REST has now become a standard way to develop web services and when it comes to Java, there are many frameworks and libraries available like JAX-RS, Restlet, Jersey, RESTEasy, Apache CFX, etc, but I encourage Java developers to use Spring framework to develop RESTful web services. But, some of you might ask, why use Spring Framework to develop RESTful web services in Java? What is the advantage and why it's better than other frameworks and libraries available out there? Well, the most important reason I think to use Spring for developing RESTful web service is that you can use your Spring MVC experience to develop RESTful web services.

10 Examples of JdbcTemplate in Spring Framework for Java Programmers

Hello Java programmers, If you have been using the Spring framework then you may know that the JdbcTempalte is one of the most useful classes of the Spring framework. The JdbcTempalte class provides lots of convenient methods for performing database-related tasks that take the pain away from using the JDBC API. If you have worked in any real-life JAva project which connects to a Database using JDBC then you know that JDBC API is not very convenient to use as it requires a lot of boilerplate code. For example, to execute a simple SELECT query, you first need to create a Connection and Statement object to execute the query and iterate through a ResultSet Object to get the result of the query. Finally, you need to close all of these resources to prevent resource leaks in Java.

How Spring MVC Framework works? How HTTP Request is processed?

One of the frequently asked Spring MVC Interview questions is about explaining the flow of web requests i.e. how an HTTP request is processed from start to end. In other words, explaining the flow of requests 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 hits the web container like Tomcat it looks into web.xml and finds 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 requests in any Spring MVC based Java web application.

3 Ways to Learn Spring Core, Spring MVC, Spring Security, and Spring Boot Framework

If you are a Java developer and want to learn the Spring framework then you have come to the right place. In this article, I will share three ways to learn the Spring framework, but before that let's understand what is a spring framework and why Java developers should learn Spring framework? Well, Spring is a framework that assists you to develop Java applications by following some best practices, particularly the principle of dependency injection and inversion of control. As per this principle, instead of the class asking for its dependency, the framework provides them at runtime.  Following these principles improves your code quality because it reduces coupling between different parts of your applications like between modules and classes, which makes it easier to test and develop.

Java HashMap ContainsKey and ContainsValue Example

Hello guys, one of the common problems many Java developers working with HashMap face is how to check if the Map contains a particular key or value? You can use this to check duplicate keys or just to ensure that you are not overriding the current value because if you insert a key that already exists in the HashMap, then you end up overriding its value. Since HashMap also allows duplicate values, it's also possible that the same value may be paired against multiple keys, so just removing a mapping may not be enough to remove that particular value. Not paying attention to these details has actually caused issues in the Java applications.

How to Create a thread-safe ConcurrentHashSet in Java 8? [Example]

Until JDK 8, there was no way to create a large, thread-safe, ConcurrentHashSet in Java. The java.util.concurrent package doesn't even have a class called ConcurrentHashSet, but from JDK 8 onwards, you can use the newly added keySet(default value) and newKeySet() methods to create a ConcurrentHashSet backed by ConcurrentHashMap in Java. This is better than old tactical solutions like using a concurrent hash map with dummy value or using the set view of the map, where you cannot add new elements. The Set returned by keySet(defaultValue) and newKeySet() methods of JDK 8 is a proper set, where you can also add new elements along with performing other set operations like contains(), remove() etc.

Top 20 Libraries and APIs Java Developer should Learn [UPDATED]

One of the traits of a good and experienced Java developer is the extensive knowledge of API, including JDK and third-party libraries. I spent a good deal of time learning API, especially after reading Effective Java 3rd Edition, where Joshua Bloch has advised us to use existing API for development rather than writing new pieces of code for common stuff. That advice making sense to me because of the testing exposure these 2nd party libraries get. In this article, I am going to share some of the most useful and essential libraries and APIs, a Java developer should be familiar with. Btw, I am not including frameworks like Spring and Hibernate because they are pretty well known and have specific features.

Top 10 Java ConcurrentHashMap Interview Questions with Answers [UPDATED]

The ConcurrentHashMap class part of concurrent collections package added on JDK 1.5 which contains utility classes like BlockingQueue, CopyOnWriteArrayList, CopyOnWriteArraySet etc. It is a replacement of synchronized hash-based map implementations e.g. Hashtable and synchronized HashMap. It implements Map and ConcurrentMap (a sub-interface of Map) interface which allows you to store key-value pairs. The class is similar to HashMap or Hashtable but it's more scalable and the right fit for concurrent Java application. Unlike Hashtable which achieves its thread-safety by compromising the scalability, ConcurrentHashMap uses advanced techniques e.g. dividing the map into segments to remain thread-safe and scalable at the same time.

Java 9 Factory Methods for Collections Example - Creating Unmodifiable List, Set, and Map

Hello guys, this is my first article in Java 9 features on this blog, and today you'll learn about my favorite feature "factory methods for collection", which is introduced as part of JEP 269. The JEP stands for the JDK enhancement proposal. If you have worked in Groovy or Kotlin then you know that how easy is to create the list with elements using collection literals e.g. to create a list of 1, 2, 3 you can simply write val items = listOf(1, 2, 3). Unfortunately, Java doesn't support that yet but things have been improved with the factory methods for collection in JDK 9 and it's almost like that. JDK has added static factory methods like of() on to basic Collection interfaces which you can use to create a list of items.
