How do you actually use Java?

I’m sure this will seem like a silly question. Yet, while I understand the syntax and coding conventions etc it’s never shown how this applies to an actual program?

For example if I wanted to develop a HR management system for my company, how do I actually deploy this onto their system?

I have never made a program with java myself, but I'd imagine you'd compile it.

Zimri Leijen thanks for stopping by, maybe my question is incorrectly phrased. It’s widely stated Java is used by Google, Amazon and other well known brands. Yet I’m unclear how the programs are implemented on their systems. I guess my question is what are the practical applications of Java and why aren’t there any examples?

Java is used for a variety of portable system software, not just for web application development. When it is used for web application development, it is used in combination with a web application server like Apache Tomcat, RedHat JBOSS, Oracle WebLogic, or IBM WebSphere. Such combinations can make very scalable high end servers.
