DXC Technology Associate Professional Software Engineer Interview Questions and Answers

Java supports key features of OOP like inheritance, encapsulation, polymorphism, and abstraction.

• Inheritance allows a class to inherit properties and behavior from another class.

• Encapsulation hides the internal state of an object and restricts access to it.

• Polymorphism allows objects to be treated as instances of their parent class.

• Abstraction hides the implementation details and only shows the necessary features.

OOPS (Object-Oriented Programming) features include encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (class).

• Inheritance: Ability to create a new class that inherits attributes and methods from an existing class.

• Polymorphism: Ability to use a single interface to represent different data types or objects.

• Abstraction: Hidin...read more
