## From the instructor

> I am self-taught in Java with many years of experience delivering large-scale solutions ranging from microservices to web and mobile and AI applications for government and commercial clients.I have multiple Java badges on Stack Overflow, and I was even a Sun Certified Java Programmer when that was still a thing and when I thought certifications really meant something.

## Description

According to Oracle, almost 20 billion devices run Java. It was the first language for Android, and it powers AI, microservices, serverless, machine learning pipelines, and much of the critical infrastructure in modern applications.

Java For Work starts from primitives like conditionals, loops, and objects and builds up to the topics that matter at work: AI, security, structured concurrency, functional programming, cloud-native APIs, and observability you won't find covered together anywhere else.

### What makes this course different

The typical Java course teaches you to code in Java, not to build production software in Java. Those are different skills, so you go back to work ready for toy LeetCode problems and unprepared for what your team faces when it has to deliver for real customers.

Java for Work rests on a simple premise: the greatest asset in professional engineering is understanding the craft of building software, not memorizing syntax. The course uses Java 25, the latest LTS release companies should migrate to as soon as possible, and applies hard lessons learned over many years about architecting and designing code for maintainability and productivity.

When you finish this course, you will be a professional Java engineer.
