Is There a Opposite to .equal() ?

Say I compare two objects, Obj1 and Obj2 with .equals().
<pre>
if( Obj1.equals(Obj2) )
{
// do something
}
</pre>
This works fine and dandy. But what if I want to do the opposite, "not equals"? I have looked at the API and was unable to find anything like ".notEquals()". So what I what I did (I was in a hurry) was:
<pre>
if( Obj1.equals(Obj2) )
{
// do nothing
}
else
{
// do what is desired
}
</pre>
Thanks in advance,
Matt

How about
if ( ! obj1.equals( obj2 ) )

???
