This article goes over some of the more essential element from Robert Martin's book Clean Code, including meaningful names and multiple. Agile Java™: Crafting Code with Test-Driven Development Robert C. Martin and Micah Martin Clean Code: A Handbook of Agile Software Craftsmanship. There are two things- Programming and Good Programming. Programming is what we have all been doing. Now is the time to do good.

In the case of objects, it is easy to add new objects but harder to add new behavior.
Let's understand this through an example: As you can see, if I want to add a new type of shape, say for example, rhombus, I can simply add its class extending Shape trait and provide the implementation for the area method. That's all I need to do.
But its hard to add new behavior. If suppose I need to a new method say volume. Then all the subclasses extending this trait need to change.
Now consider data structures example: In this, if I need to add new behavior, say, volume, then I can easily add that without making any trouble and provide implementations for the different shapes. But in case Clean code robert c martin need to add new shape new objectI need to add its implementation in all the methods of the Geometry class.

Procedural code code using data structures makes it easy to add new functions without changing the existing data structures. OO code, on the other hand, makes clean code robert c martin easy to add new classes without changing existing functions. In any complex system, there are going to be times when we want to add new data types rather than new functions.
For these cases, objects and OO are most appropriate. On the other hand, there will also be times when we'll want to add new functions as opposed to data types. In that case, procedural code and data structures will be more appropriate.

In short, the Law of Demeter aims to keep you from doing things like this: Error handling is just one of those things that we all have to do when we program. Input can be abnormal and devices can fail.
In short, things can go wrong, and when they do, we as programmers are responsible for making sure that our code does what it needs to do. If you throw a checked exception from a method in your code and clean code robert c martin catch is three levels above, you must declare that exception in the signature of each method between you and the catch.
When I read source code, certain parts are rendered in specific ways that make it easier to pull the information into my brain.
