I. Introduction
To be honest, when I participated in this skill tree evaluation, I mainly liked the prizes, but I was a little disappointed to hear that there would be no *3 prizes for people without the community. After all, I have uploaded more than 60 articles. Next, I will examine this from a user's point of view. I may be a little obsessive-compulsive, and I always like to add good things to my projects to achieve the ultimate.
I won't write the directory here, it's meaningless
2. Java Skill Tree Evaluation
1. It is best to set it as a separate link here, not all browsers can jump to right-click after selection.
2. Where is the one-click copy symbol? If the code is too long, for example, more than two or three pages, it is easy for users to copy the wrong lines, which will lead to a decrease in experience.
3. I am a bit open to these articles, but the number of pageviews does not increase after refreshing
4. Excuse me, how did you get this rating? I didn’t see it when I clicked it in. Where did the user rate the content of the article? How many rating levels are there? What are the rating standards? What should I do if I encounter a malicious rating blogger?
5. If the new box gives the correct answer and gives the analysis, I think it is quite good. If a person answers the question incorrectly, it proves that he will not. If he does not, it is useless to debug the code. , and the blue word in the middle says: Go to the notebook to debug the code
after opening: Service startup failed?
6. I don’t think there is any need to write 1234 here. If I write too much, it will look messy for readers. If this is the case, although it is not a serious mistake, the priority is still quite high. Besides, isn’t the font in front of it marked in blue? , why bother
7. There is a problem with the screenshots here
8. It’s still the picture in 7. It is strongly recommended not to add this kind of domain name or name. I like to add it when I write articles, because it can prove that I wrote it, but you don’t seem to use it very much, even if It can't affect the reader's view of the picture.
9. Many places where code is written are in different formats, it is recommended to unify
10. This picture seems to be written with ProcessOn. It is recommended not to bring this kind of grid behind it, it is not beautiful
11. For example, let's say the answer to this question is A. Don't you think there is something wrong here? 
After choosing A, if the answer is not right, I will choose B, and it is not right, then. . . . . . .
Are you kidding me? The words "None of the above" are dynamic. If we take the English test in the computer room, if you want to play like this, I will definitely give you a compliment.
12. When I saw this, I suddenly found that there seems to be no directory in front and there is no drop-down bar on the right. I don't know where I saw it, how can this work?
13. For such a long page, my suggestion is to add an arrow or sign at the bottom right that goes straight to the top. I forgot the name. Anyway, the function is to go straight to the top with one click. You don't use the pull-down bar I mentioned above on your right. Is it a little hard to turn up by the scroll wheel?
14. Are the first, second, third, and fourth cases written? Case 1 is in a for loop; case 2 is in a while loop. . . . . They belong to different loops, how can they link this case together? You can say: for loop case, while loop case, etc.
15. Would it be better if the ABCDE here is written as the first, second, third and fourth steps? I think it is best to write it in accordance with the readers’ reading habits. For example, the steps are as long as 30 steps. Do you want to create a few English letters by yourself?
16, the words come out, not beautiful
17. I don't know if all of your codes have been Formatted (Ctrl+Shift+F), but I think there must be any, it is best to check them all
18. I suddenly found that there is a green leaf here. Under what circumstances will this green leaf exist, and under what circumstances will it light up?
19. I don't know where you got the picture, but it's definitely not your own, it's too vague
20. Is there something wrong with this minus sign?
21. If possible, can you draw without hands?
22. Is there something wrong here? It is recommended to sort it out. There are many same mistakes below, which are very low-level. It is impossible to pass the screenshots on the complete set.
23. Here I strongly recommend a line break, because there are words behind, few people will think of the box in the middle, and there is something on the right
In fact, there are many more below, so I won't write them down here. The main problem is the format. If you check carefully, you will find that it is like going to a vending machine to buy water. If you find that there is a wrong word on it, you will Pay? I'm guessing you'll be worried that the water won't fall after paying.
3. Summary
The Java skill tree function is generally good, and it is worth recommending to use it in terms of experience, that is, the content, format, and font need to be optimized. The best reference article will explain that skill point. The redundant content can not expand our thinking, but will affect The efficiency of our learning on the skill tree; I hope that the CSDN skill tree will become better and better, giving readers the best experience.
I feel that this skill tree, no matter which one, it has a relatively comprehensive knowledge coverage. If it continues to develop in this way, its popularity may surpass that of the rookie tutorial. It is especially suitable for some beginners, including some people who are not so solid in basic learning. , From this point of view, it is quite awesome. After all, this is equivalent to publishing a book, but when it comes to this skill tree, is it for the purpose of teaching or to help others solve problems? This is to be clear, especially in terms of format. There are no big mistakes, but there are many small mistakes
