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.elements()
Returns an enumeration of the values in this hashtable.Returns the value to which the specified key is mapped in this hashtable.boolean

Method Details
-
size
public int size()Returns the number of keys in this hashtable. -
isEmpty
public boolean isEmpty()Tests if this hashtable maps no keys to values. -
keys
Returns an enumeration of the keys in this hashtable. -
elements
Returns an enumeration of the values in this hashtable. Use the Enumeration methods on the returned object to fetch the elements sequentially. -
contains
Tests if some key maps into the specified value in this hashtable. This operation is more expensive than thecontainsKey
method. -
containsKey
Tests if the specified object is a key in this hashtable. -
get
Returns the value to which the specified key is mapped in this hashtable. -
put
Maps the specifiedkey
to the specifiedvalue
in this hashtable. Neither the key nor the value can benull
.The value can be retrieved by calling the
get
method with a key that is equal to the original key. -
remove
Removes the key (and its corresponding value) from this hashtable. This method does nothing if the key is not in the hashtable. -
clear
public void clear()Clears this hashtable so that it contains no keys. -
toString
Returns a rather long string representation of this hashtable. Handy for debugging - leave it here!!!
