What technology to learn to make money, how to learn (what to learn first, what to learn), willing to suffer hardships, and have a certain foundation of C, c++, Java, please give some advice. Thank you. Technology, more, automobile, beauty, electrician, fitter, etc. Of course, you have a certain computer foundation, so go to a white-collar class. C++ and Java are more profitable. Among them, getting started with Java will be a little easier. I suggest you go to a special IT education center, consult and take a test to see what you are suitable for.
