Enum是计算机编程语言中的一种数据类型---枚举类型。 在实际问题中，有些变量的取值被限定在一个有限的范围内。 例如，一个星期内只有七天 我们通常这样实现上面的定义：
public String monday;
public String tuesday;
public String wensday;
public String thursday

在使用下面的命令是可以通过--help来获取更多的信息1,查询当前目录文件列表：ls
ls命令默认状态下将按首字母升序列出你当前文件夹下面的所有内容，但这样直接运行所得到的信息也是比较少的，通常它可以结合以下这些参数运行以查询更多的信息：
ls / 显示/.下的所有文件和目录
ls -l 给出文件或者文件夹的详细信息
ls -a 显示所有文件，包括隐藏文
