See Also:   Hashtable since:    1.0 Constructor Summary public   Dictionary()      Constructs a new instance of this class. Method Summary abstract public  Enumeration<V> elements()      Answers an Enumeration on the elements of this Dictionary. abstract public  V get(Object key)      Answers the value associated with key. abstract public  boolean isEmpty()      Answers if this Dictionary has no key/value pairs, a size of zero. abstract public  Enumeration<K> keys()      Answers an Enumeration on the keys of this Dictionary. abstract public  V put(K key, V value)      Associate key with value in this Dictionary. abstract public  V remove(Object key)      Remove the key/value pair with the specified key from this Dictionary. abstract public  int size()      Answers the number of key/value pairs in this Dictionary. Constructor Detail Dictionary public Dictionary()(Code) Constructs a new instance of this class. Method Detail elements abstract public Enumeration<V> elements()(Code) Answers an Enumeration on the elements of this Dictionary. an Enumeration of the values of this Dictionary See Also:   Dictionary.keys See Also:   Dictionary.size See Also:   Enumeration get abstract public V get(Object key)(Code) Answers the value associated with key. Parameters:   key - the key of the value returned the value associated with key or nullif the specified key does not exist See Also:   Dictionary.put isEmpty abstract public boolean isEmpty()(Code) Answers if this Dictionary has no key/value pairs, a size of zero. true if this Dictionary has no key/value pairs, false otherwise See Also:   Dictionary.size keys abstract public Enumeration<K> keys()(Code) Answers an Enumeration on the keys of this Dictionary. an Enumeration of the keys of this Dictionary See Also:   Dictionary.elements See Also:   Dictionary.size See Also:   Enumeration put abstract public V put(K key, V value)(Code) Associate key with value in this Dictionary. If key exists in the Dictionary prior to this call being made, the old value is replaced. Parameters:   key - the key to add Parameters:   value - the value to add the old value previously associated with key ornull if key is new to theDictionary.
