Dynamic equivalent of the Java language CAST operator

Question

Hello,
Here is what I want to do:
I have an Object that contain "something" (I don't know at compilation time). And I want to do this call:
Object myObject = new String("Hello");
myMethod (myObject);
having declared these:
public void myMethod (Integer dInt);
public void myMethod (String sString);
I want the second method to be called. How can I do that?
I'm looking for something like a dynamic equivalent of the Java language cast operator:
??? myMethod ( (myObject.getClass())myObject ); ???
or ?? myMethod ( (myObject.castTo(myObject.getClass()) ) ; ??
Thanks.

How 'bout using the instanceof operator?
Like this:
public myMethod(Object obj)
if (obj instanceof String)
//do String stuff
else if (obj instanceof Integer)
//do Integer stuff
}
