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

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: Ability of an object to take on many forms.

A functional interface is an interface that contains only one abstract method.

• Functional interfaces can have multiple default or static methods, but only one abstract method.

• Functional interfaces are used in lambda expressions and method references.

• Examples of functional interfaces in Java include Runnable, Callable, and Comparator.

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.

• Popular frameworks and libraries in Java include Spring, ...read more

Streams are sequences of data that allow for efficient processing of large amounts of data in a continuous manner.

• Streams are used for processing data in a continuous and efficient manner.

• They allow for reading and writing data in chunks rather than all at once.

• Examples include reading a file line by line, processing a live video feed, or receiving real-time data from a network connection.
