Design a Java program to read the file system beneath a particular folder, and store it in a tree data structure.

Description:

• Requirements: the program should be able to look at a folder and its tree of subfolders, and construct a tree data structure to represent it. Each node in the tree corresponds to a folder in the file system and should contain the number of files, the total size of the files, the folder's name, and a list of child folders
• the program should read the name of the folder to scan, scan the folder's subtree, then output the tree in a way that shows the tree hierarchy e.g., one line per tree node, and indent each node appropriately
• Hint: it should use recursion both in the scanning part of the program, and the part that outputs the tree
