Question 5:

What is an interface in Java?

A) A class that defines a set of methods that another class must inherit

B) A contract that defines a set of methods that a class must implement

C) A collection of classes that provide a common set of methods

D) A type of object that can be used to achieve polymorphism

Explanation:

Answer - B

An interface in Java is a contract that defines a set of methods that a class must implement. It provides a way to achieve abstraction and enables loose coupling between the classes.

Question 6:

What is the advantage of using interfaces in Java?

A) Interfaces enable multiple inheritance in Java

B) Interfaces provide a way to achieve abstraction

C) Interfaces enable tight coupling between classes

D) Interfaces provide a way to achieve encapsulation

Explanation:

Answer - B

One of the key advantages of interfaces is abstraction. Abstraction is the process of hiding the implementation details of a class and exposing only the relevant information to the user. By using interfaces, you can define a set of methods that a class must implement without specifying how those methods are implemented. This enables you to achieve abstraction in your code and create a more modular and maintainable system.

Question 7:

What is polymorphism?

A) The ability of a single object to take on multiple forms

B) The ability of a class to inherit from multiple superclasses

C) The process of hiding the implementation details of a class

D) The ability of a class to expose only the relevant information to the user

Explanation:

Answer - A

Polymorphism is the ability of a single object to take on multiple forms. By using interfaces, you can create objects of different classes that implement the same interface. This enables you to write code that is more generic and can be used with different implementations of the interface.

Question 8:

What is the advantage of loose coupling between classes?

A) It makes it easier to change the implementation of a class without affecting its usage

B) It enables tight integration between classes

C) It makes it harder to change the implementation of a class without affecting its usage

D) It makes the system more modular and maintainable

Explanation:

Answer - A

When you use interfaces, you can separate the implementation of a class from its usage. This means that you can change the implementation of a class without affecting its usage. This makes your code more flexible and easier to maintain.

Question 9:

What is API design?

A) A design pattern that enables polymorphism in Java

B) A way to achieve encapsulation in Java

C) A way to provide a clear and consistent way for other developers to interact with your code

D) A way to achieve abstraction in Java

Explanation:

Answer - C

Interfaces are commonly used in API design. By defining an interface, you can provide a clear and consistent way for other developers to interact with your code. This makes it easier for them to understand and use your code. Additionally, interfaces can help to ensure that your code is more modular and maintainable, which can make it easier to add new features and fix bugs in the future.
