What are some examples of concrete classes in programming?

What are some examples of concrete classes in programming?

Concrete classes are classes that can be instantiated. For example, in Java, a class like 'Car' that implements methods and properties is a concrete class.

Can you give me more examples in different programming languages?

Sure! In Python, a concrete class could be 'Dog' with methods like 'bark()' and 'fetch()'. In C#, 'Employee' with properties like 'Name' and 'ID' is another example.

What is the difference between an abstract class and a concrete class?

An abstract class cannot be instantiated and may contain abstract methods without implementation, while a concrete class can be instantiated and has complete method implementations.

Are there any best practices for designing concrete classes?

Yes! Keep your classes focused on a single responsibility, use clear naming conventions, and ensure they are easy to test.
