In this part, you have been asked to create a simple ADT tree. A company asked you to create a tree like the following: As you can see you need the following: a Worker.java class, that only have name and salary attributes, you should have a constructor for this class. You need a Binary TREE ADT class to hold the tree. The Tree elements can have no children or many children (0,1,2,3,) A binary tree ADT needs the following Name of the method Possible* signature of the method Explanation Example Constructor Optional root() public static Worker root() Returns the root of the tree (or null if empty). [Returns object of Worker Type] parent(p) public static Worker parent(Worker p) Return the parent of worker p left(p) public static Worker left(Worker p) Return the left child of worker p right(p) public static Worker right(Worker p) Return the right child of worker p setLeft(p) public static Worker setLeft(Worker p) Set the left child of worker p setRight public static Worker setRight(Worker p) set the right child of worker p size() Return the size You need to also write a method to print the tree (nothing fancy!!) o You may do it in-order, preorder, Last part, create a main o create the workers with their name and salary o Add them to the tree similar to image, remember to use setLeft and setRight o Lastly use your print and print the tree
