public class ArraySet

extends java.util.ArrayList

implements java.util.Set

A resizable-array implementation of the Set interface from the Sun Microsystems collections framework. A set cannot contain duplicate elements.

For the Sun Microsystems util package documentation, see Package java.util. For more general information on the collections framework, see the Sun Microsystems Collections Framework documentation.

Constructor Summary

ArraySet()
Creates an empty set.

ArraySet(java.util.Collection c)
Creates a set that contains all of the elements of the specified Collection in the order returned by the iterator of the Collection.

ArraySet(int initialCapacity)
Creates an empty set whose size is the specified initial capacity.

Method Summary

boolean	add(java.lang.Object o) Adds the specified element to the end of the set if the element is not already present in the set.
boolean	equals(java.lang.Object o) Determines if the specified Object contains the same set of elements as this ArraySet.
int	hashCode() Returns the hash code value for the ArraySet, which is the sum of all of the hash codes of the elements of the set.

Constructor Detail

ArraySet

public ArraySet()

Creates an empty set.

ArraySet

public ArraySet(java.util.Collection c)

Creates a set that contains all of the elements of the specified Collection in the order returned by the iterator of the Collection.

Parameters:

c - The Collection the elements of which you want the ArraySet to have.

ArraySet

public ArraySet(int initialCapacity)

Creates an empty set whose size is the specified initial capacity.

Parameters:

initialCapacity - An integer that specifies an initial size for the ArraySet.

Method Detail

add

public boolean add(java.lang.Object o)

Adds the specified element to the end of the set if the element is not already present in the set.

Specified by:

add in interface java.util.Set

Overrides:

add in class java.util.ArrayList

Parameters:

o - The element to add to the set.

Returns:

true if this method adds the element to the set and false otherwise.

equals

public boolean equals(java.lang.Object o)

Determines if the specified Object contains the same set of elements as this ArraySet.

Specified by:

equals in interface java.util.Set

Overrides:

equals in class java.util.AbstractList

Parameters:

o - The Object to compare to the ArraySet.

Returns:

true if the elements of the ArraySet are the same as the specified Object and false otherwise.

hashCode

public int hashCode()

Returns the hash code value for the ArraySet, which is the sum of all of the hash codes of the elements of the set. The hash code of a null element is defined as zero.

Specified by:

hashCode in interface java.util.Set

Overrides:

hashCode in class java.util.AbstractList

Returns:

The hash code value for the ArraySet.
