The above two analyses of classes and objects, and how to define objects. The following is an analysis of how objects are used

The following defines a class first

The public class car{//defines the first letter of the class list to be capitalized, and at the same time see knowingly

String name; Attribute names are defined

int price; Define the price

public void Run () {//defines the Run method

System.out.println ("The car is running");

}

public void Stop () {//defines the Stop method

System.out.println ("The car Stopped");

}

}

The class is defined so that the object can be produced by the class

The specific code is as follows:

Car audi = new car ();//define the Audi object, which produces a car by car class

Audi.name= "Audi"; The name of the car is Audi.

The price of the audi.price=400000;//car is 400000.

Audi.run (); Audi and start running

Audi.stop ();//audi, the car's stopped.

The above is how the object is generated by the class, and the run and stop methods of the calling object
