Problem Statement\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eAs C# exercises grow, repeated logic can appear across several classes and methods. Learners may copy similar code into different sections because they are unsure how to create a shared structure. This repetition makes code harder to review, adjust, and explain. Class responsibilities may also overlap, causing data handling, calculations, and validation to become mixed together. A more organized approach is needed to create reusable components while keeping each part understandable.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003e2. Solution\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eEcho Framework introduces methods for identifying repeated patterns and placing shared logic into suitable structures. Learners examine how interfaces, inheritance, composition, and reusable methods can support organized code. Each topic is introduced through small examples before being used in broader exercises. Planning tasks help learners decide which responsibilities belong together and which should remain separate. Code review activities encourage careful naming, focused classes, and readable relationships.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003e3. What’s Inside\u003c\/span\u003e\u003c\/h2\u003e\n\u003ch3\u003e\u003cspan\u003eModule 1: Recognizing Repeated Patterns\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe opening module explains how to identify code that performs similar work in several places. Learners compare repeated methods, duplicated conditions, and related data structures. Exercises focus on describing the shared purpose before changing the code.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 2: Reusable Methods and Helper Classes\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis module examines how shared calculations, formatting rules, and validation checks can be placed into focused methods or helper classes. Learners review method signatures, returned values, parameter choices, and naming. Practice tasks involve reorganizing repeated instructions into reusable sections.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 3: Composition Between Classes\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eLearners study how one class can contain or coordinate other objects. Examples include records with contact details, catalogs with entries, and schedules with grouped items. The module explains how composition can represent clear relationships without placing every responsibility inside one class.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 4: Introductory Inheritance\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis section introduces parent and child class relationships. Learners examine shared properties, inherited methods, and specialized behavior. Exercises compare situations where inheritance is suitable with cases where composition creates a clearer structure.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 5: Interfaces and Shared Behaviour\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eLearners explore interfaces as descriptions of common actions. Guided examples show how different classes can follow the same method structure while providing their own implementation. Activities include creating simple reporting, formatting, and calculation behaviours.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 6: Polymorphic Method Calls\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis module explains how objects with a shared interface or parent type can be handled through one coordinated process. Learners work with grouped objects and observe how each object responds according to its own implementation.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 7: Separating Responsibilities\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eLearners examine classes that contain too many unrelated tasks. They practise dividing storage, validation, calculation, and presentation logic into focused components. Review questions help identify unclear boundaries and unnecessary dependencies.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 8: Error Handling Foundations\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis section introduces structured handling of unexpected values and interrupted operations. Learners examine guarded code blocks, informative messages, and sensible recovery paths. Exercises focus on keeping error handling separate from the central task.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eModule 9: Framework Planning Exercise\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe concluding exercise asks learners to design a small class system from a written scenario. They define responsibilities, relationships, shared behaviours, and reusable components before writing the code. The task concludes with a structured review of naming, repetition, and class boundaries.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eIncluded Learning Materials\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eEcho Framework includes written modules, code examples, planning worksheets, guided refactoring tasks, terminology notes, review questions, and a concluding design exercise.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003e4.
