If the organization you are in follows the Agile methodology, most likely, several IT teams work on individual projects. If you have any suggestions or feedback then you are most welcome, we all learn from each other.P.S.
Unit testing
This enclave serves as a self-contained space for the execution of Java programs, rendering them platform-agnostic and immune to variations in the host machine’s platform or operating system. The linchpin of the Java ecosystem is the Java Virtual Machine, often referred to as JVM. It serves as the cornerstone that enables Java programs to be authored on one machine while retaining the ability to run seamlessly on any other.
Moreover, a solid command of full stack developer skills in Java is essential for creating versatile and robust web applications.
