Enums in Java
In Java, an enum (short for enumeration) is a special type of class that represents a collection of constants (unchangeable variables, like final variables). Enums are used to define a set of named constants that are often related and can be used to ...
Java Reflection API
Java Reflection is a powerful feature that allows Java programs to inspect and manipulate objects, classes, methods, and fields dynamically at runtime. Reflection provides a way to discover information about the structure of classes and objects, even...
Object Cloning in Java
In Java, object cloning refers to the process of creating a duplicate copy of an object. This allows you to create a new object with the same state (i.e., field values) as the original object. Cloning is particularly useful in scenarios where you wan...
Java Annotations
In Java, annotations are a form of metadata that provide data about a program but do not change its behavior. Annotations offer a way to add information to Java code without affecting the code itself, making them a powerful tool for providing additio...
Inner Classes and Anonymous Classes in Java
In Java, inner classes and anonymous classes are mechanisms that allow you to define classes within other classes. These classes provide significant advantages in terms of readability, encapsulation, and flexibility in various scenarios. While both t...
Functional Programming Basics
Functional programming (FP) is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and mutable data. It focuses on writing code that is declarative, where you express what to do rather ...
Composition vs Inheritance in Java
In Java, Composition and Inheritance are two fundamental concepts used to create relationships between classes, and they each have distinct advantages and use cases. While both allow for code reuse and the creation of flexible systems, choosing betwe...
Java Streams and Lambda Expressions
Java Streams and Lambda Expressions are two powerful features introduced in Java 8 that revolutionized how developers handle data processing and function programming. They simplify the code, make it more readable, and enable powerful abstractions for...
