Java Collections Framework Quiz for Developers

Today, we’ve come up with a mind-boggling Java collections framework quiz featured with 25 best questions to help you learning the concept of Java collections. The Java collections framework (JCF) is a system of classes and interfaces that implement reusable collection data structures like list, set and hashmaps etc. Just for your information, we must tell you that Java collection is the most frequently asked topic in any Java interview so the quiz would help you a lot to get prepared. And that’s the reason we’ve ramped up this quiz for both software developers and test engineers so that they can assess their Java programming skills.

Another important aspect to come out with such a quiz was to train our readers on the topic of  Java collections. So that they get to know all the important facts about the Java collections. Hence, we’ve given our best to add all the relevant collections centric questions in this quiz to make it as meaningful as it could be. Also, we’ve extended the quiz with 25 questions and it’s now a bit more than the usual size of our earlier quizzes. 🙂

Let’s now end today’s talk with a famous quote from the geek of the geeks, the Linus Torvalds who was the key man behind the development of the Linux.

“Most good programmers do programming not because they expect to get paid or get adulation by the public, but because it is fun to program.”

All the Best!
