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.
