thinking, the ability to solve problems, and the ability to visualize the structure and sequence of the program. Experienced programmers will consider the logic of the solution before starting to write code.

6. Get caught up in a difficult theory

In general, the time spent on tasks or research is not directly related to the success of things. When learning Java, persevering attitude is the key to solving problems and learning new knowledge. But sometimes you need to skip the difficult problem first and then find the core of the problem later. Friendly advice: don't try to memorize the code, and don't get too obsessed with the "how it works" in the code. Many of Java's processes run automatically, so you can pay more attention to the intuitive feel of programming and keep making yourself more proficient.

7. Ignore the importance of readable code

When learning to program, the first task is to make the code work. This is why beginners do not pay attention to readable code with clear annotations, which may later be "decrypted".

But most experienced programmers would do such a thing. When they encounter some unfamiliar code, they try to understand what the code means and what the code is going to do. Only by working hard enough can you learn how to write readable code at the right time.

8. The code is not tested regularly.

It's a pity, but it's true that the code you write doesn't always work as scheduled. This requires regular testing, so don't let subsequent errors accumulate. In this way, only a small number of problems need to be dealt with at each stage, and there is no need for repeated and painstaking debugging to find out where the vulnerability is and when it occurred.

9. Learn Java alone

In view of the fact that there are many tools and resources online to help you learn successfully, people will often choose to teach themselves programming. But people will ignore the real learning communication. In fact, it will be more efficient to participate in as many study groups as possible. For example, Coderanch and Stack Overflow forums (both program-related IT technology Q & A sites) have many platforms for Java programmers to discuss. In addition, there is an Oracle Java community that encourages newcomers and experienced developers to join the Java forum and follow Oracle Java blog updates. It is worth mentioning that the Java community on Reddit has more than 107000 people.

10. Think that one day I will know all the coding knowledge.

As a programming rookie, listen to the advice of experienced colleagues and make unremitting efforts. The field of programming is changing with each passing day, which requires learners to always keep a learning attitude to master new knowledge and new technologies that keep pace with the times, so that they can become sought-after experts.

The secret of success in learning Java

Arrange your study time and minimize interference.

Rain or shine, daily coding.

If you can say it again, you might as well do it.

The right question. Join discussions in Stack Overflow and Coderanch forums, make virtual friends in programming courses, and work on complex projects together.

Programming visualization. Try to make a portfolio so that others have a chance to see your work.

Even if you succeed, keep on studying every day.

All in all, there are the broadest resources available today: Java blogs, guides, tutorials, project reports, courses, and coding "Battlefield". So now mix these "educational cocktails" in the right proportion and have a sip.

Several tools for learning Java

1. Resources for multiple coding languages:

CodeAcademy-- learn coding through coding

CodeAcademy has been a practical programming task since the beginning of the class. From simple to complex. Try to find your own solution when you encounter a problem. If you find it difficult, you can click the prompt on the taskbar for help, or go to the frequently asked questions (FAQ) for answers. CodeAcademy is a good complementary tool for learning Java. You can use it to improve your programming skills, but you also need other resources to learn key concepts.

Codewars-participate in the coding competition

Once you have mastered the basics, you can try Codewars to make yourself more confident in coding. This is an online platform where you can compete with other programmers and improve your coding skills in multiple programming languages. You can write solutions in a browser and check them step by step; you can write code individually, or you can team up to deal with tasks. The more tasks you solve, the more you get.

two。 Strictly used for learning and practice Java: CodeGym.cc

Interesting learning: CodeGym is an online learning platform that uses gamification to make your learning experience interesting. The course is divided into four tasks, setting storylines in the future world and unique character settings. Each task consists of ten levels. There are as many as 10-13 lessons at each level, plus dozens of practical tasks. As with CodeAcademy, students can write code through the Network Integrated Development Environment (web IDE), starting with the * class. Everything is simple: read the task, write the code, and then click the "check" button to get the result immediately. Unlike other coding exercises, it provides a clear explanation of Java theory, so it is very convenient for all beginners.
