The Attack method in BotanicRepeater retrieves a bullet via the mediater: @Override public void attack(ICharacter target) { Bullet projectile = Mediator.getInstance().fetchBullet("SingleBullet", launchPoint, new Point(1300, launchPoint.y)); } In BotanicRepeaterFactory, create a plant character using the factory method: @Override ...

Behavioral Patterns Strategy Pattern Defines a family of algorithms, encapsulates each, and makes them interchangeable. Context uses a Strategy object to vary its behavior. Roles: Strategy: Interface declaring algorithm methods ConcreteStrategy: Implements specific algorithm Context: Maintains strategy reference Example: E-comerce Discounts i ...

Visitor Pattern The Visitor Pattern is a behavioral design pattern that allows you to add new operations to existing object structures without modifying the structures themselves. This pattern is particularly useful when you need to perform various operations on a collection of objects that have different interfaces. The key components of the ...

In software development, there's a common philosophy: many problems can be solved by adding an intermediate layer. The Proxy pattern is a direct application of this concept. The Proxy pattern is defined as: **Provide a surrogate or placeholder for another object to control access to it.** This involves delegating a class to another class that ...

IOC Section 1. Spring Ecosystem Overview Spring is a comprehensive ecosystem providing essential infrastructure for Java application development. The Spring ecosystem typically consists of: Spring Framework - the core framework Spring Boot - adds auto-configuration capability, which reads Spring Boot Starter configuration during startup, initi ...

In software architecture, cross-cutting concerns such as logging, security checks, and transaction management often need to be applied across multiple components. A naive approach involves manually inserting logic into every business method, leading to code duplication and tight coupling. For instance, if we need to audit execution before and a ...

Inversion of Control and Dependency Injection Inversion of Control (IoC) functions as an architectural principle rather than a concrete implementation pattern. Its primary objective is to decouple object creation and dependency resolution from business logic by delegating these responsibilities to a dedicated container. Dependency Injection (DI ...

Design patterns are typical solutions to common problems in software design. They represent best practices used by experienced object-oriented software developers. Categories of Design Patterns Creational Patterns These patterns abstract the instantiation process, focusing on how objects are created in a flexible and reusable manner. Factory M ...

The Single Responsibility Principle states that a class should have only one reason to change. This means each class or interface should focus on a single functionality. Problem Scenario: If a class handles multiple responsibilities, modifying one responsibility might inadvertently affect the other, increasing the risk of bugs. Key Benefits: R ...

The human-array computer is undoubtedly one of the most stunning scenes in The Three-Body Problem. In the novel, "von Neumann" organized three soldiers into each gate component, ultimately mobilizing thirty million soldiers of "the First Emperor" to form a colossal computer of ten million gate parts, all in an attempt to sol ...
