Question

I want to force any class not to be able to create a new instance if it inherits a specific base class, so how this base class should look like?

Answer 1

The following code is in java. just to give you an Example

Base class has an exception on the constructor.

public class BaseClass 
{
    public BaseClass()
    {
        throw new AssertionError();
    }
}

The child class extending the base class but if you create an object of it it will give u an exception.

public class MainClass extends BaseClass 
{
    public MainClass()
    {

    }

    public static void main(String[] args) {
        MainClass c = new MainClass();
    }
}
