D. Buddy 6)Why are instance variables accessible throughout the class? A. They are declared within the class scope. B. They can only store primitive types. C. They have a fixed memory size. D. They are automatically initialized 7)How does Object-Oriented Programming (00P) model applications? A. 00P models applications as a single monolithic structure without any components 8. 00P models applications as a linear sequence of instructions executed one after another. c OOP models applications as a system of collaborating objects with properties and behaviors. D. OOP models applications by focusing solely on data storage without behavior. 8) How do you assign a newly created Dog instance to a variable? A. Dogeffie; B Dogeffie=newDog(1) C. Dogeffie=Dog(1) D Dogeffie=newDog; 9)How can methods in Java accept instances as parameters? A. Methods can only accept primitive data types as parameters B. Methods can accept arrays but not instances of classes C. Methods can accept instances but only if they are static D. Methods can accept instances as parameters 10) What is encapsulation in OOP? A. It is a way of combining various data members and member functions that operate on those data members into a single unit B. It is a way of combining various data members and member functions into a single unit which can operate on any data is a way of combining various data members into a single unit D. It is a way of combining various member functions into a single unit

6) The correct answer is A. Instance variables are accessible throughout the class because they are declared within the class scope. Instance variables are non-static variables declared within a class but outside any method or constructor. Since they are declared within the class scope, they can be accessed from any method or constructor within the class.<br /><br />7) The correct answer is C. Object-Oriented Programming (OOP) models applications as a system of collaborating objects with properties and behaviors. OOP is a programming paradigm that focuses on modeling real-world objects and their interactions. In OOP, applications are modeled as a collection of objects that have their own properties (data) and behaviors (methods). These objects can interact with each other to perform various tasks.<br /><br />8) The correct answer is B. To assign a newly created Dog instance to a variable, you need to use the `new` keyword followed by the class name and parentheses. The correct syntax is `Dog obj = new Dog();`. This creates a new instance of the Dog class and assigns it to the variable `obj`.<br /><br />9) The correct answer is D. Methods in Java can accept instances as parameters. This means that you can pass an object of a class as an argument to a method. This allows you to access the properties and behaviors of the instance within the method.<br /><br />10) The correct answer is A. Encapsulation in OOP is a way of combining various data members and member functions that operate on those data members into a single unit. Encapsulation is one of the fundamental principles of OOP, and it involves bundling related data and functions together. This helps to hide the internal details of an object and provides a way to interact with the object through its public interface.
