Yes, this is the end of the Java Case Study series. Part 2 is where things really start to get interesting. This episode begins as the mirror forces of traditional software development lose patience with Uncle Bob's incessant preaching and demand a practical demonstration before allowing the debate to continue. In this episode of Clean Code, Uncle Bob addresses these questions and discusses the moral and ethical elements of managing defects as a software professional. First we'll discuss Singleton and Monostate, two patterns that help you enforce the creation of only a single instance of a class. The second paragraph explicitly states that some objects require non-cohesive interfaces. But, being simple depends upon being clean.
I'll go through a little history about comp. The problem we tackle is the Payroll problem from Episode 14. I mean, you don't want to start with Part 2, because you'll miss all the preliminary discussion on the three laws. What features would it have? I've given this a lot of deep thought and this episode is the answer. Our training videos have inspired countless viewers to become the best developers they can be. We begin by talking about the overall concept of design patterns.
We reviewed this episode later and found a number of interesting discussion points, so Micah and I recorded some commentary and interspersed it along with the video. Those who just wanted to survive find themselves dogged by those who relish in the chaos, their old friends. We'll we're going to see that again. As we walk through this case study, we examine each principle in depth. Other responsibilities lie undiscovered until a change exposes them. Defects in structure are hidden from our users.
Sometimes the mirror forces agree, sometimes they are skeptical, but they cannot deny the logic. For it is those expectations that are the true motivation for Agile Software Development. What does it have in common with The Naked Gun? You'll see, in action, the project kickoff meeting. You'll see this in the video—every time we tried to add something to the test, we decided to refactor the code a bit more to make it more testable. That's what this one's all about: Component Cohesion. I love it when a plan comes together. And he answers it emphatically in the affirmative! Function Structure is about to begin! Well, actually, what emerges is a structure that our current most popular languages can't implement, because it requires multiple inheritance.
The music in your headphones? We'll also see how the discipline of Test Driven Development differs in certain larger projects, from the small Katas and examples that we've seen in the past. He kicks them out, which embarrasses and angers Tina. I guess all programmers go through periods where they just don't feel up to coding. But what value would that add? This takes three tomatoes of dependency breaking and reforming, while keeping the tests passing. Oh, you'll see some screencasts, but not in the ordinary way—not hardly.
We'll discuss the role we currently play in society, and the unwitting trust that society puts in us. Onkel Bob blander sig ikke i, hvordan du vil bruge pengene. Som et udtryk siger, så hænger pengene ikke på træerne, desværre. This time it will work, and no one will have to get nailed to anything. Is there a way to know if your functions are the right size? Others disciplines have brought their notations down from dozens to one: electronics, chemistry, biology, mathematics, etc. In fact, we'll have a surprise visit from Ward, and hear some of that history from the horse's mouth.
Do you know how much should be covered by tests? Eliminating duplication when we find it early on in our lifecycle is a good technique to master. Also get ready for some math, some logic, and a fair bit of the history of our profession. She's new and she's inexperienced, but she'll have some experienced help getting started. We'll also spend a lot of time understanding what it means for an estimate to be precise. But more importantly, we use that knowledge to solve a typical programming problem.
You can use it for everything and the opposite of everything. We'll also make the point that it is no more than that. You'll also see several design patterns and test patterns from previous episodes employed in the implementation. Security is very expensive and thus not a high priority for them in general. And, is Structured Programming really still important nowadays? So, make sure your cases are all packed and ready to go, because we're going to study those cases as we embark upon The Component Case Study! One of them has crashed; which do you hope it is? We wrote lots of unit tests, and made a load of progress.
