 332  <li>It is <i>reflexive</i>: for any non-null reference value
 333      <code>x</code>, <code>x.equals(x)</code> should return
 334      <code>true</code>.
 335  <li>It is <i>symmetric</i>: for any non-null reference values
 336      <code>x</code> and <code>y</code>, <code>x.equals(y)</code>
 337      should return <code>true</code> if and only if
 338      <code>y.equals(x)</code> returns <code>true</code>.
 339  <li>It is <i>transitive</i>: for any non-null reference values
 340      <code>x</code>, <code>y</code>, and <code>z</code>, if
 341      <code>x.equals(y)</code> returns <code>true</code> and
 342      <code>y.equals(z)</code> returns <code>true</code>, then
 343      <code>x.equals(z)</code> should return <code>true</code>.
 344  <li>It is <i>consistent</i>: for any non-null reference values
 345      <code>x</code> and <code>y</code>, multiple invocations of
 346      <tt>x.equals(y)</tt> consistently return <code>true</code>
 347      or consistently return <code>false</code>, provided no
 348      information used in <code>equals</code> comparisons on the
 349      objects is modified.
 350  <li>For any non-null reference value <code>x</code>,
 351      <code>x.equals(null)</code> should return <code>false</code>.
 352  </ul>
 353  <p>
 354  The <tt>equals</tt> method for class <code>Object</code> implements
 355  the most discriminating possible equivalence relation on objects;
 356  that is, for any non-null reference values <code>x</code> and
 357  <code>y</code>, this method returns <code>true</code> if and only
 358  if <code>x</code> and <code>y</code> refer to the same object
 359  (<code>x == y</code> has the value <code>true</code>).
 360  <p>
 361  Note that it is generally necessary to override the <tt>hashCode</tt>
 362  method whenever this method is overridden, so as to maintain the
 363  general contract for the <tt>hashCode</tt> method, which states
 364  that equal objects must have equal hash codes.

 384 <DD>Returns a hash code value for the object. This method is
 385  supported for the benefit of hashtables such as those provided by
 386  <code>java.util.Hashtable</code>.
 387  <p>
 388  The general contract of <code>hashCode</code> is:
 389  <ul>
 390  <li>Whenever it is invoked on the same object more than once during
 391      an execution of a Java application, the <tt>hashCode</tt> method
 392      must consistently return the same integer, provided no information
 393      used in <tt>equals</tt> comparisons on the object is modified.
 394      This integer need not remain consistent from one execution of an
 395      application to another execution of the same application.
 396  <li>If two objects are equal according to the <tt>equals(Object)</tt>
 397      method, then calling the <code>hashCode</code> method on each of
 398      the two objects must produce the same integer result.
 399  <li>It is <em>not</em> required that if two objects are unequal
 400      according to the <A HREF="http://java.sun.com/javase/6/docs/api/java/lang/Object.html#equals(java.lang.Object)" title="class or interface in java.lang"><CODE>Object.equals(java.lang.Object)</CODE></A>
 401      method, then calling the <tt>hashCode</tt> method on each of the
 402      two objects must produce distinct integer results.  However, the
 403      programmer should be aware that producing distinct integer results
 404      for unequal objects may improve the performance of hashtables.
 405  </ul>
 406  <p>
 407  As much as is reasonably practical, the hashCode method defined by
 408  class <tt>Object</tt> does return distinct integers for distinct
 409  objects. (This is typically implemented by converting the internal
 410  address of the object into an integer, but this implementation
 411  technique is not required by the
 412  Java<font size="-2"><sup>TM</sup></font> programming language.)
