Today is to learn Java code on the third day, today's study is focused on the switch case and circulation structure , in the afternoon while loop and the do while loop using a little, so the focus to review it again at night, today didn't finish writing, note upload tomorrow,
SAO lei teacher lecture interesting, to a great , found SAO lei teacher, for example, all love to use to eat, have the suspicion of version , for example for
