Question

Binary Search Tree implementation of DictionaryADT. The only public functions in the Binary Search Tree files are the ones implemented from DictionaryADT. For comparing two things just use (((Comparable<K>)key).compareTo(x.key) < 0) for something like (key < x.key). The iterators must be fail fast. Use the functions provided

import java.util.Iterator;

import java.util.NoSuchElementException;

public interface DictionaryADT<K,V> {

// Returns true if the dictionary has an object identified by

// key in it, otherwise false.

public boolean contains(K key);

// Adds the given key/value pair to the dictionary. Returns

// false if the dictionary is full, or if the key is a duplicate.

// Returns true if addition succeeded.

public boolean insert(K key, V value);

// Deletes the key/value pair identified by the key parameter.

// Returns true if the key/value pair was found and removed,

// otherwise false.

public boolean remove(K key);

// Returns the value associated with the parameter key. Returns

// null if the key is not found or the dictionary is empty.

public V getValue(K key);

// Returns the key associated with the parameter value. Returns

// null if the value is not found in the dictionary. If more

// than one key exists that matches the given value, returns the

// first one found.

public K getKey(V value);

// Returns the number of key/value pairs currently stored

// in the dictionary

public int size();

// Returns true if the dictionary is at max capacity

public boolean isFull();

// Returns true if the dictionary is empty

public boolean isEmpty();

// Returns the Dictionary object to an empty state.

public void clear();

// Returns an Iterator of the keys in the dictionary, in ascending

// sorted order. The iterator must be fail-fast.

public Iterator<K> keys();

// Returns an Iterator of the values in the dictionary. The

// order of the values must match the order of the keys.

// The iterator must be fail-fast.

public Iterator<V> values();

}

Explanation / Answer

Hey i had done my Data Structure Assignments on JAVA BST which is 95% similar to your requirements. You only need to make variable name changes and other basic changes to fit in.

If you want i can e-mail you my assignment.

Thanks
