Just as object-oriented analysis (OOA) led up to and transitioned into object-oriented design (OOD), so too does OOD lead up to and transition into object-oriented programming. Although this is not a class in programming, understanding the basic concepts and constructs of object-oriented programming (OOP) may be beneficial to an overall understanding of the object-oriented approach to systems development. Research object-oriented programming on the Web or in textbooks in order to get an overview. How are the diagrams, use cases, and other artifacts created in the object-oriented analysis and design phases used by object-oriented programming in the construction phase? Does object-oriented programming introduce any new diagrams or other constructs? What are the basic steps and processes used by OOP during the construction phase? What are some of the most popular object-oriented programming languages in use today?
