I'm looking for a way to get the name of an object instance at run-time. Is it possible to to determine the class name (as a string) of an instance? i.e. is there an Apex equivalent of the Java myInstance.getClass().getName() or any tricks to achieve just that?

Voting for the idea Method to get the Type of an Object (also Primitive Type not only SObject) would be a good long term solution.

You can use something like below:

String.valueOf(this).substring(0,String.valueOf(this).indexOf(':'));

instanceOf verifies at runtime whether an object is actually an instance of a class...but you would have to write the conditions to check for them all. Also getSObjectType will describe an sObject.
