One of the frequently asked Spring MVC Interview questions is about explaining the flow of web request i.e. how an HTTP request is processed from start to end. In other words, explaining the flow of request in Spring MVC. Since many of my readers ask this question time and again, I thought to summarize the flow of request processing in a short article. It all starts with the client, which sends a request to a specific URL. When that request hit the web container e.g. Tomcat it look into web.xml and find the Servlet or Filter which is mapped to that particular URL. It the delegate that Servlet or Filter to process the request. Since Spring MVC is built on top of Servlet, this is also the initial flow of request in any Spring MVC based Java web application. Remember, Web container e.g. Tomcat is responsible for creating Servlet and Filter instances and invoking their various life-cycle methods e.g. init(), service(), destroy(). In the case of HTTP request, HttpServlet handles that a...

You can program in Java (or are learning to.) That's great! But what else can you do with those skills? Are you trapped with Java? Not at all. One of the reasons I chose Java as a language for use in the classroom is that Java programming skills translate so well into skills for other languages. Here are some other languages, and a brief look at what your Java programming skills will give you in the way of a head start, and what differences to look out for. C# (C Sharp) C# and Java are practically the same. C#'s roots are in Java, as is the concept of its libraries relative to Java's API. The libraries differ, but if you're used to Java's API you'll have no trouble getting right into C#'s libraries to find the classes you're looking for. The major development tools are very similar, or, in many cases, you can use the same IDEs for C# as for Java. You can also do cross-platform development in C# just as you can with Java thanks to tools like Mo...

Java Interviews are a little bit different than traditional programming interviews on tech giants and product based companies like Google, Amazon, Microsoft, or Facebook. First, even though it has questions from Data Structure and Algorithms like String or Array, you can still manage to clear Java interviews if you are not an expert on them. The questions are a little bit easier and more practical than those companies. Another very important thing about Java interviews are questions based upon Java programming language and JDK API. Since Java is also an Object-oriented programming language, you will find lots of OOP questions there. Since Java is primarily used as an application programming language, the focus is aligned accordingly with questions mostly focusing on API, Java concepts, and design patterns. Also, Java interviews change a lot depending upon the candidate's experience. For example, junior developers with 1 to 2 or 3 to 4 years of experience will see more questi...
