![]() ![]() Just keep in mind that Java 8 was a huge improvement both performance and security-wise, and you should be good to go. This is probably going to be one of the main Java 8 interview questions that you’ll receive. Overall, Java 8 made the programming language more accessible and better in-line with modern-day programming languages. Java 8 introduced language support for String, provided an improved Date/Time API, and furthered the development of JVM - the system responsible for many things Java, including its security. This update to the programming language was one of the more notable ones - it would be beneficial to know what new features emerged from it. In your Java interview questions, you are more than likely to get mostly comparison-type ones. Because of the “ WORA” principle which Java is built on, it can be transferred and applied on to any machine you'd like - it's fully flexible and multifunctional. This is because of an interpreter called JVM - this interpreter is installed together with Java itself, and it constantly supplies your computer with the latest security updates from the internet.Īdditionally, Java is fully portable. Java is also considered to be very secure when compared to other programming languages. ![]() Java is considered to be quite easy to learn and master, especially when compared with other programming languages out there. Question 3: Name a few notable Java features.įor beginner programmers and developers, the most important feature is simplicity. Java uses some data types ( char, byte, float) which are not objects. This is a quite possible to be one of Java interview questions and no, it is not fully object-orientated. Question 2: Is Java fully object-orientated? It is known for being flexible and running with high-performance. Java is designed to represent the “ WORA” slogan - “ write once, run anywhere”. It was created and developed back in 1991 by a man named James Gosling. Java is an object-orientated, high-level secure programming language. It seems like a pretty simple question, doesn’t it? Well, your potential employer probably expects a clear and straight-to-the-point answer, so let’s provide him one. Have you ever wondered which online learning platforms are the best for your career?
