Java Tutorial for Beginners
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.
IntelliJ uses the Java compiler to compile our code into a different format called Java bytecode.
This Java code is platform independent and that means it can run on Windows Mac Linux or
any operating systems that has a Java runtime environment. Java applications are portable or
platform independent. Java was developed by James Gosling in 1995 at Sun Microsystems
which was later acquired by Oracle in 2010. Java has close to 9 million developers worldwide
currently about 3 billion mobile phones run Java as well as 120 million TV sets and every
blu-ray player. Average salary of a Java developer is just over $ 100,000 per year in the US.
This course is the first part of my complete four-part Java series. Each part is about three to four
hours long so it can easily complete it in a day or two. The first part will give you a solid
foundation on how to start programming in Java in the second part we 'll talk about object
oriented programming which is a style of programming use in most if not all Java applications.
The third part will talk about core Java API is orapplication programming interfaces.
