Java Inheritance Exercises 7

Write a Car class, with the final type of property brand, with function drive;

Define its subclasses Aodi and Benchi, with attributes: Price, model, function: variable speed;

Define main class E, create aodi and Benchi objects separatelyin their main method, and test the object's special

Of
