State Design Pattern
→ Behavioral Design Pattern
→ Allows an object to alter its behavior when its internal state changes.
------------------------------
Java comments:
→ Java comments are statements that are not executed by the compiler and interpreter.
→ The comments can be used to provide information about each line of code.
→ It can also be used to hide program code for specific time.
Types of Java Comments:
→ Single Line Comment:
→ The single line comment is used to comment only one line.
//This is single line comment
→ Multi Line Comment:
→ The multi line comment is used to comment multiple lines of code.
/*
This is
multi line comment
*/
→ Documentation Comment:
→ The documentation comment is used to create documentation API.
/**

documentation comment
*/
-------------
Java Inheritance:
→ Inheritance can be defined as the process where one class acquires the properties (methods and fields) of another.
→ The class which inherits the properties of other is known as subclass (derived class, child class) and the class whose properties are inherited is known as superclass (base class, parent class).
extends Keyword:
→ It is used to inherit the properties of a class.
class Parent
{
}
class Child extends Parent
{
}
Types of Inheritance:
Single Inheritance:
→ When a class extends another one class only.

{
}
Class B extends A
{
}
Multilevel Inheritance:
→ One can inherit from a derived class, thereby making this derived class the base class for the new class.

------------------------------
Strategy Design Pattern
→ It is used when there are multiple algorithms for a specific task and the client decides the actual and needed implementation.
→ Multiple solutions for a particular problem and client decides at the run time based on various criteria.
------------------------------
Null Object Design Pattern:
→ Replace “null” check.
→ Traditional method: null check for every value which has some limitations in code flow. If we follow “null object design pattern” then we can over that hurdle.
→ Default behaviour for objects which has “null” or “nothing.
→ Null object class is the default implementation.
→ It would very useful if we want some special flow for something which has nothing or null value.
→ Example: Spam classification.
------------------------------
Memento Design Pattern:
→ Restore an object to its previous state. Example: “undo” or “rollback”.
→ Basic object that is stored in different states.
→ Caretaker: Holds an ArrayList that contains all previous versions of the Memento. It can store and retrieve stored Mementos.
------------------------------
Chain of Responsibility Design Pattern:
→ Avoid coupling the sender of a request to its receiver by giving more than one receiver object a chance to handle the request.
→ Chain the receiving objects and pass the request along the chain until an object handles it.
→ It creates a chain of receiver objects for a request.
→ Each receiver contains reference to another receiver. If one receiver cannot handle the request then it will pass to the next receiver.
→ (One receiver handles a request in the chain) or (One or more receivers in the chain handles a request).
------------------------------
Interpreter Design Pattern real-time examplesRAKESH P
Interpreter Design Pattern:
→ It provides way to evaluate language grammar or expression.
→ Useful for developing domain specific languages or notations.
→ Ability to define a language’s grammar.
→ Java compiler that interprets Java source code into byte-code.
→ Defines a grammatical representation for a language and an interpreter to interpret the grammar.
→ Widely used in compilers that are implemented with an Object Oriented languages.
------------------------------
Visitor Design Pattern
→ It changes the executing algorithm of an element object.
→ Execution logic varies as the visitor varies.
→ Element object has to accept visitor object so that visitor object handles the operation on the element object.
→ Example: Supermarket products price with tax example
------------------------------
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
