We started to learn java last semester in senior three, but few people learned it. I taught myself java in my freshman year. Our major is computer science and technology, and we learn everything, from software to hardware, from graphics and images to network composition. Database, operating system, data structure, electronic logic, etc. Are all open. I started to learn C language in my freshman year, and then I started to learn java in my senior year. I feel that college is mainly self-study.
