3 Best Practices Java Programmers Can Learn From Spring Framework

There is no doubt that Spring Framework is one of the most popular Java frameworks and makes it really easy to create real-world, enterprise-grade Java applications easy by providing features like dependency injection and inversion of control. But, to be honest, Spring is much more than just another DI and IOC framework. It goes one more level to simplify many of Java APIs e.g. JDBC, JMS, Java Mail etc by providing a useful layer of abstraction. It's much more easy to work with JDBC with Spring's JdbcTempalte and other utility class. They remove most of the friction Java developer faces with respect to executing SQL statement and processing ResultSet to get the Java object they want.

Top 5 Free Git Courses for Programmers to Learn Online - Best of Lot

One of my goals in 2018 is to learn and master Git and I have been searching some good tutorials and courses to start with. The Internet is full of git tutorials and a simple Google search will leave you thousands of tutorials but the big question mark is where do you start? It's easy to pick a tutorial or a blog post if you have some background about what is Git, what it does? and how to use it but if you don't have much background then you need a course which can tell you all the information from the ground up. I personally like learning from a book or an online course before moving to blog posts as they were often well structured. When you search for Git courses in popular online course websites e.g. Udemy, Pluralsight or Coursera, you will find some good courses e.g. Git Complete: The Definitive Guide on Udemy and Git Fundamentals from Pluralsight which will teach you everything about Git step by step. These are excellent resources to start with Git.

Top 5 Hibernate and JPA Courses for Java Developers to Learn Online

Hibernate is one of the essential frameworks for Java and Java EE or JEE programmers, especially if you are working on the server side of a Java web development project. It's an ORM tool or a framework which allows you to deal with only objects while Hibernate takes care of your data on your behalf. For example, instead of writing classes with SQL to load, save, and update data using DAO design pattern, you can simply use Hibernate framework in your project. It will allow you to deal with just objects while it will load, save, and update data in the background. Instead of you loading and saving data to/from the database and then populating objects, Hibernate just give you a readymade object and also takes care of updating data when the state of object changes. Btw, this is just one benefit of using Hibernate, another one is that it provides inbuilt caching.

Difference between @Component, @Service, @Controller, and @Repository in Spring

Before you learn the difference between @Component, @Service, @Controller, and @Repository annotations in Spring framework, it's important to understand the role of @Component annotation in Spring. During initial release of Spring, all beans are used to be declared in an XML file. For a large project, this quickly becomes a massive task and Spring guys recognize the problem rather quickly. In later versions, they provide annotation-based dependency injection and Java-based configuration. From Spring 2.5 annotation-based dependency injection was introduced, which automatically scans and register classes as Spring bean which is annotated using @Component annotation. This means you don't to declare that bean using the <bean> tag and inject the dependency, it will be done automatically by Spring. This functionality was enabled and disabled using <context:component-scan> tag.

10 Tools Every Software Developer/Programmer should know

Every trade has their tools and software development is no different. A good programmer or software developer generally know their tools better than others and also have access to more powerful and advanced tools than a average programmer, but there are certain tools which you expect every software developer should know and this list is all about such tools. In this list, I am going to share 10 essential tools, which I believe every programmer or software developer should know and know well.
