Java Tutorial for Beginners
Programming on Text
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 or application
programming interfaces
