组合模式，完整代码及运行结果截图

题目：



文件系统中有文件, 也有文件夹(其实是特殊的文件), 文件和文件夹组合在一起, 可以成为一个更大的文件夹. 在用户看来,不管是文件, 还是文件夹, 还是更目录, 对它们的操作都是一致的(当然试图把一个文件夹放到文件下面是不容许的). 这就是说整体和部分具有一致的接口.

要求应用Composite模式来实现文件系统的文件/目录结构.-Combination mode of operation results capture the full code and title: the file system to file, there are folders (in fact, a special file), files and folders together, can become a bigger folder. In the user view, Whether the file or folder, or more directory operations on them are the same (of course tried to put a folder in the file the following is not allowed). This means that the whole and part with a consistent interface. requires the application of Composite model for file system file/directory structure.
