Structure of the MyBSTree Fields • a private field named root of type Node You may implement any additional fields that you may need. Structure of the MyBSTree Methods As described by the UML Class Diagram above, your MyBSTree class must implement the following methods: • a public method named insert that takes an object of type T as an argument and returns nothing • a public method named contians Item that takes an object of type T as an argument and return a boolean • a public method named getSize that takes no arguments and returns an int • a public method named print InOrder that takes no arguments and returns nothing • a public method named toString that takes no arguments and returns a String Note that these methods are declared in the ITree generic interface. You will be implementing these methods in this MyBSTree concrete class. You may implement any additional methods that you may need. You will also need to implement a nested inner class named Node inside of your MyBSTree class. Each Node object will store one piece of data in the binary search tree. The actual data value will be stored in the data field of the Node object. As these are binary Node objects, each Node will also store a reference to a left sub-node and a right sub-node. These references will be stored in the left and right fields. Structure of the Node Fields • a public field named data of type T • a public field named left of type Node • a public field named right of type Node You may implement any additional fields that you may need. Structure of the Node Methods • a public constructor that takes an argument of type T • a public method named insert that takes an argument of type T and returns nothing You may implement any additional methods that you may need. Additional Information MyBSTree 1. This concrete class will store its elements in a collection of linked binary Node objects. 2. insert method o Inserts a new item into the binary search tree in the correct location. • There should be no duplicate items in the tree. If an item is inserted and that item is already in the tree then this method should simply return without changing the state of the tree. 3. containsItem method o Returns true if the tree contains the specified item; otherwise returns false. 4. getSize method o Returns the number of nodes currently stored in this tree. 5. printInOrder method o Prints the items in the tree in a space separated list in ascending order. 6. toString method • Returns a String containing the items in the tree in ascending order and separated by a space. Node 1. Your BSTree class must contain a nested inner class named Node. This class must be declared to be package level (not private or public). 2. parameterized constructor method o initializes the data of the new Node with the argument value. 3. insert method o this is a recursive method that finds the insertion point and inserts a Node for the new item in the correct position in the sub- tree for which this Node is the root. Remember that no duplicate items can be stored in the tree.
