Kellogg Brown and Root Auto CAD Engineer Interview Questions and Answers

Java OOPs concepts are used in automation framework design for better code organization and reusability.

• Encapsulation: Used to hide the internal implementation details of classes and provide access through methods.

• Inheritance: Allows for code reuse by creating parent-child relationships between classes.

• Polymorphism: Enables methods to behave differently based on the object they are called on.

• Abstraction: Helps in defin...read more

An interface in software development is a contract that defines the methods that a class must implement.

• Interfaces in programming languages like Java, C#, and TypeScript provide a way to achieve abstraction and multiple inheritance.

• Classes implementing an interface must provide concrete implementations for all the methods defined in the interface.

• Interfaces allow for loose coupling between components, making code more
