Java Tutorial for Beginners
software engineer with over two decades of experience
and has taught over 3 million people how to code. He
has designed this course for anyone who wants to learn
Java. If you're a beginner, don't worry - Mosh promises
to make Java super simple and hold your hand through
this course. He hopes you'll stick around and learn this
beautiful and powerful programming language.
The Anatomy of a Java Program
In this Java tutorial, we'll be looking at the basics of a
Java program. The smallest building block in Java
programs are functions. If a function is a block of code
that performs a task, think of the buttons on the remote
control of your TV. Every Java program should have at
least one function and that function is called main .
Writing Java Code
After the parentheses, we have a pair of curly braces
and inside these braces, we write the actual Java code.
Every Java program should have at least one function
and that function is called main . So, main is the entry
point to our programs. Whenever we execute a Java
program, the main function gets called and the code
inside this function gets executed.
Downloading IntelliJ IDEA
IntelliJ IDEA is absolutely free and it's more than enough
for this course, so download it now.
A class is a container for related methods, so we use classes
to organize our code. By the same token, we have a concept
called package, and we use a package to group related
classes.
As our applications grow, we're going to end up with hundreds
or even thousands of classes, so we should properly organize
