Yes, It's Never too late to learn Web Development

Yesterday, I was speaking to one of my friend who was not from the programming background but working as a teacher in a college of Engineering and Technology in the countryside of India. He just turned 40 and he is also the father of two wonderful kids. He has been teaching Maths to B.Tech students on a private engineer college for the last 15 years. He is earning Ok but he always wanted to explore the world and he now realizes that a Programming job can provide him that opportunity, so he contacted me to find out whether it's too late for a Programming career.  He is keen to learn Web development, particularly using latest technologies like Angular, React, Vue.js, and Node.js but he is worried that it might be just too late for him to become a Web developer or work in a software development company.

The @SpringBootApplication annotation Example in Java + Spring Boot

Hello guys, today, we'll learn about the @SpringBootApplication annotation, one of the most important annotations from popular Spring Boot framework, which has changed the way Java developers use Spring framework for writing Java applications. In this article, I'll explain to you the meaning of @SpringBootApplication and it's used in a simple Spring Boot application. We use @SpringBootApplication annotation on our Application or Main class to enable a host of features e.g. Java-based Spring configuration, component scanning, and in particular for enabling Spring Boot's auto-configuration feature.

Top 5 Best Java 8 Tutorials, Courses, and Books

It's been quite some time since the Java 8 was released but Java community is still buzzing with functional programming and lambda expression. Many developers, programmers, and bloggers have already shared lots of really good tutorial to learn lambda expressions, probably the biggest thing in Java world after Generic was introduced in Java 5. While the term "lambda expression" may sound abstract and academic, Java 8 Lambdas can have a big impact on how you program every day. Java 8 has not only introduced Lambda expressions but also Stream API, Functional interfaces, new Date and Time API and default methods, which has completely changed the way you write your Java code. As a professional Java developer, you will have to learn Java 8 one day, and it's better to do sooner than later.

Difference between @ContextConfiguration and @SpringApplicationConfiguration in Spring Boot Integration Test

Even though both @ContextConfiguration and @SpringApplicationConfiguration annotations are used along with SpringJUnit4ClassRunner to specify how to load the Spring application context, there is a subtle difference between them. Although @ContextConfiguration does a great job in loading application context it doesn't take full advantage of Spring Boot features. Spring Boot applications are ultimately loaded by either SpringApplication ( in case of the JAR) or SpringBootServletInitializer. This class not only loads the application context but also enables logging and loading of external properties specified in application.properties or application.yml file, and other features of Spring Boot framework, which is not loaded or enabled by the @ContextConfiguration annotation.

Differences between @RequestParam and @PathVariable annotations in Spring MVC?

The Spring MVC framework, one of the most popular frameworks for developing a web application in Java world also provides several useful annotations to extract data from the incoming request and mapping the request to controller e.g. @RequestMapping, @RequestParam, and @PathVariable. Even though both @RequestParam and @ParthVariable is used to extract values from the HTTP request, there is a subtle difference between them, which makes them a useful question from an interview and spring certification point of view. We'll examine the subtle difference between @RequestParam and @PathVaraible in this article. As the name suggests @RequestParam is used to get the request parameters from URL, also known as query parameters, while @PathVariable extracts values from URI.
