- Provide real-world examples and contexts where implementing a custom Comparator for a class that already implements the Comparable interface would be necessary.Write the definition of classes and interfaces in the given diagram using following details: a) Interface shape has a method draw(). b) Override the method draw() in all subclasses. c) Define a non-abstract method fillColor() in Circle class. (I want the complete solution using the codes in bluej program also diagram) bluej java coodProvide an example of why you might prefer an interface over an abstract class. Additionally, describe a situation in which you would prefer an abstract class to an interface.
- Write the definition of classes and interfaces in the given diagram using following details: a) Interface shape has a method draw(). b) Override the method draw() in all subclasses. c) Define a non-abstract method fillColor() in Circle class. (I want the complete solution using the codes in bluej program also diagram) bluejDiscuss the potential issues and pitfalls that can arise when overriding methods in a class hierarchy, and how to avoid them.A is a parent class whereas B and C are subclasses of A. Now, B and Cshare some common attributes and some common methods, but there are somemethods in B and C that have very different implementations. Explain with reason whatA is going to be - a concrete class or an abstract class or an interface.
