Q1. What is java ?
Ans. 
Java is a high-level programming language known for its portability, security, and object-oriented features.
• Java is platform-independent, meaning it can run on any device with a Java Virtual Machine (JVM).

• It is known for its strong security features, such as automatic memory management and built-in exception handling.

• Java is an object-oriented language, allowing for modular and reusable code through classes and objects...read more

Q2. What is collection framework
Ans. 
Collection framework is a unified architecture for representing and manipulating collections of objects in Java.
• Provides interfaces (List, Set, Map) and classes (ArrayList, HashSet, HashMap) for storing and manipulating groups of objects

• Includes algorithms for searching, sorting, and manipulating collections

• Allows for easy iteration over collections using iterators or enhanced for loops

Ans. 
OOPS concepts are the four main principles of Object-Oriented Programming: Inheritance, Encapsulation, Abstraction, and Polymorphism.
• Inheritance: Allows a class to inherit properties and behavior from another class.

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

• Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.

• Polymorphism:

Q6. Java 8 feature ?
Ans. 
Java 8 introduced several new features including lambda expressions, streams, and the new Date and Time API.
• Lambda expressions allow for more concise code and easier parallel programming.

• Streams provide a way to process collections of objects in a functional style.

• The new Date and Time API offers improved date and time handling compared to the old Date and Calendar classes.
