In this introduction I will be building code examples for demonstration. I will tell them about the types of Java applications they can learn to build. First I'll make sure they have installed Java Developer Kit. Next check their code editor. How to bring up the console. How to make a source file. How to compile it and run it. If we have enough time I will explain some basics of a source file, object definition, statements, expressions, decisions, loops, fields(data) and methods(subroutines or functions). Next packages(modules).  After that I will talk a bit about tools such as integrated development environments(IDE), code repositories(github) and other resources. My goal is to give them necessary basic tools and insightful information so that their curiosity will lead them further.
