A Console-based program to print tree of folders and files of any given path.

Besides, This project provides the implementation of Tree ADT that acts as a Set (Collection) and can be reused in any other projects. Moreover, the Tree ADT supports weight along each edge. The source code for the Tree and its components is located at ..\commandLineTree\src\logicLayer\tree\

The Tree ADT implementation supports some methods such as:

• Get subtree of a node
• Move subtree of node A to node B
• AddNode(To parent, From Child)
• Get value (label) at given index in pre-order traversal
• Find the lowest common ancestor of two given labels
• Pre-order Traversal
• Get level of a node
• Get height of a node
• and many more...

• run Client.java which is located at the path ..\commandLineTree\src\client\Client.java

• Initialize new Tree instance: Tree<data_type> t = new Tree<>()
• Add new label to the tree: t.add(18)

See test.java for more.

For some environments such as Windows cmd or Eclipse, the program may not be displayed correctly due to the use of extended ASCII characters. Please use any text file encoding in your IDE that supports extended ASCII like UTF-8. For example, in Eclipse:

Besides, IntelliJ IDEA has no display problem when running the program.

• This program redesigns Dr. Le, Minh Duc's fundamental design (Node - Edge) to implement the abstract data type Tree (ADT).
• It also implements Java's Set interface.
• A feature that stands out from the prototype design is:
  Instead of using two Vector properties to store Node and Edge, the program is built around two HashMap properties to reduce time complexity while traversing the tree.

Specifically, The first HashMap attributes is HashMap<Node<E>, Edge<E>> parentEdges.
This property allows edge storage that connects a node to its parent node. With something similar to a while loop, it is possible to trace the edges of each node to the ancestral nodes all the way to the root of the tree.

The Second HashMap attributes is HashMap<Node<E>, List<Edge<E>>> properF1DescEdges. It records each node's edges to its "F1" child nodes.

Enter the path of the desired folder.

There is an optional argument when typing your path to style the Tree: -s.

A Complete syntax should be --path [-s]

For example:
C:/your-path/a-folder/ -s

With this argument, It is possible to distinguish between directory and file.
