abstract / non abstract class

There is an abstract class and I only remove the keyword abstract.
Is the class functionality the same as before except for ability to be instantiated? Or is there anything more?
Thank you.

Assuming there were no abstract methods in the class then the functionality will not have changed.
If there were abstract methods then you will need to implement these and by implementing them you are obviously changing the functionality.

If there are no abstract methods in the class, then you will be able to instantiate the Class.

If the class contains even one abstract method then the class needs to be marked as abstract otherwise it wont compile.

Yes, I know this. Thank you.
