Writing Your First Java Program

We can do a lot with Java. We can write complex algorithms, build mobile and desktop applications, design cool games, and even make sketches on the console!

But let’s slow down a little. Let’s start with a very basic application to get familiar with the nuts and bolts of a basic Java program.

As you go on to learn more programming languages in the future (hopefully!), you will encounter more “Hello World!” programs.
