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

Parameters:

initialCapacity - int the initial number of buckets

Method Details

clear

public void clear()

Clears the hash table so that it has no more elements in it.

containsKey

public boolean containsKey(long key)

Returns true if the collection contains an element for the key.

key - long the key that we are looking for

Returns:

boolean

hash

public int hash(long key)

Parameters:

key - long

Returns:

int the hash code corresponding to the key value

put

public int put(long key,
 int value)

int value

putIfAbsent

public int putIfAbsent(long key,
 int value)

Puts the specified element into the hashtable, using the specified key. The element may be retrieved by doing a get() with the same key.

Parameters:

key - long the specified key in the hashtable

value - int the specified element

Returns:

int value

size

public int size()

Returns the number of elements contained in the hashtable.
