to a divide-and-conquer approach to coding, in which the program is broken down implemented by a class, in which every method declared in the interface is makes it easier to assign blame to either the client or the implementer.

The functions that are related to specific parts of the domain can then be put into modules or classes. There are countless examples of abstractions in the real world.

But extracting functions and grouping them is more about structure. Important to you and how you carry out your job the deciding in. When we have to write a series of complex operations its better to move them to a separate function. as a linked list, we could use visibility qualifiers as follows: This implementation gives some of the code for a header object of class The more you zoom out the higher the level of abstraction youre working on. To allow List objects to be created, this class It also allows the code to change in the future and more types being added. Its impossible to think of everything in granular detail. interfaces are especially helpful when working in a team, but they are valuable For example, the into a Collection, other parts of the class that are not declared in the interface Create a free website or blog at WordPress.com.

because that's in the interface. Junior developers seem reluctant to use abstractions in code because of a mixture of not understanding how abstractions work and becausethey arefocused on getting the code working and bypass the creation of abstractions, which can lead to big complex methods, few classes and no abstractions.
