Can an object of an abstract class be created in Java?

Description: An abstract class is a class that cannot be instantiated directly. It is used as a base class for other classes to inherit from. Attempting to create an object of an abstract class will result in a compile-time error.

Code example:

abstract class Animal {

public abstract void sound();

}

class Dog extends Animal {

public void sound() {

System.out.println("Woof");

}

}

public class Main {

public static void main(String args[]) {

Animal animal = new Animal(); // error: Animal is abstract; cannot be instantiated

}

}

Debugging steps:

1. Check that the class being instantiated is not an abstract class.

2. If the class is an abstract class, check that it is being used correctly as a base class for other classes to inherit from.

3. If an object needs to be created for the abstract class, create a subclass that extends the abstract class and override any abstract methods.

Extra information:

• Abstract classes are often used to define common functionality for a group of related classes.

• An abstract class can contain both abstract and non-abstract methods.

• Abstract classes cannot be marked as final.
