Because in 2019, half of the semester Java teacher asked us to do a simple student management system, then for me, this system is very difficult, after all, have their own encoding a man from design to completion, but not a lot of knowledge too familiar, was still spending a lot of time to do this system is the first time its own independent made a full console with a file of student management systems . The original is not easy, and so want to be recorded, but has not taken the time to do this. Now just a holiday, this time holding on to write, record it. Just a few days before setting up my personal blog, so this article also simultaneously record up to my personal blog: BitHachi welcomed everyone to visit my blog, the latter will write a lot of articles, I hope everyone can learn together and exchange .
