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 whether the specified Object contains the same set of elements as this ArraySet.
int	hashCode() Gets 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 - A Collection that has the elements that 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.Collection

Specified by:

add in interface java.util.List

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:

A boolean that is true if this method adds the element to the set or false if it does not.

equals

public boolean equals(java.lang.Object o)

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

Specified by:

equals in interface java.util.Collection

Specified by:

equals in interface java.util.List

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:

A boolean that is true if the elements of the ArraySet are the same as the specified Object or false if they are not.

hashCode

public int hashCode()

Gets 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 zero.

Specified by:

hashCode in interface java.util.Collection

Specified by:

hashCode in interface java.util.List

Specified by:

hashCode in interface java.util.Set

Overrides:

hashCode in class java.util.AbstractList

Returns:

An integer that is the hash code value for the ArraySet.
