This can be done through inheritance and interfaces.  So if you have an abstract class Mammal and an interface EggLayers, you could write 

  public class SpinyAnteater extends Mammal implements EggLayers

In Java you can extend exactly one class, but you can implement many interfaces.

Good luck!

Hello I just had a question and was wondering if someone can help me out?  I just wanted to know if a object can have several different classes?  If someone knows can they explain to me why this is the case.  I think an object can have several different classes.  If you look at the spiny anteater it is both a mammal and an egg-laying specimen.
