Object-oriented design patterns for common situations

Object-oriented programming has become an integral part of modern project development. However, many popular object-oriented software frameworks and libraries frequently violate at least one of the basic object-oriented programming principles, i.e. encapsulation. This prevents creating easily maintainable and testable applications. Therefore, the main objective of the work is to develop object-oriented patterns according to object-oriented programming paradigm for several common situations, i.e. a graphical user interface (GUI), file input/output, access to remote network resources, async operations, as well as to demonstrate their usage by simple application examples. The suggested solutions were described by using Unified Modeling Language. The developed patterns are likely to open an unconventional path for the creation of easily testable and maintainable applications. The graduation work consists of 112 pages, 109 figures, 1 table and contains 44 sources.
