Learning Java - Variables and Comments
Welcome to a video in the Learning Java Playlist where we learn how to code in Java. While we assuming you are a beginner, we also are assuming you've had some experience in other coding languages like C/C++, Python, or others. If you are looking for practice problems to try: • Java Practice Programming Examples

In this video we look at how to declare and initialize basic primitive data types such as Booleans, integers, doubles, and more. We look at these from both a class level as well as declaring variables inside a method.
Part of this is knowing how to name variables, so we look at what is required for a legal identifier (variable or method name) in Java, as well as standard naming conventions.
Next we move into comments, where we look at the three types of comments Java has. Inline, or single line comments, multiline comments, and a derivative of multi-line comments, the Java Doc comment.
