Objects

What are they?

• An object is a specific instance of a class.

Object creation

Dog bubbles = new Dog(2, Sex.FEMALE, "Bubbles", 10.5);
Dog rocky = new Dog(5, Sex.MALE, "Rocky", 5.9);

• Bubbles and Rocky are objects, they have state as defined in the brackets, which can be used by the methods/behaviour.

• Now we have instances of the class, we can use their methods.

  • We can ask bubbles and rocky to run, and they will get the message (ie method) and perform that behaviour (run that method)
