An Adapter pattern allows incompatible interfaces to work together, acting as a bridge. It converts the interface of one class into another interface that clients expect, enabling collaboration between classes with differing interfaces. The Adapter Pattern is also known as Wrapper. Imagine you are developing a music streaming application that plays audio files using a new […]
The singleton design pattern is used to make sure a class has just one instance, and it helps you access that instance from anywhere in your code. Imagine you’re working on a software application for a hospital. This application needs to manage patient records, appointments, and medical history. To ensure data consistency and prevent conflicts,
The Prototype pattern is a creational design pattern that focuses on creating new objects by copying an existing object, called the prototype, rather than using constructors. This pattern is particularly useful when creating objects that are similar to existing ones, as it promotes code reusability and reduces the overhead of repeatedly initializing objects from scratch.
The Builder Design pattern is a design approach that lets you create complex objects step by step. It enables producing various types and structures of an object using the same building process. Think about a complicated object that needs to be set up carefully, with many small details and parts. Usually, this setup code is

The Abstract Factory pattern is a powerful design tool that facilitates the creation of families of related objects without specifying their concrete classes. By providing an abstract interface for creating objects, this pattern enables the creation of object hierarchies with consistent structure. In Factory Method, we implemented furniture business to deliver different types furniture. Now

The Factory Method is a design pattern that provides a way to create objects without specifying their exact classes. It lets you delegate the responsibility of creating objects to subclasses, allowing for flexible and adaptable object creation. Imagine you’re developing an application for managing a furniture business. In the initial version of your app, it’s

Oracle launched Java 11 in September 2018, just six months after the previous version, Java 10. Java 11 is the first version that Oracle will support for a long time after Java 8. Oracle stopped giving support to Java 8 in January 2019. Let’s explore some of the key features and changes to the common

we will dive into practical coding examples to explore the capabilities and versatility of the Java 8 Stream API. This page will provide hands-on demonstrations of various operations that can be performed using streams, showcasing how this powerful feature simplifies complex data manipulation tasks. By following along with our examples, you’ll gain a deeper understanding

The Stream API, which was introduced with the release of Java 8, serves as a powerful tool for processing collections of objects. A stream in Java represents a sequence of objects and offers a range of methods that can be efficiently chained together to achieve specific outcomes. Key aspects of the Java stream feature include:
Java Lambda Expressions (a.k.a. lambda functions) have been a game-changer in the world of Java programming since their introduction in Java 8. These expressions provide a concise and expressive way to define anonymous functions, which are functions that don’t have a name and can be treated as values. Lambda expressions are closely related to functional
