Java
Programming with Mosh
Mosh is a software engineer with two decades of
experience and he's taught over 3 million people how to
code. He's designed this course for anyone who wants to
learn Java if you're a beginner do n't worry I 'll make Java
super simple and hold your hands through this entire
course. I hope you'll stick around and learn this beautiful
and powerful programming language. We 're gon na look
at the anatomy of a Java program in this java tutorial. The
smallest building block in java programs are functions if
function is a block of code that performs a task as a
metaphor think of the buttons on the remote control of
your TV. IntelliJ IDEA is absolutely free and it 's more than
enough for this course so download all right now. After the
parentheses we had 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.
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 so as our applications grow we 're gon na
end up with hundreds or even thousands of classes so we
should properly organize this class us into packages. The
base package for a Java project is the domain name of
your company in Reverse. Code editor might look a little
bit intimidating at first but trust me it 's really easy and
you 're gon na learn about it throughout this course. For
now just type a base package for your project it can
become that your name or whatever it does n't really
matter all right now let 's go forward. Marsh has put
together a comprehensive cheat sheet with summary
notes that you can download below this video. IntelliJ is
building our application and we can see the result in this
little terminal window so here's our hello work message so
that was our first Java program next I 'm going to explain
how Java code gets executed under the hood.
