How to use Deque Data Structure in Java? Example Tutorial

Hello friends, I am really glad to see you all again here. And I know you are here to learn new and valuable Java concepts and continue your journey on Java. Today we are gonna learn something that is really important logically. yes! you heard right, we are going to learn about Deque data structure in Java and how to use Deque in the Java program. Deque is a special data structure, a double-ended queue that allows you to process elements at both ends, I mean you can add and remove objects from both front and rear end. It's a short form of Double-Ended Queue and pronounced as "Deck".  

Top 30 Stack and Queue Data Structure Interview Questions for Practice

Hello guys, stack and queue are two fundamental data structures which are used on many applications and algorithms. For example, you can use stack to convert a recursive algorithm to iterative one, which is more safe in production and no risk of StackOverFlowError. Similarly, queue is used in many asynchronous algorithms like producer consumer pattern or publish subscribe pattern to exchange messages. Because of that, they are also quite popular on coding interviews, particularly on Java developer interviews. In the past, I have shared 100+ data structure questions as well as String coding problems, array questions, linkedlist questions, recursion questions and even dynamic programming questions but I have not shared stack and queue related questions before. 

Difference between Queue and Deque in Java? Example Tutorial

Hello guys, today I am going to share another interesting question from Java interview, what is difference between Queue and Deque in Java. This question was asked to one of my reader in a recent interview with JP Morgan Mumbai and this is also a popular Java collection interview question. While he was able to answer the question, he wasn't able to convince interviewer so he asked me how to answer this question. So I am writing this post to share my answer on Queue vs Deque in Java. In the vast world of Java programming, the need to manage data efficiently often leads developers to specialized data structures.
