Object-Oriented Java


Perfect! Now that we have a main method in our class, we're ready to start using the Dog class.

To use the Dog class, we must create an instance of the Dog class. An instance of a class is known as an object in Java.

The example below demonstrates how to create a Car object:

class Car { int modelYear; public Car(int year) { modelYear = year; } public static void main(String[] args){ Car myFastCar = new Car(2007); } }

In the example above, we create a Car object named myFastCar. When creating myFastCar, we used the class constructor and specified a value for the required int parameter year.

2007 is the model year of myFastCar. Note that we declared the new object inside the main method.
