Java 17 introduced enhancements to the Pseudo-Random Number Generators (PRNGs) to make working with random numbers in Java more versatile and user-friendly. These improvements provide better support for using multiple PRNG algorithms and properly handling stream-based operations. Here’s an overview of the enhancements: 1. PRNG Enhancements: Java 17 introduces a new interface type called RandomGenerator […]

Java 17 LTS is the latest release providing long-term support for the Java SE platform. According to the Oracle No-Fee Terms and Conditions License, JDK 17 binaries are permissible for use in production and can be redistributed without any associated costs. The abbreviation “LTS” denotes “long-term support,” and this release is slated for availability on

In the Visitor pattern, we employ a visitor class to alter the execution algorithm of an element class. This flexibility allows the element’s execution algorithm to adapt as the visitor changes. This pattern falls under the behavior pattern category. In accordance with this pattern, an element object must accept the visitor object, enabling the visitor
The Template Method is a behavioral design pattern that defines a blueprint for an algorithm in a superclass but allows specific steps of the algorithm to be overridden by subclasses without changing its core structure. Consider developing a data mining application that analyzes corporate documents in various formats (PDF, DOC, CSV) to extract meaningful data.
The State Pattern is a behavioral design pattern that allows an object to alter its behavior when its internal state changes. The pattern encapsulates states as separate classes and delegates the state-specific behavior to these classes. This makes it easy to add new states and modify the behavior of an object without altering its structure.
The Memento pattern also known as Token is a behavioral design concept that enables the preservation and retrieval of an object’s prior state discreetly, without exposing the details of its internal structure and implementation. Imagine creating a text editor app with an undo feature. To save states for undo, the app records object states before
The Mediator pattern, also known as the Intermediary or Controller, helps manage communication between different objects. It stops objects from talking to each other directly and makes them talk only through a mediator. This keeps things more organized and prevents messy connections between objects. In air traffic control systems multiple aircraft need to coordinate their
The Iterator Pattern also known as Cursor is a behavioral design pattern that provides a way to access elements of an aggregate object (such as a collection) sequentially without exposing the underlying representation of that object. It is used to traverse a container of elements, allowing clients to access its elements without needing to know
The Command Pattern, alternatively referred to as the Action or Transaction pattern, belongs to the category of behavioral design patterns. It involves the conversion of a request into an independent object that encapsulates all relevant information about the request. This transformation enables the passing of requests as method arguments, facilitates the postponement or queuing of
The Chain of Responsibility pattern is a design technique where you have a series of objects, like a chain, and each object can decide whether it can handle a request or should pass it along to the next object in the chain. It’s like a relay race where each runner decides if they can carry
