Welcome back to the Java From Scratch series! In this second lesson, we’ll be diving into some basic programming concepts that will allow us to start writing our first Java programs.
In this lesson, we’ll focus on three main topics: Java output, comments, and variables. Java output refers to the ability to display information to the user, whether it’s text or numbers. Comments are used to add notes and explanations to our code, which can be helpful for both ourselves and other developers who may work on the same code in the future. Finally, variables are used to store data that our programs will use.

We’ll start by looking at Java output. We’ll cover the basics of printing text to the console, as well as how to format numbers and other data types for display. Next, we’ll dive into comments, and explore the different types of comments available in Java, as well as when and how to use them effectively.
Finally, we’ll introduce variables, which are essential to any programming language. We’ll cover the different data types available in Java, such as integers, floating-point numbers, and strings, and how to declare and initialize variables.

By the end of this lesson, you’ll have a solid understanding of how to output information to the user, use comments effectively in your code, and declare and initialize variables in Java. These are essential building blocks of any Java program, and will set you up for success as you continue to learn and grow as a Java developer.
