"><p>Compares this instance with the specified object and indicates if they
 are equal. In order to be equal, <code>o</code> must represent the same object
 as this instance using a class-specific comparison. The general contract
 is that this comparison should be reflexive, symmetric, and transitive.
 Also, no object reference other than null is equal to null.

 <p>The default implementation returns <code>true</code> only if <code>this ==
 o</code>. See <a href="../../../../../reference/java/lang/Object.ht
