Hello and welcome back to my blog! In this blog, I want to discuss YAGNI, which stands for “Ya ain’t gonna need it” or “You aren’t gonna need it.” My professor for CS-343 briefly mentioned it in class one day and I wanted to go over it more in depth. In the past, I’ve done something in my projects where I should have followed the concept of YAGNI instead. I made several methods to change a variable before I actually made the main methods of what that variable would do. In the end, it turns out the methods I made were useless toward my goal and I lost a lot of time. I hope to start applying the concept of YAGNI to my future programming in order to not waste time.

YAGNI is a really important concept in programming. Basically it means programmers and developers should only implement classes, methods, or whatever things they need only when they need them. By doing this, you can avoid doing unnecessary work and save a lot of time. When you think ahead and try to code a class or method that you think you will need in the future, it can be hard to know what exactly you need to include in it. The programmer has to do a lot of guessing and for a lot of the times, they guess incorrectly and end up not needing the feature that they spent some time on in the end. By following the concept of YAGNI instead, you don’t have to do all that guessing work and are also more focused on your current task. You should only develop things that you need once they become relevant. In a large project, YAGNI is especially beneficial for programmers and developers. Let’s say a programmer wants to design a feature they know they might need but aren’t sure if they need it or are unclear of how to implement it. By postponing the development of that feature, it can be more clear to the programmer/developer what they exactly need to do for that feature once it becomes relevant again. You should always ask yourself if the feature you are working on is really needed at the current moment. If it’s not needed, then you can take a note of it instead and come back to it later once it becomes relevant again. That way, you keep the project more simple and you program the features better since they are relevant and you have a more clear understanding of what to implement. And the most important thing, you save a lot of time with YAGNI.

Hello,

I am doing some class activities and looking over some questions ahead to save time for a thing or two. I came across the word “Behavioral Patterns” in class Act. 4 (Model 8); I got curious and looked it up. I found two articles that helped me understand the purposes, Problems with solutions, Real-World Analogy, Structure, Pseudo-code, Applicability, How to Implement, Pros and Cons, Relations with Other Patterns.

The Behavioral Patterns are concerned with providing solutions. It is about object interaction – how they communicate, how some are dependent on others, how to separate them to be both dependent and independent, and give both flexibility and testing capabilities—also, the assignment of responsibilities between objects.

The Behavioral Patterns cover many small parts to form the full extend of patterns. Like Interpreter, Template Method/Pattern, Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, and Visitor.

Interpreter

The Interpreter pattern: Evaluate any language grammar or expressions. An excellent example; this pattern would be Google Translate, which deciphers the input, and shows us the output in another language. Another example would be the Java compiler. The compiler interprets Java code and translates it into byte-code that the JVM uses to perform operations on the device it runs on. Also, it represents a great way to write simple programs that understand human-like syntax. 

Chain of Responsibility – pass requests along a chain of handlers. Upon receiving a request, each handler processes the requestor gives it to the next handler in the chain. 

Command – Turns a request into a stand-alone object that contains all information about the proposal. This transformation lets pass requests as a method arguments, delay or queue a request’s execution, and support undo-able operations. 

Iterator – traverse elements of a collection without exposing its underlying representation (list, stack, tree, etc.)

Mediator – it reduces chaotic dependencies between objects. The pattern restricts direct communications between the entities and forces them to collaborate only via a mediator object.

Memento – it saves and restores the previous state of an object without revealing the details of its implementation.

Observer – define a subscription mechanism to notify multiple objects about any events to the observed entity.

State – lets an object alter its behavior when its internal state changes. It appears as if the thing changed its class.

Strategy – define a family of algorithms, put them into a separate class, and make their objects interchangeable.

Template Method – the outline of an algorithm in the super-class but lets sub-classes revoke exact steps of the algorithm without modifying its structure.

Visitor – It separates algorithms from the objects on which they operate.
