Ask HN: How would you teach Java to at risk youth?

I recently had the privilege of being picked to teach Java to at risk youth, but I feel like I am in need of some advice as per where to start.

I'm not having an issue with dealing with the kids, it's just what angle should I start with? Should I start with the basics of what happens when you type "System.out.println()"? the JVM? OOP? Should I just go into how to do variables, loops, and if statements and let them build a slow understanding through use of the language?

thanks so much!
