Many years ago, I saw a 10-year-old primary school student develop a submission master software. Collect the mailboxes of different magazines and news departments to facilitate mass distribution.
Collecting various data is like looking for a job and researching which units are more promising. It is like choosing a university for the college entrance examination. It also requires a lot of comparison and screening.
When you usually use CHATGPT to ask questions, it shows your shortcomings. Record all the answers you get. This is the footprint of your growth. The answers inside are neatly formatted, not sloppy, and get it right in one step. Forums are a hundred times better than any search engine.
Technology is changing rapidly, and we have to accept it. Stand on the shoulders of giants and serve me!
For example, in the process of learning C# and Python, you should do questions, study grammar, and take notes. What code is input, what result is produced, record it yourself, and write down your learning experience. Isn't this just a lecture notes like a PPT?
Sometimes it is better than the teacher's tutorial because his level is too high and the students can't understand it, or many details are not in place. Collect the good articles you see and download good modules so that they can be referenced by different projects. With one change, all projects can be updated to the latest version simultaneously.
I have made some project templates for easy copying when needed. Some forms can also be made modular and have common settings. Multiple projects can be used directly by adding some parameters.
Good learning methods are half the battle. Learn programming happily, once your interest develops, you can slowly get started and after a long period of training, you can become a master.

The understanding of java compile once and run everywhere.
Java compile once and run everywhere means that a Java program only needs to be compiled once to run on different operating systems and hardware platforms. . This is an important feature of the Java language
and the key to Java becoming a cross-platform language.
Java's cross-platform nature is achieved through the Java Virtual Machine (JVM). JVM is a virtual computer that can run on different operating systems and hardware platforms. Java
programs are compiled into bytecodes when compiled, and these bytecodes can be interpreted and executed by the JVM.
Therefore, wherever there is a JVM, you can run Java programs.
The benefits of compiling Java once and running it everywhere are obvious. First, it can greatly simplify the developer's job. Developers only need to write one code and it can
run on different platforms. This can save a lot of time and energy and improve development efficiency.
Compiling Java once and running it everywhere can also reduce maintenance costs. Since Java programs can run on different platforms, there is no need to write different code for each platform. This
can reduce the amount of code and reduce maintenance costs.
Compiling Java once and running it everywhere can also improve the portability of the program. Since Java programs can run on different platforms, programs can be easily ported from one platform
to another. This makes the program more flexible and easier to adapt to different environments.
Compiling Java once and running it everywhere is an important feature of the Java language and the key to Java becoming a cross-platform language. It can greatly simplify developers' work, reduce
maintenance costs, and improve program portability. Therefore, compiling Java once and running it everywhere is an important advantage of the Java language and one of the reasons why Java is widely used in the field of software development
