The given code demonstrates the use of inheritance and method overriding in Java. Here’s a breakdown:
- The
Engineclass is defined with two attributes:model(without restricted access) andmaxPower(with restricted access within theEngineclass). - The
getModel()method is used to retrieve the value of themodelattribute. - The
setModel(String newModel)method is used to assign a new value to themodelattribute. - The
setMaxPower(int newMaxPower)method is declared as an abstract method, which means it must be implemented by any subclass that extends theEngineclass. - The
Dieselclass inherits from theEngineclass using the keywordextends. - In the main method of the
Dieselclass, an object of type Diesel named “vw” is created. - The setModel() method is called on “vw” to set its model to “VW”.
- The setMaxPower() method is implemented in Diesel by overriding the abstract method from Engine.
- Finally, the getModel() method is called on “Diesel” object and its result is printed.
Note: It seems there might be some issues with syntax errors in your code (e.g., missing data types for variables, incorrect parameter name in setMaxPower()). Please ensure that you have properly defined your classes and fixed any compilation errors before running it.
