As the scale of computation and complexity in your programs increases, it will become more difficult to reason about the behavior of the system without looking at it from a more abstract point-of-view. Object-Oriented Programming provides rules and techniques that can reliably allow you to reason about the behavior of complex programs by logically encapsulating their components in "objects". ![[DALLE3_ObjectOrientedProgramming.png]] ## Concept Tree ### Basics 1. **Classes and Objects** - Introduction to Classes and Objects - Creating Classes - Instantiating Objects - Constructors 2. **Inheritance** - Base and Derived Classes - Overriding Methods 3. **Encapsulation** - Access Modifiers - Getters and Setters 4. **Polymorphism** - Method Overloading - Method Overriding 5. **Writing Simple Object-Oriented Programs** - Implementing Class Hierarchies - Basic OOP Projects and Exercises ### More Advanced 1. **Abstract Classes** - Defining Abstract Classes - Abstract Methods 2. **Interfaces** - Implementing Interfaces - Multiple Interface Inheritance 3. **Exception Handling** - Try-Catch Blocks - Custom Exceptions 4. **Additional OOP Concepts** - Composition - Delegation - Dependency Injection ### Mastery 1. **Multi-Threading** - Introduction to Threads - Creating and Managing Threads - Synchronization 2. **Generics** - Generic Classes - Generic Methods - Constraints and Wildcards 3. **Design Patterns in OOP** - Singleton Pattern - Factory Pattern - Observer Pattern - Strategy Pattern - Others (e.g., Command, Decorator) 4. **Advanced OOP Projects and Exercises** - Complex OOP-Based Applications - Performance Considerations
