Java and Object-Oriented Programming for Technical Interviews

Many candidates can write code but struggle to explain the logic and architecture behind their choices during a high-pressure technical interview. This course bridges that gap by helping you move beyond basic syntax to a place where you can confidently discuss how Java works and why specific design patterns matter. You will transform from a programmer who follows instructions into an engineer who can justify their technical decisions. What you'll learn: - Understand core Java terminology and foundational language structures - Apply fundamental OOP principles including inheritance, polymorphism, and encapsulation - Explain memory management and how the JVM handles objects under the hood - Master modern Java features such as local variable type inference and streamlined collection APIs - Practice articulating complex design patterns and their real-world applications - Analyze the trade-offs between different data structures and their performance implications - Learn basic unit testing principles with modern frameworks to verify code logic The course begins with essential definitions and the basic building blocks of the language before moving into the deeper mechanics of object-oriented design and interview-style communication. It is designed for beginners and aspiring software engineers who want to build a professional vocabulary alongside their coding skills. Start building a solid foundation in Java and OOP to excel in your next technical conversation.
