This is the idea that I have developed over the years, perhaps biased, but I can quickly understand a programmer based on the programming language a person likes. When I read my resume, I try to use m
As we move firmly towards the Sdn world, it becomes increasingly obvious that in the SDN world, engineers need to learn more skills, including the SDN programming language. Of course, it's great to be able to master every programming language, but in fact most people may not have that much time and interest to learn each language. Then there are three major SDN programm

understand and use it. Internal classes and anonymous classes lead to confusing code. Lack of effective destructors makes it difficult to manage other resources, such as mutexes and locks, in addition to memory. Java threads are unreliable and the I/O mechanism is powerful, but it is cumbersome to read a text file.
Java does not have a mechanism to manage the library version, and thus formally repeating the mistakes of the Windows DLL Hell. In an environment like application servers, this raise
