Question
A concrete class is a class from which instances (or objects) can be created.
True or False?
Select one:
- True
- False
Solution
Final Answer
True
Explanation
A concrete class is defined as a class that can be instantiated, meaning it can create objects. Unlike abstract classes, which cannot be instantiated directly and are intended to provide a base for other classes to inherit from, concrete classes contain complete implementations for their methods and properties. Therefore, when you declare an object of a concrete class, you can use it to access the methods and attributes defined within that class.
For example, in a programming language like Java, if you have a class named Car
that has methods and attributes such as drive()
and color
, you can create an object of the Car
class as follows:
Car myCar = new Car();
In this statement, myCar
is an instance of the concrete class Car
. Hence, the statement that a concrete class is a class from which instances can be created is indeed true.
