OOP Concepts for Java Technical Interviews
This course is a focused sweep through the object-oriented programming concepts that come up repeatedly in Java interviews — from source file structure and class-level modifiers through to abstraction, encapsulation, inheritance, and polymorphism. It's built around interview readiness rather than general Java development.
Who It's For
Java developers preparing for technical interviews who already have basic Java syntax knowledge and want to solidify their grasp of OOP fundamentals before being tested on them.
Key Takeaways
- Core OOP pillars: abstraction, encapsulation, inheritance, and polymorphism
- The distinction between method overloading, overriding, and hiding
- Interfaces, abstract classes, and abstract methods
- Constructors, object typecasting, and method signatures
A dense, checklist-style course best used as targeted interview prep rather than a first introduction to Java.
