Topic: Data Structures - Trees and Graphs using java language

Dear sir, please give me the methods for all of the tasks asked below done in java language. They are short tasks each will contain in one java class, I will be grateful to you as i dont have any more questions left ,I needed to post all at once, I'm sorry for that. Please do not copy from other chegg solves or resources as it will lead to plagiarism, I will give you big upvote. Take your time, thanks in advance :)

Please provide the screenshots of outputs with code ran in an ide for better understanding, , do not provide handwritten codes please thanks. :)

Instructions that are necessary are in the pic.

(For the below tasks, you may want to create a binary tree manually and use the same tree for all of these tasks. However, for task 6, you need two trees; hence, prepare another) NB: All the methods(1-7) as well as the main method/tester statements must be written in one class. DO NOT write a different class for each method. Compile all your codes and simulation picture in ONE PDF and submit it. 1. RECURSIVELY calculate the height of a tree. 2. RECURSIVELY calculate the level of a Node in a tree. 3. Print elements of all the Nodes of a tree using Pre-order Traversal. 4. Print elements of all the Nodes of a tree using In-order Traversal 5. Print elements of all the Nodes of a tree using Post-order Traversal. 6. Write a method which will evaluate whether two trees are exactly same or not. 7. Write a method which will return a copy (new tree) of a given tree
