day01_03常用的命令行操作
学java也是一样，语法格式，书写规范同样是需要从头来学的，唯一多的就是编程的那种感觉。而这种感觉，随着你的的从无到有，也是一定会有的。不认识有多少人爱看《星球大战》，我就是个星战迷，当然这不是重点。在第二部里，尤达说了一句话，我觉得很有深意。他说，有时候你需要忘掉以前学过的工具。事实上，大家发现那些自学成才的程序员，有一些马马虎虎，有一些则出类拔萃。但也有一些是养成了很糟糕的习惯，这就好比文笔很差。一般状况下，一个文笔很差的人，想变成大作家比从未写过文章的人比，还要困难。因为你要摒弃那些坏的习惯。所以，如果你有顾虑以前没编过程序，没关系，从零开始。(The same is true for learning Java. Grammar formats and writing specifications also need to be learned from scratch. The only thing that matters is the feeling of programming. And this feeling, as you grow from scratch, will also be there. I don't know how many people like watching Star Wars. I'm a fan of Star Wars. Of course, that's not the point. In the second part, Yoda said something that I thought was very meaningful. He said that sometimes you need to forget the tools you learned before. In fact, we found that some of the self-taught programmers were careless, while others were outstanding. But there are also some bad habits, which is just like poor writing. In general, it is more difficult for a person with poor writing style to become a great writer than for someone who has never written an article. Because you should abandon those bad habits. So, if you have concerns that you haven't programmed before, it doesn't matter. Start from scratch.)
