Lesson 1 - Hello World

Getting started

Hi there! Welcome to your first lesson of the Java course!

In order to complete this lesson you’ll have to write some Java code to display the text “Hello World!” on the console.

Code Snippet

The command for displaying text on the console has the following structure: System.out.println(<insert text>);

Note that with this command - as with every command in Java - you have to end with a semicolon (;).
