Class Hashtable

public class Hashtable extends Object

The main hash-table implementation

Constructor Summary
	Hashtable(int initialCapacity, float loadFactor) Constructs a new, empty hashtable with the specified initial capacity and the specified load factor.
	Hashtable(int initialCapacity) Constructs a new, empty hashtable with the specified initial capacity and default load factor.
	Hashtable() Constructs a new, empty hashtable with a default capacity and load factor.

Method Summary
void	clear() Clears this hashtable so that it contains no keys.
boolean	contains(Object value) Tests if some key maps into the specified value in this hashtable.
boolean	containsKey(Object key) Tests if the specified object is a key in this hashtable.
Enumeration	elements() Returns an enumeration of the values in this hashtable.
Object	get(Object key) Returns the value to which the specified key is mapped in this hashtable.
boolean	isEmpty() Tests if this hashtable maps no keys to values.
Enumeration	keys() Returns an enumeration of the keys in this hashtable.
Object	put(Object key, Object value) Maps the specified `key` to the specified `value` in this hashtable.
Object	remove(Object key) Removes the key (and its corresponding value) from this hashtable.
int	size() Returns the number of keys in this hashtable.
String	toString() Returns a rather long string representation of this hashtable.

Constructor Detail

public Hashtable(int initialCapacity, float loadFactor)

Constructs a new, empty hashtable with the specified initial capacity and the specified load factor.

public Hashtable(int initialCapacity)

Constructs a new, empty hashtable with the specified initial capacity and default load factor.

public Hashtable()

Constructs a new, empty hashtable with a default capacity and load factor.

public void clear()

Clears this hashtable so that it contains no keys.

public boolean contains(Object value)

Tests if some key maps into the specified value in this hashtable. This operation is more expensive than the containsKey method.

public boolean containsKey(Object key)

Tests if the specified object is a key in this hashtable.

public Enumeration elements()

Returns an enumeration of the values in this hashtable. Use the Enumeration methods on the returned object to fetch the elements sequentially.

public Object get(Object key)

Returns the value to which the specified key is mapped in this hashtable.

public boolean isEmpty()

Tests if this hashtable maps no keys to values.

public Enumeration keys()

Returns an enumeration of the keys in this hashtable.

public Object put(Object key, Object value)

Maps the specified key to the specified value in this hashtable. Neither the key nor the value can be null.

The value can be retrieved by calling the get method with a key that is equal to the original key.
