🕰️🔒 Singleton Pattern: A stalwart in DP, this ensures that a class has only one instance and provides a global point of access to it. It's a go-to solution for scenarios where having a single, shared instance is crucial for controlling access, managing resources. #Java101 🧵👇

Un Stream es una implementación en memoria de map / filter / reduce. #java #java101 #jvmadvent #javaadvent #jvm
📜 Interpreter Pattern: This pattern defines a grammar for interpreting a language and provides an interface to evaluate statements in that language. Perfect for building interpreters and evaluators for expressions. #InterpreterPattern #Programming #Java101 #java 🧵👇
⚔️ Command Pattern: This pattern encapsulates a request as an object, allowing clients to be parameterized with different requests, queued, and support reversible operations. A powerful warrior for decoupling senders and receivers. #DesignPatterns #CommandPattern #Java101 🧵👇
📜In this example, NumberExpression represents individual numbers, and AdditionExpression represents the addition of two expressions. You can imagine how this pattern could be extended to interpret more complex expressions. #InterpreterPattern #Programming #Java101 #java #Coding
Las cadenas de caracteres se representan en Java mediante la clase String. #jvm #java101 #jvmadvent #java
🔗🌟 Chain of Responsibility Pattern: Empowers objects to handle requests without knowing the exact recipient. Each link in the chain decides to process the request or pass it to the next, fostering a flexible and decoupled structure. #ChainOfResponsibility #Java101 #Java
Aprenda a utilizar la instanciación lazy y la instanciación eager en sus programas Java. ¿Qué método es mejor? Depende del escenario. #java #java101 #jvmadvent #javaadvent
¿Cuáles son los Principios SOLID? SOLID es un acrónimo que agrupa 5 principios clave para el desarrollo eficiente, replicable, mantenible y escalable de software. #java #java101 #jvmadvent #javaadvent #AdventOfCode
⚙️ Concept: The pattern involves a class with a private constructor, a static method for accessing the single instance, and a private static instance variable. It guarantees that only one instance is created and offers a central access point to that instance. #Java #Java101
✨ Concept: Decouples senders and receivers, allowing multiple objects to respond to requests without direct coupling. #DesignPatterns #ChainOfResponsibility #Java101 #Programming #Java
🌐 Importance: Offers flexibility and scalability to the system, making it easy to add new request handlers without modifying existing code. #DesignPatterns #ChainOfResponsibility #Java101 #Programming #Java
🌍 Scenario: Imagine an expense approval system with different hierarchical levels, where each level decides to approve or pass the request to the next. #DesignPatterns #ChainOfResponsibility #Java101 #Programming #Java
🌐 Importance: Singleton Pattern is pivotal for scenarios like managing configurations, logging, or database connections. It ensures consistency and prevents unnecessary resource consumption by maintaining a single, shared instance throughout the application. #Java #Java101
🔄 Use Case: When an employee requests an expense, the corresponding object in the chain evaluates whether to approve it or pass the request to the next level. Unleash the power of chained responsibility for elegant request handling! #Java101 #Programming #Java
