Memory Management in Java Memory management is a crucial aspect of programming in Java, given its automatic memory management and garbage collection. This section covers the essential concepts and tools related to memory management, including garbage collection, memory leaks, profiling, and monitoring. 1. Garbage Collection Garbage collection in Java is the process of automatically reclaiming […]
Behavioral Design Patterns in Java Behavioral design patterns focus on communication between objects, how they interact and fulfill their responsibilities. These patterns help define how objects should communicate and cooperate. Let’s deep dive into the Observer, Strategy, Command, and Template Method patterns. 1. Observer Pattern The Observer pattern defines a one-to-many dependency between objects so
Structural Design Patterns in Java Structural design patterns deal with object composition and relationships, allowing us to compose objects to form larger structures and relationships between them. In this discussion, we’ll cover four structural patterns: Adapter, Decorator, Proxy, and Composite. 1. Adapter Pattern The Adapter pattern allows incompatible interfaces to work together. It acts as
Design Patterns in Java: Creational Patterns Design patterns are general reusable solutions to common problems in software design. Creational patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. In this discussion, we’ll cover four creational patterns: Singleton, Factory, Builder, and Facade. 1. Singleton Pattern The Singleton pattern
ORM with Hibernate Object-Relational Mapping (ORM) is a technique for converting data between incompatible systems using object-oriented programming languages. Hibernate is a popular ORM framework for Java that simplifies database interactions by mapping Java objects to database tables. Key Concepts in Hibernate Setting Up Hibernate 1. Add Hibernate Dependencies To use Hibernate, you need to
Java Database Connectivity (JDBC) Java Database Connectivity (JDBC) is an API that enables Java applications to interact with a wide range of databases. It provides methods for querying and updating data in a database. JDBC is part of the Java Standard Edition platform and is included in the java.sql package. Key Concepts in JDBC Setting
Building Simple Web Servers in Java Building a web server in Java is a great way to understand the basics of HTTP and server-client communication. Java provides several ways to create web servers, from basic implementations using sockets to more advanced frameworks like Jetty and Spring Boot. This guide will cover: 1. Basic HTTP Server
Streams and Lambda Expressions in Java Java 8 introduced Streams and Lambda expressions, revolutionizing the way we handle collections and other data processing tasks by bringing functional programming concepts to Java. Introduction to Functional Programming Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and
Asynchronous Programming in Java: Futures and CompletableFutures Asynchronous programming is a programming paradigm that allows tasks to be executed in the background without blocking the main thread. In Java, asynchronous programming can be achieved using Futures and CompletableFutures. Futures in Java The Future interface represents the result of an asynchronous computation. It provides methods to
Inner Classes in Java Inner classes in Java are classes defined within the scope of another class. They provide a powerful way to logically group classes that are only used in one place, increase encapsulation, and can lead to more readable and maintainable code. There are four types of inner classes in Java: member inner
