equals</H3>
<PRE>
public boolean <B>equals</B>(<A HREF="../../java/lang/Object.html">Object</A>&nbsp;o)</PRE>
<DL>
<DD>Compares the specified object with this set for equality.  Returns
 <tt>true</tt> if the given object is also a set, the two sets have
 the same size, and every member of the given set is contained in
 this set.  This ensures that the <tt>equals</tt> method works
 properly across different implementations of the <tt>Set</tt>
 interface.<p>

 This implementation first checks if the specified object is this
 set; if so it returns <tt>true</tt>.  Then, it checks if the
 specified object is a set whose size is identical to the size of
 this set; if not, it it returns false.  If so, it returns
 <tt>containsAll((Collection) o)</tt>.<DD><DL>

<A NAME="hashCode()"><!-- --></A><H3>
hashCode</H3>
<PRE>
public int <B>hashCode</B>()</PRE>
<DL>
<DD>Returns the hash code value for this set.  The hash code of a set is
 defined to be the sum of the hash codes of the elements in the set.
 This ensures that <tt>s1.equals(s2)</tt> implies that
 <tt>s1.hashCode()==s2.hashCode()</tt> for any two sets <tt>s1</tt>
 and <tt>s2</tt>, as required by the general contract of
 Object.hashCode.<p>

 This implementation enumerates over the set, calling the
 <tt>hashCode</tt> method on each element in the collection, and
 adding up the results.<DD><DL>

removeAll</H3>
<PRE>
public boolean <B>removeAll</B>(<A HREF="../../java/util/Collection.html">Collection</A>&nbsp;c)</PRE>
<DL>
<DD>Removes from this set all of its elements that are contained in
 the specified collection (optional operation).<p>

 This implementation determines which is the smaller of this set
 and the specified collection, by invoking the <tt>size</tt>
 method on each.  If this set has fewer elements, then the
 implementation iterates over this set, checking each element
 returned by the iterator in turn to see if it is contained in
 the specified collection.  If it is so contained, it is removed
 from this set with the iterator's <tt>remove</tt> method.  If
 the specified collection has fewer elements, then the
 implementation iterates over the specified collection, removing
 from this set each element returned by the iterator, using this
 set's <tt>remove</tt> method.<p>

 Note that this implementation will throw an
 <tt>UnsupportedOperationException</tt> if the iterator returned by the
 <tt>iterator</tt> method does not implement the <tt>remove</tt> method.<DD><DL>
