Top 5 Spring Cloud Annotations for Cloud Native Java Applications

If you are developing a Java application for Cloud, then you should learn Spring Cloud, a great framework and extension of the popular Spring framework, which can help you to develop a cloud-native Java application.

Top 100 Data Structure and Algorithm Interview Questions for Java Programmers

Data structure and algorithms are a core part of any Programming job interview. It doesn't matter whether you are a C++ developer, a Java developer or a Web developer working in JavaScript, Angular, React, or Query. As a computer science graduate, it's expected from a program to have strong knowledge of both basic data structures, e.g. array, linked list, binary tree, hash table, stack, queue, and advanced data structures like the binary heap, trie, self-balanced tree, circular buffer, etc. I have taken a lot of Java interviews for both junior and senior positions in the past, and I have also been involved in interviewing C++ developers. One difference that I have clearly noticed between a C++ and a Java developer is their understanding and command of Data structure and algorithms.

Hibernate is the leading ORM (Object to relational) framework in Java world used to implement the persistence layer of enterprise Java applications.
