What are the features of the Java language?

Finally, I was asked about the features of Java. I listed several key features, including:

  • Platform Independence: Java programs can run on any device with a Java Virtual Machine (JVM), making them highly portable.
  • Object-Oriented: Java follows the OOP paradigm, which facilitates code reuse and modularity.
  • Robustness: Java’s strong memory management, exception handling, and type checking contribute to its reliability and stability.
  • Security: Java provides a secure execution environment, restricting access to system resources and ensuring safe execution of untrusted code through its security manager.
  • Multithreading: Java supports multithreading, allowing the concurrent execution of multiple threads, improving performance for complex applications.
  • Rich Standard Library: Java offers an extensive set of APIs and libraries that simplify development and provide ready-to-use functionalities.

The interview was engaging and allowed me to effectively showcase my technical knowledge and experience. It concluded with positive feedback from the interviewer and an outline of the next steps in the hiring process. Overall, it was a valuable and encouraging experience.

Regarding my preferred programming language, I stated that I favour Java. I explained that Java’s robustness, platform independence, and rich set of libraries make it a versatile language. My coursework and projects frequently involved Java, allowing me to become highly proficient and comfortable with it....

What is OOP?

The interviewer then asked, “What is OOP?” I explained that Object-Oriented Programming (OOP) is a paradigm that organizes software design around objects and classes. It allows developers to model real-world entities using attributes (fields) and behaviours (methods). OOP principles like inheritance, polymorphism, encapsulation, and abstraction promote code reuse, scalability, and maintainability....

What is abstraction?

Next, I was asked to define abstraction. I described abstraction as the concept of hiding complex implementation details and exposing only the essential features of an object. It helps developers focus on high-level operations without getting involved in the underlying complexities. In practice, abstraction is achieved through abstract classes and interfaces, which promote cleaner and more modular code....

What is encapsulation?

Following abstraction, the interviewer inquired about encapsulation. I defined encapsulation as the practice of bundling data (variables) and methods (functions) that operate on the data into a single unit, usually a class. It restricts direct access to some of an object’s components, providing controlled access through public methods. This principle helps maintain the integrity and security of the data....
