Java programming

[画像:a) Create a TreeNode class with the following methods: default constructor, two overloaded constructors, copy constructor, getValue, getLeft, getRight, setValue, setLeft, setRight b) Create a BTInterface with the following abstract methods: getRoot, setRoot, isEmpty, swapSubtrees, singleParent, preorder, postOrder, inOrder, insert c) Create an abstract Binary Tree class that implements the interface. Include the default constructor, a private helper method called checkNode for singleParent() and toString. Make insert an abstract method. d) Derive a Binary Search Tree class from Binary Tree with the following methods: default constructor, overloaded constructor (use a variable length parameter), insert, e) Create a TreeDemo class that creates two BinarySearch Tree objects. Use default and overloaded constructors. For tree one: call the methods makeTree (makes a complete tree), print Tree, swap Subtrees, print Tree. Simliar for tree two. Also, print out the number of single parents in each tree. Define make Tree and print Tree in this class.]
