- Is it ever justified to declare a class abstract if it lacks abstract methods? Examine this.Can an abstract class have concrete (non-abstract) methods? Can a concrete class have abstract methods? Can you have an abstract class without abstract methods? Justify your answers.Describe the concept of the "Liskov Substitution Principle" in the context of method overriding. Why is it important, and how does it ensure the proper behavior of derived classes?
- Java Abstract classes can be defined without any abstract methods" - Support this statement with proper reasoning.The parent class is A, and its subclasses are B and C. Now, B and C share several characteristics and methods, but their implementations of some of their methods are drastically different. Using logic, define what A will be - a concrete class, an abstract class, or an interface.In order to qualify as a subclass of an abstract class, a class must offer concrete implementations for all of the abstract methods defined in the abstract parent class. Exactly how do you feel about this?
- Abstract classes and interfaces can both be used to specify common behavior of objects.How do you decide whether to use an interface or an abstract class? Explain youranswer.Give me a code example where you can decouple the classes with the help of Interface? II. Give a code example to show the difference between an abstract class and Interface? III. Give a code example to show the implementation of Abstraction Principle?With appropriate examples, explain the features of static class members.
