The last couple of years was the year of releases for Java developers. With versions of JDK 9 to JDK 15, Spring 5, Spring Boot 2.0, and Spring Security 5.0, there was so much to learn for Java developers and all at once, but like many others, I didn't make a good process, and I am looking to turn it around this year. One of my top priority goals for this year is to learn new Java features as quickly as possible to write more about them. It's also essential for you to learn modern Java features to write better code and improve your day-to-day productivity with Java. The Java 9 release intends to change the way Java developers used to write code. It introduces a modular JDK so that developers can only include the modules that they need.
