USING JAVA:

You are to create a red-black tree which supports only the operations listed below. All operations should have time complexity O(log n) when there are n items in the tree, this is the guarantee that red-black trees give. The class should be derived from the TreeMap class in java.util

The only operations which this class supports are:

public boolean is Empty()

public void makeEmpty()

public void insert(Comparable x) throws DuplicateItem

public void delete(Comparable x) throws ItemNotFound

public void deleteMin() throws ItemNotFound

public void deleteMax() throws ItemNotFound

public Object find(Comparable x) throws ItemNotFound

public Object findMin() throws ItemNotFound

public Object findMax() throws ItemNotFound

Your class should be named RBTree

Notes

In no particular order

TreeMap expects Object and the requirement for RBTree is Comparable

TreeMap doesn't throw any reasonable checked exceptions. Your RBTree class does.

TreeMap expects to perform a mapping of keys to data. RBTree doesn't. You may find this to present a problem if you're not careful in the way you implement some of the methods.

The methods in the above list are the only methods that RBTree supports.
