Self taught programming can understand the code, but what if you can't write it yourself

First , Self taught programming is feasible , Many students have entered the Internet field through self-study programming , But in the process of self-taught programming , Often take some detours , Indeed, many students have been unable to form their own programming ideas for a long time , And finally gave up to continue learning .

The most common problem with self-taught programming is that you can understand the code , But I can't write it , There are three reasons ：

One is that you don't master the basic programming process .

Programming flow is the basic step of a programming language in solving a logic problem , such as Java The basic programming flow of is the definition of classes 、 Object creation and method invocation .

After mastering this basic programming process , It is necessary to abstract according to the specific business logic , Finally, the modular packaging , This process also involves algorithms 、 The level of abstraction , And modular tools and methods .

The second is that they have not mastered the basic programming mode .

Mastering the programming process is the first step , Then you should master some classic programming patterns , This will largely guarantee the quality of your code .

Especially for junior programmers who are just beginning to program , Try to use mature programming patterns , This is of positive significance for reuse and debugging .

The third is the lack of practical experience in scenario development .

Learning a programming language usually goes through three stages , One is the study of basic grammar , The second is to accumulate knowledge around the main direction , The third is to practice scenario development , This step is often the core step to realize the leap of programming ability .

Judge whether you master the programming language , The simplest criterion is whether the programming language can be used to solve specific problems in the production scenario , The lack of programming scenarios is often one of the biggest obstacles faced by Self-taught programming students , Especially the students who are not majoring in computer science .
