Hello and welcome to the last post of my blog. I’ve really enjoyed writing these throughout the semester since it helped me learn more about computer science and programming in general. For this last week, I will talk about refactoring. It is one of the most important concepts to grasp in programming because it can greatly improve your code over time. Refactoring is a way of rewriting and improving code without changing the functionality of the original code. Your code may be hard to look at or understand by other programmers so you may want to refactor it to make it easier to read and understand.

Your code should be clean so you don’t end up having technical debt later on. Rushing your coding to meet deadlines will pretty much guarantee messy code and you should start refactoring early on so that the messy code does not keep piling up. When messy code keeps piling up, it becomes more of a burden to refactor and the programmer may become more unmotivated to fix it. When you refactor code, you want to make sure all your variable and method names make sense and provide some context. For example, the variable name “x” does not provide any information about what information it stores or what it is used in. Instead, your variable name should be more specific, like “accountNumber.” Having more specific variable names also helps other programmers identify what your code does exactly.

You want to start looking at refactoring at specific times during your coding process. Refactoring Guru talks about the “Rule of Three” which means when you have to code the same thing for the third time you should consider refactoring. Also consider beginning to refactor when you add a new feature because someone else’s code might be too messy to read and you need to refactor to clean it up. That also makes it easier to implement additional features later down the line. You should also consider refactoring close to the deadline of your project since it will be the last chance to make changes to the code. Your project will become open to the public and you do not want other people to see your messy code.

When you refactor, the code should become cleaner and still maintain its functionality. Sometimes you may have to completely rewrite some parts of your code in order to do this. Other times it may just be as simple as adding some spacing or renaming a variable. All your tests should still pass after refactoring. If a test fails, you messed up somewhere and made an error.

In the past, I have done some refactoring myself and I hope to continue to practice refactoring to keep my code clean, easy to understand, and easy to manage.

Hello everyone and welcome back to another week of my blog. This week I will be talking about UML diagrams. UML stands for Unified Modeling Language and it is used to model business, application structures, programming languages, analysis, design, and implementation of software-based systems. In other words, it is a way to visually represent the design and implementation of complex software. There can be many lines of codes in your software and it can be difficult to keep track of all the class relationships and hierarchies. UML diagrams can make it easier for developers to see the relationships and hierarchies. UML diagrams can work for many different programming languages. It is a standardized modeling language that any language can incorporate into the language of their choosing.

There are two different types of UML diagrams. The two different types are structural and behavioral. Structural UML diagrams show how a system is structured. They show how classes and object components work together and show the relationships between those components. Behavioral UML diagrams on the other hand, show how a system would behave from the objects interacting with each other in it. In this class I am currently taking at Worcester State University, we look at the design and structure of programs through structural UML diagrams. We went through different versions of a “DuckSimulator” and its UML diagrams to see how the program can be improved. When given a difficult concept to add to the DuckSimulator, we were able to come up with a solution through the UML diagram because we could visually see how adding interface classes would affect the DuckSimulator.

The DuckSimulator structural UML diagram we used was a class diagram intended to be written in Java. UML diagrams are very commonly used to represent software that is based on object orientated programming because they can easily show the different classes with their attributes and behaviors as well as the relationships between each class. Class diagrams are split into three vertical sections. The section at the top is the name of the class, the section in the middle are the attributes, and the section at the bottom are the methods. Types of variables and return types of methods are indicated after the name and a colon (id : int). Typically the attributes in the middle section of each class are private variables indicated by a minus sign (-) before the name. Classes can be linked together with many different arrows to show relationships between them. UML diagrams are very powerful at representing a program written with a object orientated language.
