Welcome to Week 2 of our Java journey! This week dives deep into the core principles of Object-Oriented Programming (OOP) — empowering us to design, build, and manage complex software with ease.
Week 2 covers Object-Oriented Programming essentials — building blocks that let you model real-world entities, reuse code, and create robust applications.
- Understanding classes and objects
- Key OOP concepts: abstraction, encapsulation, inheritance, polymorphism
- Java constructors explained
- Difference between instance and class (static) variables
- Access control using public, private, protected modifiers
- Using the
thiskeyword effectively staticvariables and methods- The
finalkeyword and its uses - Understanding and using the
instanceofoperator
- Introduction to object modeling techniques
- Designing class diagrams for better architecture
- Inheriting properties and methods
- Using
superkeyword and method overriding - Understanding IS-A relationships
- Data hiding with encapsulation
- Defining and implementing interfaces
- Abstract classes and methods
- Polymorphism: compile-time and runtime
- Completion of Week 1: Java Basics
- JDK installed
- Familiarity with Java syntax and core concepts
- Review submitted assignments for practice
- Experiment by extending the examples and applying OOP principles
After Week 2, we'll be ready to tackle advanced Java concepts like Collections, Exception Handling, and Java I/O.
💡 Mastery of OOP lays the foundation for any serious Java developer!
