Middle Course

This level bridges foundational OOP with practical structure to move confidently toward advanced topics. You’ll work through interfaces and abstract classes, designing hierarchies without duplicated logic. We’ll go deeper into Java collections: List, Set, Map, iterators, and object comparison. The intro to generics explains parameterized types and bounds. You’ll start handling files—read/write, character encodings, and I/O error handling. There is a section on unit testing with JUnit and logging (SLF4J/Logback) for diagnostics. The final mini-project is a console app organized into packages with a clear folder layout (Maven/Gradle).
