William Swansen has worked in the employment assistance realm since 2007. He is an author, job search strategist, and career advisor who helps individuals worldwide and in various professions to find their ideal careers.
For example: "SOLID is an acronym for the first five object-oriented design principles. These are:
S - Single responsibility. A class should have only one job.
O - Open-closed. Objects should be opened for extension but closed for modification.
L - Liskov substitution. Addresses solving objects for type S, where S is a subtype of T.
I - Interface segregation. Clients shouldn't be forced to implement an interface or depend on methods they do not directly use.
D - Dependency Inversion. States that a high-level module should depend on abstractions, not on a low-level module."
