What will be an ideal response?
An abstract method is one with keyword abstract in its declaration. Abstract meth- ods do not provide implementations. Each concrete subclass of an abstract superclass must provide concrete implementations of the superclass’s abstract methods. An abstract method is appropriate when it does not make sense to provide an implementa- tion for a method in a superclass (i.e., some additional subclass-specific data is required to implement the method in a meaningful manner).
