Is it compulsory for a class, which has been declared as abstract, to have at least one abstract method?arrow_forwardJAVA: Briefly describe (1-2 sentences) each of the following object-oriented programming concepts: Attributes Methods Primitive Data Types vs. Objects Static methods/variables vs. non-staticarrow_forward
- Which of the following best describes data encapsulation in Object-Oriented Programming? A. The process of inheriting properties from a base class. B. The bundling of data with the methods that operate on that data. C. The ability of different classes to use the same method name. D. The concept of restricting access to the direct modification of an object's attributes.arrow_forwardwhy might we write public get and set methods for private properties? hint: you may want to do a quick internet search for "java getters and setters pros and cons." 1. these public methods give us a way to read and write the values of these properties in a controlled way 2. they make a program run more efficiently 3. if we didn’t, there would be no way to read or write the values of the properties 4. object-oriented languages require us to do thisarrow_forwardWrite 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.
