Lab 2: File System Tree

Due Date and Submission Requirements

Due Date: Friday, January 31st at 11:59 p.m.
Partner Information: This is an individual assignment. You are allowed to collaborate with other students, but each student must submit their individual, independent solution.
Submission Instructions: Upload your solution (FileTree.java), to the BrightSpace(D2L) Lab 2 Dropbox.

The goal of this lab is:

Gain experience using the Tree data structure

Directions

In this lab, you will build three more methods for the FileTree class we have been working on in class (you should download a fresh set of files below) as a starting point. You do not need to change any code beyond what is instructed. Complete the following tasks:

1. Fill in the body for the public String getPath() method. This method will return a String that shows the path from the root to current directory (e.g., ~/School/CSCI232/Labs)

2. Modify the existing method public boolean moveDown(String directory) so that instead of reading in a single directory and moving into that directory, it can read in a path (e.g., Pictures/Pets/Tater) and navigate to the final directory in the path, if it exists. If the path is not valid, it should return false. If part of the path is correct, but other parts are incorrect (e.g., /Pictures/Christmas/2023), the program should remain in the current directory (dont move to /Pictures). You may assume that the path provided is relative to the current directory. Hint: you can use the Java .split(“/”) method on the String path to create a list of all the directories you need to move down into.

3. Fill in the body for the public boolean remove(String directory). This method will remove the selected directory, and all of its subdirectories, from the file system. If the directory does not exist, the method should return false. If it does, remove it and return true. You may assume that the directory provided is a child of the current directory (if it exists).

4. Now test your methods. The FileTreeManager class has the code to run the methods you are writing. getPath() is executed by typing the pwd command, and remove() is execute by typing the rm command. moveDown() is still executed by typing the cd command. There is no code you need to add in this task, but make sure you test your methods before you submit this lab. That is three methods in total.

Required Output

When you run your program with the following commands, it should look exactly like output seen in in this screenshot .

Starting Code

Grading (10 points)

3 points - getPath() is correct.
4 points - moveDown() is correct.
3 points - remove() is correct.

NOTE: If your code does not compile, correctness cannot be verified and you won’t receive any points for your code. Turn in code that compiles!
